VERTICAL COMMUNICATIONS, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED C
ONSOLIDATED FINANCIAL STATEMENTS

(1) BASIS OF PRESENTATION

Vertical Communications, Inc. (formerly Artisoft, Inc) (the Company, we, our, us or the
Registrant), develops, markets and sells business phone systems, software, hardware and associated services. We sell our products through distributors, resellers and system integrators such as AT&T, Fujitsu, IBM and Graybar, and we
engage in alliances with those parties and other technology vendors to assist us in selling and marketing our products. Most of our end user customers rely upon resellers or systems integrators to implement our products, and these resellers and
systems integrators can significantly influence our customers purchasing decisions. We market and sell our products in the United States, Europe and Latin America. We also have distributor relationships in Africa, Asia, Australia and the
Middle East.

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and our wholly
owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.

The accompanying unaudited
condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and pursuant to the rules and regulations of the Securities and Exchange Commission (the
SEC). The balance sheet amounts at June 30, 2006 in this report were derived from our audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2006. In the opinion of
management, the accompanying financial statements include all adjustments of a normal recurring nature which are necessary for a fair presentation of the financial results for the interim periods presented. Certain information and footnote
disclosures normally included in financial statements have been condensed or omitted pursuant to such rules and regulations. Although we believe that the disclosures are adequate to make the information presented not misleading, we recommend that
these financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2006 on file with the SEC. The results of
operations for the three and six months ended December 31, 2006 are not necessarily indicative of the results to be expected for the full year or any other future periods.

The preparation of these financial statements requires us to make estimates and judgments that affect the reported amount of assets and liabilities at
the date of the financial statements and revenues and expenses during the reported period. Areas where significant judgments are made include, but are not limited to, revenue recognition, as well as the accounting for our acquisition of Vodavi
Technology, Inc. as discussed below. Actual results could differ materially from these estimates. The accounting policies applied are consistent with those disclosed in our Annual Report on Form 10-K as disclosed in Note 2.

Acquisition of Vodavi Technology, Inc.

On
December 1, 2006, we completed the acquisition of all of the outstanding securities of Vodavi Technology, Inc. (Vodavi) pursuant to an Agreement and Plan of Merger dated as of October 18, 2006 (the Merger
Agreement), by and among the Company, Vodavi and Vertical Acquisition Sub Inc., a Delaware corporation and wholly-owned subsidiary of the Company (MergerSub). MergerSub was merged with and into Vodavi (the Merger), with
Vodavi continuing its corporate existence as a wholly-owned subsidiary of the Company. Pursuant to the Merger Agreement, each issued and outstanding share of common stock of Vodavi was converted into the right to receive $7.50 in cash, without
interest, on the terms specified in the Merger Agreement. Immediately prior to the effective time of the Merger, all outstanding options to purchase shares of Vodavi capital stock, whether vested or not vested, were exercised pursuant to a cashless
exercise procedure and all equity incentive plans administered by Vodavi were terminated.

Vodavi is a provider of traditional and
next-generation business telecommunications solutions, targeted to small and medium-sized business, primarily in the United States. The aggregate consideration paid by the Company to the stockholders of Vodavi was approximately $31.1 million in cash
(the Merger Consideration). In addition, the Company incurred approximately $0.5 million in transaction costs related to the merger.

The operational results of this acquisition are included in all periods since December 1, 2006, the date that the merger was consummated.

(2) SIGNIFICANT ACCOUNTING POLICIES

Stock-Based Compensation

On July 1, 2005, we adopted the provisions of FASB Statement No. 123 (revised 2004) Accounting for Stock-Based Compensation(SFAS
No. 123R) and elected to use the modified prospective transition method. The modified prospective transition

method requires that compensation cost be recognized in the financial statements for all awards granted after the date of adoption as well as for existing
awards for which the requisite service has not been rendered as of the date of adoption. As a part of this adoption method, prior periods are not restated. Prior to July 1, 2005, the Company applied Accounting Principles Board (APB)
Opinion No. 25, Accounting for Stock Issued to Employeesin accounting for its stock incentive plan and accordingly, compensation cost was recognized for its stock options in the financial statements when the exercise price was below the
fair market value.

On October 20, 1994, the Companys shareholders approved the Companys 1994 Stock Incentive Plan (the
1994 Plan). The 1994 Plan provides for the grant of Incentive Stock Options, Nonqualified Stock Options, Stock Appreciation Rights (Tandem and Free-standing), Restricted Stock, Deferred Stock, Performance Units and Performance Shares to
officers, key employees, non-employee directors and certain consultants of the Company. This Plan was replaced by the 2004 Stock Incentive Plan (the 2004 Plan) that was approved by the Companys shareholders on March 15, 2004.

The 2004 Plan initially provided that the maximum number of options that could be granted would be 2,000,000 shares, plus the lesser of
150,000 shares of common stock or 1.5% of the number of shares of common stock issued and outstanding as of July 1 of each year commencing on July 1, 2004 (the Evergreen clause). On September 28, 2004, the 2004 Plan was
amended to provide that the maximum number of options that can be granted would be increased to 8,236,255 shares and the Evergreen clause was removed from the plan so that the maximum number of shares that could be granted would no longer increase
automatically each year. On April 3, 2006, the 2004 Plan was amended to provide that the maximum number of options that can be granted would be increased to 10,768,865. On October 18, 2006, the 2004 Plan was amended to provide that the
maximum number of options that can be granted would be increased to 24,584,167.

The adoption of SFAS No. 123R increased loss from
operations and net loss for the three and six months ended December 31, 2006 by $1.0 million ($0.02 per basic and diluted share) and $2.0 million ($0.04 per basic and diluted share), respectively. As of December 31, 2006, $8.1 million of
unvested stock-based compensation has not yet been recognized by the Company. The unvested stock-based compensation balance is expected to be expensed over a weighted average period of 2.5 years. The adoption of SFAS No. 123R increased loss
from operations and net income for the three and six months ended December 31, 2005 by $1.0 million ($0.02 per basic and diluted share) and $2.2 million ($0.05 per basic and diluted share), respectively.

The following table summarizes the allocation of stock-based compensation from employee stock options included in operating expenses by line item in the
Unaudited Consolidated Condensed Statements of Operations for the periods indicated (in thousands):

Generally, options become exercisable over a four-year period commencing on the date of the grant.
Options granted prior to and after September 28, 2004 vest 25% at the first anniversary of the grant date with the remaining 75% vesting in equal monthly increments over the remaining three years of the vesting period. Options granted on
September 28, 2004 vest 2.08% monthly. In computing stock based compensation, we apply an estimated forfeiture rate based on actual forfeitures in our recent history. The fair value of options granted was calculated using the Black-Scholes
option-pricing model with the following weighted average assumptions:

The risk-free interest rate is based upon the U. S. Treasury securities yield. The term of the
options grant is derived from historical data. The expected volatility is based upon the historical volatility of the Companys common stock over the period of time.

Goodwill

The Company accounts for its goodwill in accordance with the provisions of FASB Statement No. 142, Goodwill and Other Intangible Assets. This statement requires that goodwill be periodically
tested for impairment, with impaired assets written down to fair value. As of September 1, 2006, the Company conducted its annual impairment test of goodwill by comparing fair value to the carrying amount of its underlying assets and
liabilities. The Company determined that the fair value exceeded the carrying amount of the assets and liabilities, therefore no impairment existed as of the testing date.

(3) ACQUISITIONS

Vertical Networks, Inc.

On September 28, 2004, we acquired substantially all of the assets, other than patents and patent rights and most of the liabilities, of Vertical
Networks Inc. (Vertical Networks). Vertical Networks was a leading provider of distributed IP-PBX software and communications solutions to large enterprises. We also received a patent license for the use of all of Vertical Networks
patents and patent applications other than Vertical Networks rights under specified patents that do not relate to the business we purchased. In addition, we assumed specific liabilities of Vertical Networks.

The purchase price for Vertical Networks consisted of: $12.5 million in cash, paid at closing, with an additional $1.0 million held in escrow to secure
Vertical Networks indemnification obligations to us, $1.0 million in transaction costs, the assumption of most liabilities of Vertical Networks and an earnout provision of up to $4.3 million. The earnout obligation is equal to the first $4.3
million of non-refundable software license revenues collected by us from CVS Pharmacy, Inc. (CVS) in connection with a specific contract. We have paid $1.7 million of the earn-out provision and accrued an additional $0.6 million of the
earn-out provision through December 31, 2006. As of June 30, 2006, the entire $1.0 million in escrow was released to Vertical Networks.

Comdial Corporation

On September 28, 2005, we completed the acquisition of substantially all of the assets (the
Comdial Assets) of Comdial Corporation (Comdial) pursuant to the terms of an asset purchase agreement entered into on September 1, 2005. The Comdial Assets included all of Comdials intellectual property, fixed
assets, equipment, inventories, accounts receivable, rights under contracts and leases, cash and other current assets.

In exchange for the
acquired assets, we (i) delivered $14.5 million in cash, (ii) executed an 8% secured promissory note in the aggregate principal amount of $2.5 million to Comdial (see Note 6), (iii) repaid $1.7 million of debtor-in-possession
financing incurred to fund operations of Comdial prior to the closing, (iv) repaid an amended and restated note dated May 25, 2005, issued by Comdial to Dialcom Acquisition, LLC, in the principal amount of $1.9 million and (v) paid
$0.4 million and assumed $0.2 million of Comdials remaining obligations under a key employee retention plan with Comdials employees, as approved by an order of the Bankruptcy Court. In addition, we incurred approximately $0.8 million in
transaction costs related to the acquisition.

We also assumed certain liabilities of Comdial such as post petition ordinary course trade payables
outstanding as of the acquisition date, certain employee related obligations, and certain customer related obligations and liabilities related to certain assumed executory contracts. In addition, we assumed pre-petition and post petition obligations
under remaining unfulfilled purchase orders outstanding as of the closing date. The amount of the liabilities we assumed as of September 28, 2005 was approximately $8.9 million, which included $6.0 million in open purchase order obligations.

Vodavi Technology, Inc.

On
December 1, 2006, Vertical completed the acquisition of all of the outstanding securities of Vodavi pursuant to the Merger Agreement, by and among the Company, Vodavi and MergerSub wherein MergerSub was merged with and into Vodavi, with Vodavi
continuing its corporate existence as a wholly-owned subsidiary of the Company.

Pursuant to the Merger Agreement, each issued and
outstanding share of common stock of Vodavi was converted into the right to receive $7.50 in cash, without interest, on the terms specified in the Merger Agreement. Immediately prior to the effective time of the Merger, all outstanding options to
purchase shares of Vodavi capital stock, whether vested or not vested, were exercised pursuant to a cashless exercise procedure and all equity incentive plans administered by Vodavi were terminated. The aggregate consideration paid by the Company to
the stockholders of Vodavi was approximately $31.1 million in cash. In addition, the Company incurred approximately $0.5 million in transaction costs related to the merger.

The Company obtained the Merger Consideration (a) through the sale of 27,400 shares of its newly designated Series E convertible preferred
stock, par value $1.00 per share, at a purchase price of $1,000 per share to certain investors pursuant to a Securities Purchase Agreement, as amended and restated (the Amended and Restated Securities Purchase Agreement), and (b) by
entering into a Credit Agreement (the Credit Agreement) dated as of October 18, 2006, by and among the Company, Vertical Communications Acquisition Corp., a Delaware corporation (VCAC), Columbia Partners, L.L.C.
Investment Management (Investment Manager), and NEIPF, L.P. (Lender), pursuant to which the Company issued (i) a senior secured promissory note payable to Lender in the principal amount of $10.0 million; and (ii) a
senior secured promissory note payable to Lender in the principal amount of $15.0 million.

The following table represents the estimated
allocation of the purchase price for our acquisition of Vodavi over the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition.

The estimated values of current assets, excluding inventory, and liabilities were based upon their
historical costs on the date of acquisition due to their short-term nature. Inventory was valued at estimated selling prices less the sum of (i) the cost of disposal and (ii) a reasonable profit allowance for the selling effort. Property
and equipment was also estimated based upon its historical cost as there was no appreciated real estate and the historical costs of the office equipment, furniture and machinery most closely approximated fair value. The identified intangible assets
were valued at their fair value as of the acquisition date. This valuation is preliminary and subject to change when the appraisal is complete. The associated deferred income tax liability is preliminary and also subject to change pending the
Companys analysis of its ownership changes and the impact on the availability of the Companys deferred tax assets. The residual purchase price was recorded as goodwill.

The preliminary amounts assigned to identifiable intangible assets acquired was based on their
respective fair values determined as of the acquisition date using a discounted cash flow analysis and relief from royalty methodology. The valuation is preliminary and is subject to change. The excess of the purchase price over the tangible and
identifiable intangible assets was recorded as goodwill and amounted to approximately $14.0 million. In accordance with current accounting standards, the goodwill is not being amortized and will be tested for impairment annually in the fourth
quarter of our fiscal year, as required by SFAS No. 142 or more often if impairment indicators arise.

The pro forma adjustments include the amortization expense for the acquired identifiable
intangible assets of approximately $0.4 million per quarter and the interest expense for the amounts borrowed to finance the acquisition of approximately $1.7 million per quarter.

Pursuant to EITF 95-3, Recognition of Liabilities in Connection with a Purchase Business Combination,the Company recorded a liability of $0.4
million related to the planned employee involuntary termination costs as a result of the acquisition. The Companys management began the assessment and formulation of a plan as of the acquisition date and is in the process of completing the
assessment of the number of employees, their job classifications and their locations that will be affected. The liability recorded includes the anticipated severance and benefits costs that the Company will pay to the involuntarily terminated
employees. The Company expects to complete the planned actions prior to October 2006.

The acquisition of the assets of Vodavi on December 1, 2006 is the primary reason for the
substantial increase in inventory, adding $4.3 million in inventory as of December 31, 2006. The remainder of the increase is primarily due to an increase in the number of phones on hand.

(6) DEBT

Debt Related to Comdial Acquisition

We financed a portion of the purchase price for the Comdial
Assets (the 2005 Debt Financing) by entering into a loan agreement with Silicon Valley Bank (SVB) on September 28, 2005 (the SVB Loan Agreement). The SVB Loan Agreement terms provided the Company with a
revolving line of credit in an amount not to exceed $7,000,000 (the Revolving Loan), as well as a $2,000,000 term loan (the Term Loan). The Revolving Loan initially matured on September 27, 2006. On September 27,
2006, the Company entered into a Third Loan Modification Agreement with SVB under which the maturity date of the Revolving Loan was extended from September 27, 2006 to October 31, 2006. In addition, the credit limit was redefined as the
lesser of (A) $7,000,000 less the amounts outstanding under the term loan and the amounts outstanding for letter of credit or cash management services, or (B) 80% of eligible accounts receivable plus 20% of eligible inventory less the
amounts outstanding under the term loan and the amounts outstanding for letter of credit or cash management services. The interest rate on the Revolving Loan was changed to the Prime Rate plus 1.75% per annum and the interest rate
on the Term Loan was changed to the Prime Rate plus 2.25% per annum. Certain of the provisions of the financial covenants were modified to eliminate the minimum cash balances covenant and add a minimum equity raise covenant which
specified that the Company must receive a minimum of $5,000,000 in net proceeds from the issuance of equity securities and/or subordinated debt on or before November 1, 2006. In addition the minimum earnings before interest, taxes, depreciation
and amortization covenant was modified.

The Term Loan was payable in monthly principal installments of $133,333 plus interest, due
beginning July 31, 2006 through and until the maturity date of September 26, 2007.

##### Table of Contents

On September 28, 2005 (the Closing Date) the Company also executed a secured promissory
note in the aggregate principal amount of $2,500,000 (the Comdial Note). The Comdial Note was issued to the Comdial bankruptcy estate (the Comdial Estate) in connection with the acquisition of the Comdial Assets. The Comdial
Note was subject to interest at the rate of 8% per annum and initially matured on the first anniversary of the Closing Date. On September 28, 2006, the Company and the Comdial Estate entered into a agreement which extended the maturity
date of the Comdial Note from September 28, 2006 to November 1, 2006. The note was made subject to the minimum equity raise and minimum earnings before interest, taxes, depreciation and amortization covenants contained in the SVB Revolving
Loan modification dated September 27, 2006. In addition, the Company was required to pay an extension fee of $150,000 plus all accrued interest on the note through September 28, 2006 up to a maximum of $400,000. Because the Company paid
off the Comdial Note in full prior to November 1, 2006, the extension fee was reduced to $75,000.

On October 18, 2006, the
Company issued a Senior Secured Promissory Note with NEIPF, L.P. (see below for additional detail). The Company used proceeds from this loan to extinguish all of the outstanding loans with SVB and the Comdial Estate.

Debt Related to Vodavi Acquisition

On
October 18, 2006, the Company entered into the Credit Agreement, a Security Agreement, a Pledge Agreement and an Intellectual Property Security Agreement by and among the Company, VCAC, Investment Manager and Lender. Pursuant to the Credit
Agreement, the Company agreed to (a) issue a senior secured promissory note payable to Lender (the Initial Bridge Note) in the amount of $10.0 million, (b) providing certain conditions were met, issue a senior secured
promissory note payable to Lender (the Subsequent Bridge Note) in the principal amount of $5.0 million; (c) issue a senior secured promissory note payable to Lender (the Term Note and, together with the Initial Bridge
Note, the Loans) in the principal amount of $15.0 million; and (d) upon the issuance of the Initial Bridge Note, issue to Lender (i) a warrant to purchase 4,500,000 shares of the Companys common stock at an exercise price
equal to $0.01 per share (the Lender Warrant) and (ii) an additional warrant for the purchase of 500,000 shares of the Companys common stock at an exercise price equal to $0.01 per share. The Subsequent Bridge Note was not
issued and the additional warrant for the purchase of 500,000 shares of the Companys common stock became null and void when the Company reached a specified commitment level in the sale of its Series E convertible preferred stock (see Note 9).

The Loans are secured by substantially all of the assets of the Company including specifically all rights in the outstanding shares of
capital stock of VCAC held by the Company and certain intellectual property owned by the Company. Events of default under the Credit Agreement include failure by the Company to meet its obligations under the Credit Agreement and any other
outstanding indebtedness; breach of certain of its obligations and covenants under the Credit Agreement; breach of any representations and warranties made in any documents relating to the Loans; the Companys insolvency and/or bankruptcy; the
Companys incurrence of a final money judgment against its assets in excess of $250,000 per individual case or $1.0 million in the aggregate; the Companys receipt of an order requiring dissolution or split up; and the Companys or
any creditor of the Companys failure to comply with any subordination provisions in any document which benefit the Lender or Investment Manager. Should an Event of Default occur, remedies available to the Lender include acceleration requiring
immediate payment of all or any portion of the obligations under the Credit Agreement and, with prior written consent of the Investment Manager, the right to set off any of the Companys property held by the Lender against the obligations.

The Credit Agreement contains certain financial covenants under which the Company must (a) maintain cash, cash equivalents or
available borrowing capacity of at least $5.0 million for each fiscal quarter beginning with the quarter ending December 31, 2006; (b) beginning with the trailing twelve month period ended September 30, 2007 and for each quarter
thereafter, maintain a minimum EBITDA of $1.00; (c) beginning with the trailing twelve month period ended September 30, 2007, maintain minimum total consolidated revenues of $80.0 million and (d) for the six month period ended
March 31, 2007, maintain minimum total consolidated revenues of $30.0 million and minimum EBITDA of ($2.0) million.

The Initial
Bridge Note was issued on October 18, 2006 in the amount of $10.0 million and bears interest at the rate of 14% per annum. Interest is paid quarterly in arrears. The principal amount and any unpaid interest are payable in full on
July 1, 2007. The net proceeds from the Initial Bridge Note, after payment of costs of approximately $0.2 million, were utilized to retire all of the debt owed to SVB and the Comdial Estate with the remainder to supplement working capital. The
Lender Warrant is exercisable by the holder at any time until its expiration on October 18, 2013 either by paying the exercise price of $.01 per share or on a cashless exchange basis. This net exercise right is generally limited to times when
the Company is not in compliance with its obligations relating to the registration of the shares of common stock underlying the warrants for resale under the Companys registration rights agreement with respect to those shares. The number of
shares issuable upon exercise and the per share exercise price of the warrant is subject to adjustment in the case of any stock dividend, stock split, combination, capital reorganization, reclassification or merger or consolidation. Subject to
limited exceptions, the number of shares of common stock for which the warrant is exercisable is also subject to adjustment in the case of an issuance of shares of common stock or securities exercisable for or convertible into common stock, at a per
share price less than the exercise price of the warrant then in effect. In the event of such an issuance, the exercise price of the warrant will be reduced to equal the per share price of the newly issued securities. The conversion price, as defined
in the warrants, shall also be reduced to equal the purchase price of the new issuance of common stock (or securities convertible into common stock).

##### Table of Contents

We allocated the proceeds between the debt and the warrant based upon their relative fair values as of
the issuance date, resulting in $2.1 million being allocated to the warrants. We determined the fair value of the warrants using the Black-Scholes option pricing model with the following assumptions: no dividend yield; weighted average risk free
rate of 4.42%; volatility of 115% and a contractual life of 7 years. The proceeds attributable to the warrant were recorded as a discount on the debt which will be accreted, with the deferred issuance costs and cash interest, over the term of the
Initial Bridge Note using the effective interest method.

The Term Note was issued on December 1, 2006 in the amount of $15.0 million
and bears interest at a rate per annum equal to the applicable federal rate for the term of the Term Note. A portion of the interest accruing equal to .05% of the outstanding principal amount is payable quarterly in arrears. The Company is also
obligated to pay the Lender a premium equal to the amount required to provide the Lender with a rate of return of 13.5% per annum upon any payment or prepayment of any amount of the Term Note. This premium is subject to increase to 15.5% for
any period in which an Event of Default occurs and continues. The principal amount of the Term Note and any unpaid interest, including the payment premium, is payable in full on October 17, 2009. Cash interest, the premium and deferred issuance
costs of $0.3 million will be accreted over the life of term note using the effective interest method.

As of December 31, 2006, the
Company is in compliance with the applicable financial covenants of the Loans.

(7) INCOME TAXES

The Company has not recognized any current income tax expense in any period presented due to the Companys net losses. However, in fiscal years
beginning with 2005, the Company is recording a deferred tax provision and corresponding liability arising from the timing differences associated with amortizing goodwill for income tax purposes over a 15 year life.

(8) CONVERTIBLE REDEEMABLE PREFERRED STOCK

Series D Preferred
Stock

On February 9, 2006, the Company completed the sale (the Series D Financing) of 5,000 shares of its
newly designated Series D Convertible Preferred Stock, par value $1.00 per share (the Series D Preferred Stock) and warrants to purchase an aggregate of 1,041,667 shares (the Warrants) of the Companys common
stock pursuant to a Securities Purchase Agreement (the 2006 Securities Purchase Agreement) between the Company and certain investors (the Series D Investors). The aggregate proceeds to the Company from the Series D
Financing was $5.0 million.

Obligation to Register Shares

Pursuant to the 2006 Securities Purchase Agreement, we agreed to register the shares of common stock issuable upon conversion of the Series D Preferred Stock and upon exercise of the Warrants (collectively, the
Issued Shares) for resale by the Series D Investors under the Securities Act. The Company also agreed to file with the SEC a registration statement with respect to the Issued Shares no later than March 27, 2006 (the
Filing Date), and to use our best efforts to cause the registration statement to become effective on or before the date that is the earlier of (1) in the event of no review by the SEC, within five days of being informed by the SEC
that the SEC has decided not to review the registration statement, but in no event later than 30 days after the Filing Date, (2) in the event of a review by the SEC, within five days of being informed by the SEC that the SEC has no further
comments on such registration statement, but in no event later than 90 days after the Filing Date (the earlier of (1) and (2), the Required Effective Date).

The Company is currently liable for liquidated damages to each Series D Investor because the registration statement was not filed on or before
March 27, 2006 (such an event, a Filing Default). As a result of the Filing Default, the Company must pay as liquidated damages to the Series D Investors, for each 30-day period of a default, an amount in cash equal to 1% of
the aggregate purchase price paid by the Series D Investor pursuant to the 2006 Securities Purchase Agreement; provided that in no event will the aggregate amount of cash to be paid as liquidated damages exceed 9% of the aggregate purchase
price paid by such Series D Investor. As of December 31, 2006, the Company has accrued $450,000 in liquidated damages as a result of the Filing Default.

Material Terms

The material terms of the Companys Series D Preferred Stock are summarized below.

Dividends. From the date of issuance, the Series D Preferred Stock accrues dividends at a rate of $80.00 per year and compounds annually.
Dividends on the Series D Preferred Stock may be declared and paid from time to time as determined by the Companys board of directors. The Company cannot declare, pay or set aside any dividends or distributions on any other shares of
capital stock of the Company unless the holders of Series D Preferred Stock first receive or simultaneously receive a dividend or distribution on each outstanding share of Series D Preferred Stock in such amounts as set forth in the
Certificate of Powers, Designation, Preferences and Rights of the Series D Preferred Stock (the Certificate of Designations).

Anti-dilution Adjustments. In the event the Company issues additional shares of common stock
(which includes certain options and convertible securities issued by the Company), except in limited circumstances, for no consideration or for consideration per share that is less than the conversion price of the Series D Preferred Stock then
in effect, the conversion price of the Series D Preferred Stock will be reduced in accordance with the formula set forth in the Certificate of Designations.

Redemption. Beginning February 9, 2009, the Series D Preferred Stock may be redeemed at a price equal to the Original Issue Price, plus all declared and unpaid dividends, provided that the holders of
a majority of the issued and outstanding shares of Series D Preferred Stock consent to such redemption. Commencing 30 days after the consent, the Series D Preferred Stock must be redeemed in three equal annual installments. If the Company fails
to redeem the Series D Preferred Stock in accordance with the Certificate of Designations, then interest will accrue on any unpaid amount at a rate of 1% per each 30-day period that such amounts remain unpaid.

Warrants

In addition to the shares of Series D
Preferred Stock, the Company issued warrants to purchase an aggregate of up to 1,041,667 shares of common stock at a per share exercise price of $0.01. The warrants have a term of exercise expiring on February 9, 2016. The number of shares
issuable upon exercise and the per share exercise price of the warrants is subject to adjustment in the case of any stock dividend, stock split, combination, capital reorganization, reclassification or merger or consolidation. Subject to limited
exceptions, the number of shares of common stock for which the warrant is exercisable is also subject to adjustment in the case of an issuance of shares of common stock or securities exercisable for or convertible into common stock, at a per share
price less than the per share conversion price of the Series D Preferred Stock then in effect. In the event of such an issuance, the number of shares of common stock for which the warrant is exercisable is increased in accordance with the
formula set forth in the warrant. The conversion price, as defined in the warrant, is also reduced to equal the purchase price of the new issuance of common stock (or securities convertible into common stock). The warrants are exercisable at any
time prior to their expiration date by delivering the warrant certificates to the Company, together with a completed election to purchase and the full payment of the exercise price or by means of a net exercise clause under which the
Company does not receive any cash, but rather, the number of shares issued upon exercise is net of the number of shares withheld by the Company in lieu of payment of the exercise price. This net exercise right is generally limited to times when the
Company is not in compliance with its obligations relating to the registration of the shares of common stock underlying the warrants for resale under the Companys registration rights agreement with respect to those shares.

The Company allocated the proceeds between the stock and the warrants based upon their relative fair values as of the closing date, resulting in $951
thousand being allocated to the warrants. We determined the fair value of the warrants using the Black-Scholes option pricing model with the following assumptions: no dividend yield; weighted average risk free rate of 4.54%; volatility of 115% and a
contractual life of 10 years. The Company recorded the portion of the proceeds attributable to the stock as mezzanine equity pursuant to EITF Topic D-98, Classification and Measurement of Redeemable Securitiesafter determining the guidance
in FAS 150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equitydid not apply. The Company determined that the warrants meet the definition of a derivative instrument as defined in SFAS 133,
Accounting for Derivative Instruments and Hedging Activities, but do not require derivative treatment pursuant to the scope exception in paragraph 11(a) of SFAS 133. We recorded the proceeds attributable to the warrants in permanent equity
pursuant to guidance in EITF 00-19,Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Companys Own Stock, as the Company can settle the warrants in unregistered shares and the liquidated damages
are not believed to be uneconomic.

The Company evaluated whether the embedded conversion feature in the stock required
bifurcation and determined that the economic characteristics and risks of the embedded conversion feature in the stock were clearly and closely related to the stock and concluded that bifurcation was not required under SFAS 133. We calculated the
intrinsic value of the beneficial conversion feature embedded in the stock pursuant to the guidance in EITF 00-27, Application of Issue No. 98-5 to Certain Convertible Instruments. The beneficial conversion of $659,000 was recognized as
an additional discount on the stock. The total discount on the stock resulting from the allocation of proceeds to the warrants and recording of the beneficial conversion feature will be accreted over the period through the earliest possible
redemption date.

As a result of the issuance of the Lender Warrant (see Note 6) and the Series E Preferred Stock (see below), the
anti-dilution adjustments in the Series D Preferred Stock and the Warrants were triggered. Accordingly, on December 1, 2006, the Company issued 539,787 additional warrants to the Series D Investors which increased the portion of the proceeds
allocable to the warrants to $1.3 million. In addition, the conversion price was adjusted to $0.79 which resulted in an increase in the value of the beneficial conversion feature to $2.8 million which was recorded as an additional discount on the
stock. The additional discounts recognized as a result of these adjustments will be accreted over the period through the earliest redemption date.

We will reevaluate the classification of the stock and warrants in each period to determine if
reclassification is necessary. Our obligation to the Series D Preferred Stockholders, should they choose to redeem the stock at or after the redemption date is $5.0 million plus accrued but unpaid dividends.

Series E Preferred Stock

On December 1,
2006, the Company completed the sale (the Series E Financing) of 27,400 shares of its newly designated Series E Convertible Preferred Stock, par value $1.00 per share (the Series E Preferred Stock) and warrants
to purchase an aggregate of 25,849,059 shares (the Warrants) of the Companys common stock pursuant to the Amended and Restated Securities Purchase Agreement between the Company and certain investors (the Series E
Investors) (the Series E Securities Purchase Agreement). The aggregate proceeds to the Company from the Series E Financing was $27.4 million.

Obligation to Register Shares

Pursuant to the Amended and Restated Securities Purchase Agreement, we
agreed to register the shares of common stock issuable upon conversion of the Series E Preferred Stock and upon exercise of the Warrants (collectively, the Issued Shares) for resale by the Series E Investors under the Securities
Act. The Company also agreed to file with the SEC a registration statement with respect to the Issued Shares no later than 210 days after the effective time of the Merger, and to use our best efforts to cause the registration statement to become
effective as promptly as reasonably practicable after (1) being informed by the SEC that the SEC has decided not to review the registration statement or (2) being informed by the SEC that the SEC has no further comments on such
Registration Statement.

Other Company Obligations

The Companys negative covenants relate to obligations not to, without the prior consent of M/C Venture Partners, provided M/C Venture Partners holds 50% of the shares of Series E Preferred Stock purchased
in the Series E Financing, (1) enter into a transaction involving a change in control of the Company; (2) incur indebtedness in excess of $3.0 million, subject to specified exceptions; (3) create any security with an equity
component unless that security is junior to the common stock; (4) issue any equity securities; (5) transfer its intellectual property; (6) repurchase, redeem or pay dividends on any shares of capital stock (subject to limited
exceptions); (7) grant stock options that are not authorized by a vote of the Board of Directors or its Compensation Committee; (8) liquidate or dissolve; (9) change the size of the Companys Board of Directors; (10) amend
the Companys certificate of incorporation or bylaws; (11) change the nature of the Companys business; (12) alter the voting rights of shares of the Companys capital stock in a disparate manner; (13) take any action
which would cause an adjustment to the exercise price or number of shares to be delivered under the Section 8 of the Warrants; or (14) amend the Credit Agreement or the warrants issued in connection with the Credit Agreement, or take any
action that would cause any increase in the number of shares for which such warrants would be exchanged.

Material Terms

The material terms of the Companys Series E Preferred Stock are summarized below.

Voting. The holders of Series E Preferred Stock are entitled to vote on any matter presented at any meeting of the stockholders of the Company.
Each holder of Series E Preferred Stock is entitled to cast a number votes equal to the number of whole shares of common stock into which the shares of Series E Preferred Stock are convertible as of the record date for determining stockholders
entitled to vote on such matter. Currently, the issued and outstanding shares of Series E Preferred Stock would convert into an aggregate of 51,698,113 shares of common stock, which represents approximately 31.8% of the total voting power of the
Company on a fully diluted basis.

Dividends. From the date of issuance, the Series E Preferred Stock accrues dividends at a rate of
$100.00 per year and compounds annually. Dividends on the Series E Preferred Stock may be declared and paid from time to time as determined by the Companys board of directors. The Company cannot declare, pay or set aside any dividends or
distributions on any other shares of capital stock of the Company unless the holders of Series E Preferred Stock first receive or simultaneously receive a dividend or distribution on each outstanding share of Series E Preferred Stock in such amounts
as set forth in the Certificate of Powers, Designation, Preferences and Rights of the Series E Preferred Stock (the Certificate of Designations).

Liquidation. Upon liquidation, dissolution or winding up, then the holders of Series E Preferred Stock are entitled, before any distributions are made to the holders of the common stock, or any other class or
series of capital stock of the Company ranking junior to the Series E Preferred Stock as to such distributions, to be paid an amount equal to $1,000 per share (the Original Issue Price) and any unpaid dividends thereon, subject to
adjustment. For purposes of this liquidation preference, unless waived in writing by any single holder of at least thirty percent (30%) of the outstanding Series E Preferred Stock and/or Series D Preferred Stock (as adjusted) then outstanding,
a consolidation or merger of the Company into or with another entity or the sale of all or substantially all of the Companys assets, in each case under circumstances in which the holders of a majority in voting power of the outstanding capital
stock of the Company, immediately prior to such transaction, owned less than a majority in voting power of the outstanding capital stock of the Company or its successor, would be treated as a liquidation, dissolution or winding up of the Company.

##### Table of Contents

Conversion. The holders of the Series E Preferred Stock have the right, at any time and at their
option, to convert each share of Series E Preferred Stock into a number of shares of the Companys common stock determined by dividing the Original Issue Price (as adjusted) by the then-applicable per share conversion price of the Series E
Preferred Stock. The conversion price is subject to adjustment in the case of any stock dividend, stock split, combination, capital reorganization, reclassification, merger or consolidation by the Company. With limited exceptions, the conversion
price is also subject to adjustment in the case of an issuance of shares of the Companys common stock, or securities exercisable for or convertible into the Companys common stock, at a per share price less than the conversion price then
in effect. In the event that this occurs, the conversion price would be reduced to equal the per share price of the newly issued securities. Initially, the conversion price of the Series E Preferred Stock is $0.53 per share. Currently, the Series E
Preferred Stock would convert into 51,698,113 shares of common stock.

Anti-dilution Adjustments. In the event the Company issues
additional shares of common stock (which includes certain options and convertible securities issued by the Company), except in limited circumstances, for no consideration or for consideration per share that is less than the conversion price of the
Series E Preferred Stock then in effect, the conversion price of the Series E Preferred Stock will be reduced to equal the per share price of the newly issued securities.

Redemption. Starting three years from the date the Certificate of Designations is filed, the Series E Preferred Stock may be redeemed in three equal annual installments commencing 30 days after any single
holder of at least thirty percent (30%) of the issued and outstanding shares of Series E Preferred Stock consents to such redemption. The Series E Preferred Stock may be redeemed at a price equal to the Original Issue Price, plus all declared
but unpaid dividends. If the Company fails to redeem the Series E Preferred Stock in accordance with the Certificate of Designations, then interest will accrue on any unpaid amount at a rate of 1% per each 30-day period that such amounts remain
unpaid.

Special Redemption. Upon notice of certain events triggering a mandatory conversion under the Certificate of Designations,
a holder of Series E Preferred Stock may instead elect to have the Company redeem its shares of Series E Preferred Stock (the Special Redemption). Any such shares will be redeemed at a price equal to the Original Issue Price, plus all
declared and unpaid dividends (the Special Redemption Price). If the Company fails to redeem the shares of Series E Preferred Stock pursuant to the Special Redemption, the holders of such shares will sell such shares to any persons that
the Company designates and will sell such shares at the Special Redemption Price.

Warrants

In addition to the shares of Series E Preferred Stock, the Company issued warrants to purchase an aggregate of up to 25,849,059 shares of common stock at
a per share exercise price of $0.58. The warrants have a term of exercise expiring on December 1, 2016. The number of shares issuable upon exercise and the per share exercise price of the warrants is subject to adjustment in the case of any
stock dividend, stock split, combination, capital reorganization, reclassification or merger or consolidation. Subject to limited exceptions, the number of shares of common stock for which the warrant is exercisable is also subject to adjustment in
the case of an issuance of shares of common stock or securities exercisable for or convertible into common stock, at a per share price less than the per share conversion price of the Series E Preferred Stock then in effect. In the event of such an
issuance, the number of shares of common stock for which the warrant is exercisable is increased in accordance with the formula set forth in the warrant. The conversion price, as defined in the warrant, is also reduced to equal the purchase price of
the new issuance of common stock (or securities convertible into common stock). The warrants are exercisable at any time prior to their expiration date by delivering the warrant certificates to the Company, together with a completed election to
purchase and the full payment of the exercise price or by means of a net exercise clause under which the Company does not receive any cash, but rather, the number of shares issued upon exercise is net of the number of shares withheld by
the Company in lieu of payment of the exercise price. This net exercise right is generally limited to times when the Company is not in compliance with its obligations relating to the registration of the shares of common stock underlying the warrants
for resale under the Companys registration rights agreement with respect to those shares.

The Company allocated the proceeds
between the stock and the warrants based upon their relative fair values as of the closing date, resulting in $11.8 million being allocated to the warrants. We determined the fair value of the warrants using the Black-Scholes option pricing model
with the following assumptions: no dividend yield; weighted average risk free rate of 4.43%; volatility of 111% and a contractual life of 10 years. The Company determined that the warrants meet the definition of a derivative instrument as defined in
SFAS 133, Accounting for Derivative Instruments and Hedging Activities, but do not require derivative treatment pursuant to the scope exception in paragraph 11(a) of SFAS 133. We recorded the proceeds attributable to the warrants in permanent
equity pursuant to guidance in EITF 00-19,Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Companys Own Stock.

The Company evaluated whether the embedded conversion feature in the stock required bifurcation and determined that the economic characteristics and risks of the embedded conversion feature in the stock were clearly
and closely related to the stock and concluded that bifurcation was not required under SFAS 133. We calculated the intrinsic value of the beneficial conversion feature embedded in the stock pursuant to the guidance in EITF 00-27, Application of
Issue No. 98-5 to Certain Convertible Instruments.

##### Table of Contents

The beneficial conversion value, as calculated, exceeds the amount of the proceeds allocated to the stock, thus is capped at $15.6 million allocated to the
Series E Preferred Stock, which is recognized as an additional discount on the stock. The Company determined that the portion of the proceeds attributable to the stock should be recorded as mezzanine equity pursuant to EITF Topic D-98,
Classification and Measurement of Redeemable Securitiesafter determining the guidance in FAS 150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equitydid not apply. However, since the total
discount on the stock resulting from the allocation of proceeds to the warrants and recording of the beneficial conversion feature equals the face value of the Series E Preferred Stock, no initial value has been recognized in mezzanine equity for
the Series E preferred stock. The total discount on the stock resulting from the allocation of proceeds to the warrants and recording of the beneficial conversion feature and the cash dividends will be accreted over the period through the earliest
possible redemption date using the effective interest method. Accretion of the discount and dividends for the fiscal years ended June 30, 2007, 2008, 2009 and 2010 will be approximately $0, $7,000, $2.1 million and $33.5 million, respectively.

We will reevaluate the classification of the stock and warrants in each period to determine if reclassification is necessary. Our
obligation to the Series E Preferred Stockholders, should they choose to redeem the stock at or after the redemption date is $27.4 million plus accrued but unpaid dividends.

A material relationship exists between certain of the Series E investors and the Company. Specifically, each of M/C Venture Partners V, L.P. and its
affiliates, Special Situations Fund III, L.P. and its affiliates , Pathfinder Ventures IV, L.L.C. and its affiliates and William Y. Tauscher, the Companys Chief Executive Officer, President and Chairman of the Board, own shares of the
Companys common stock. LG-Nortel Co., Ltd. is the primary supplier of the products sold in the Vodavi business. Additionally, Peter Bailey, through West Laurelhurst LLC, and Scott Pickett are Series E Investors and executive officers of the
Company. Mr. Bailey is a Senior Vice President of the Company and Mr. Pickett is the Companys Chief Technology Officer.

(9) EQUITY

On September 28, 2004 and October 1, 2004, we sold a total of 24,159,468 shares of our common stock at a per share purchase
price of $1.1386 to several investors (the 2004 Investors), including M/C Venture Partners, under the terms of the 2004 Stock Purchase Agreement. In connection with, or prior to the financing, the holders of all shares of our Series B
and Series C Preferred Stock converted those shares into Common Stock.

On September 28, 2005 we sold a total of 11,329,785 shares of
common stock at a per share purchase price of $1.1386, under the terms of the 2005 Stock Purchase Agreement.

As a result of these and
previous financings, we entered into arrangements with certain parties to register shares of our common stock pursuant to the following agreements:



| |  |  | Registration Rights Agreement, dated August 8, 2001 (the 2001 Agreement) related to the Series B Preferred Stock financing;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | Registration Rights Agreement, dated September 27, 2002 (the 2002 Agreement);
| | - |  | -------------------------------------------------------------------------------



| |  |  | Registration Rights Agreement, dated June 27, 2003, (the 2003 Agreement, together with the 2001 Agreement and the 2002 Agreement, the Prior
Agreements) related to the Series C Preferred Stock financing;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the 2004 Stock Purchase Agreement; and
| | - |  | --------------------------------------



| |  |  | the 2005 Stock Purchase Agreement.
| | - |  | ----------------------------------

The 2004 Investors and certain parties to the Prior Agreements (the Prior Investors) holding enough voting power to amend the 2004 Stock Purchase Agreement and the Prior Agreements, executed a consent, waiver, and release
agreement, dated September 28, 2005, pursuant to which the 2004 Investors and the Prior Investors consented to the execution of the 2005 Stock Purchase Agreement (the 2005 Stock Purchase Agreement) and executed agreements to amend
the 2004 Stock Purchase Agreement and the Prior Agreements (collectively, the Amendments). The Amendments effected, among other things, the following:

With respect to the 2004 Stock Purchase Agreement (i) tolled the liquidated damages accrued or accruing under the 2004 Stock Purchase Agreement through September 28, 2005 by reason of our failure to file and
have declared effective by the SEC a registration statement covering the resale of the shares of our common stock purchased pursuant to the 2004 Stock Purchase Agreement (the Liquidated Damages) and (ii) changed the time frame in
which we are obligated to register the shares issued in the 2004 Agreements to match the time frame for registering shares under the 2005 Stock Purchase Agreement and (iii) agreed to issue new warrants to the 2004 investors in lieu of payment
of the Liquidated Damages.

##### Table of Contents

With respect to the Prior Agreements, amended the registration rights provisions of the Prior Agreements
including, among other things, (i) releasing us from any liability and waiving in full, the application of the Prior Agreements with respect to the payment of liquidated damages and permanently, irrevocably and unconditionally waived in full,
any right to the payment of the liquidated damages, whether accrued or accruing, under the Prior Agreements, and (ii) changing the time frame in which we are obligated to register the shares issued in the Prior Agreements to match the time
frame for registering shares under the 2005 Stock Purchase Agreement.

The Company is currently liable for liquidated damages to the 2005
Investors and the 2004 Investors because the registration statement was not declared effective on or before March 12, 2006 (such an event, an Effectiveness Default). As a result of the Effectiveness Default, the Company must pay as
liquidated damages to the 2005 Investors and the 2004 Investors, for each 30-day period of a default, an amount in cash equal to 1% of the aggregate purchase price paid by the Investors; provided that in no event will the aggregate amount of cash to
be paid as liquidated damages exceed 9% of the aggregate purchase price paid by each Investor. As of December 31, 2006, the Company has accrued $2.2 million in liquidated damages as a result of the Effectiveness Default.

(10) COMPUTATION OF NET LOSS PER SHARE

Net loss per
basic and diluted share are based upon the weighted average number of common shares outstanding. Common equivalent shares, consisting of outstanding stock options, convertible preferred shares and warrants to purchase common stock are included in
the diluted per share calculations where the effect of their inclusion would be dilutive. Common stock equivalents have been excluded for all periods presented as they are antidilutive. For the periods ended December 31, 2006 and 2005, total common
stock equivalents excluded are 98.7 million and 10.2 million, respectively.

(11) GUARANTEES

We are subject to lawsuits and other claims arising in the ordinary course of our operations. In the opinion of management, based on consultation with
legal counsel, the effect of such matters will not have a material adverse effect on our financial position or results of operations.

We
enter into standard indemnification agreements in our ordinary course of business. Pursuant to these agreements, we indemnify, hold harmless, and agree to reimburse the indemnified party for losses suffered or incurred by the indemnified party,
generally our business partners or customers, in connection with any patent or any copyright or other intellectual property infringement claim by any third party with respect to our products.

The term of these indemnification agreements is generally perpetual. The maximum potential amount of future payments we could be required to make under
these indemnification agreements is unlimited. We have never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. Accordingly, we have no liabilities recorded for these agreements.

We warrant that our software products will perform in all material respects in accordance with our standard published specifications in effect at the
time of delivery of the licensed products to the customer for 90 days. We warrant that our maintenance services will be performed consistent with generally accepted industry standards through completion of the agreed upon services. Additionally, we
warrant that our hardware products will perform in all material respects in accordance with our standard published specifications in effect at the time of delivery of the products to the customer for the specified periods as per our warranty
policies and agreement. We provide for the estimated cost of hardware product warranties based on specific warranty claims and claim history. If necessary, we would provide for the estimated cost of the software and services warranties based on
specific warranty claims and claim history, however, we have never incurred any significant expenses under our product or service warranties.

Item 2.  MANAGEME
NTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion
together with the consolidated financial statements and related notes appearing elsewhere in this quarterly report on Form 10-Q. This item contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933
and Section 21E of the Securities Exchange Act of 1934 that involve risks and uncertainties. Actual results may differ materially from those included in such forward-looking statements. Factors which could cause actual results to differ
materially include those set forth under Risk Factors as well as those otherwise discussed in this section and elsewhere in this quarterly report on Form 10-Q. See Forward-Looking Statements.

Our discussion and analysis of our financial condition and results of operations are based upon our unaudited condensed consolidated financial
statements, which have been prepared in accordance with accounting principles generally accepted in the United States and the rules and regulations of the SEC. The preparation of these financial statements requires us to make estimates and judgments
that affect the reported amount of assets and liabilities at the date of the financial statements and revenues and expenses during the reporting period. Areas where significant judgments are made include, but are not limited to revenue recognition
and values attributed to the assets and liabilities acquired pertaining to the acquisition of Vodavi. The estimated values of current assets and liabilities and property and equipment were based upon their historical costs in the hands of the seller
on the date of acquisition due to their short-term nature. This amount may be adjusted subsequently when we complete our assessment of the property and equipment that will be utilized in the combined operations and those that will be disposed.

Actual results could differ materially from any one or all of these estimates discussed above. For a more detailed explanation of the
judgments made in these areas, please refer to our annual report on Form 10-K for the year ended June 30, 2006, as filed with the SEC on October 16, 2006.

Critical Accounting Policies

Revenue Recognition

The Company recognizes revenue for the sale of its InstantOffice and TeleVantage products pursuant to Statement of Position (SOP) 97-2, Software
Revenue Recognition, and SOP 98-9, Software Revenue Recognition With Respect to Certain Transactions. For revenue generated by the sale of Comdial products, where the Company has determined that the software is incidental, the Company
follows Staff Accounting Bulletin (SAB) 104, Revenue Recognition. Generally, the Company recognizes revenue when it is realized or realizable and earned. The Company considers revenue realized or realizable and earned when persuasive evidence
of an arrangement exists, the product has been shipped or the services have been provided to the customer, the sales price is fixed or determinable and collectability is reasonably assured. The Company reduces revenue for estimated customer returns,
rotations and sales rebates when such amounts are estimable. When not estimable, the Company defers revenue until the product is sold to the end customer or the customers rights expire. As part of its product sales price, the Company provides
telephone support, which is generally utilized by the customer shortly after the sale. The cost of the phone support is not significant but is accrued in the financial statement. In addition to the aforementioned general policy, the following are
the specific revenue recognition policies for each major category of revenue.

The Company defers revenue on shipments to Toshiba until the
product is resold by Toshiba to its customers. The deferral of revenue is due to the Companys inability to reasonably estimate potential future stock rotations resulting from future product releases and their effect on future revenue as
Toshiba purchases the TeleVantage software and license keys in bulk amounts and maintains an inventory for future sales to customers. For all other TeleVantage license sales, assuming that all other revenue recognition criteria have been met,
revenue is recognized at the time of delivery of the software to the customer.

Revenue from delivered elements of one-time charge licensed
software is recognized at the inception of the license term using the residual method, provided we have vendor-specific objective evidence (VSOE) of the fair value of each undelivered element. Revenue is deferred for the fair value of
the undelivered elements based upon the price of these elements when sold separately. Revenue is also deferred for the entire arrangement if VSOE does not exist for each undelivered contract element. Examples of undelivered elements in which the
timing of delivery is uncertain include contractual elements that give customers rights to any future upgrades at no additional charge or future maintenance that is provided within the overall price. The revenue that is deferred for any contract
element is recognized when all of the revenue recognition criteria have been met for that element. Revenue for annual software subscriptions is recognized ratably over the length of the software subscription. Certain contracts for the sale of
telephone systems acquired with Vertical Networks in September 2004 were determined to be bundled with software subscriptions with lengths of up to five years from the date of acquisition. The revenue and cost of sales of the systems under these
contracts have been deferred and will be amortized ratably over the length of the associated software subscription, as the Company does not have VSOE for these subscription agreements.

##### Table of Contents

Due to the lengthy period of time over which we amortize the revenue and cost of goods sold related to
these systems, the revenue and cost of goods sold we report in any one period excludes most of the revenue and cost of goods sold relating to shipments in that period and includes revenue and costs of goods sold relating to shipments made in prior
periods. As a result, our reported revenue and costs of good sold may not necessarily be indicative of our ability to generate customer orders in a particular period. The difference between reported revenue and costs of goods sold and customer
orders in any period could be either positive or negative, and cannot be reliably predicted from period to period. The following tables demonstrate this effect by showing the amount of revenue, cost of goods sold and gross profit from systems
shipped during the three months ended December 31, 2006 and 2005 that was deferred at each quarter end (in thousands).

As a result of the significant revenue and cost of goods sold deferral related to current period
shipments of systems, the revenue and cost of goods sold reflected in our Condensed Consolidated Financial Statements may not be indicative of our ability to generate sales of our product into the marketplace in the current period. Likewise,
recognition in the current or a future period of revenue and cost of goods sold related to shipments of systems that occurred in prior years may cause the impression in the future that we are generating a higher volume of sales of our telephone
systems into the market in that period than is the case.

Revenue from time and material service contracts is recognized as the services
are provided. Revenue from fixed price, long-term service or development contracts is recognized over the contract term, using a proportional performance method, based on the percentage of services that are provided during the period compared with
the total estimated services to be provided over the entire contract. Losses on fixed price contracts are recognized during the period in which the loss first becomes apparent.

Warranty

In most cases, we provide a one-year limited warranty to our customers, including repair or
replacement of defective equipment. For certain product lines and customers, we offer longer warranty periods or extended warranties. Our contract manufacturing partners are responsible for the first year of the warranty repair work. We provide for
the estimated cost of product warranties at the time the revenue is recognized. We calculate our warranty liability based on historical product return rates and estimated average repair costs. While we engage in various product quality programs and
processes, our warranty obligation may be affected by product failure rates and the ability of our contract manufacturers to satisfy warranty claims. The outcome of these items could differ from our estimates and revisions to the warranty estimates
could be required.

Accounts Receivable

We provide allowances for doubtful accounts for estimated losses from the inability of our customers to satisfy their accounts as originally contemplated at the time of sale. We calculate these allowances based on the detailed review of
certain individual customer accounts, historical collection rates and our estimation of the overall economic conditions affecting our customer base. If the financial condition of our customers were to deteriorate, resulting in an impairment of their
ability to make payments, additional allowances may be required.

We also provide reserves for returns and sales incentives to reduce
revenue and accounts receivable for product returns and other credits we may grant to customers. Such reserves are recorded at the time of sale and are calculated based on the historical information (such as rates of product returns) and the
specific terms of sales programs, taking into account any other known information about likely customer behavior. If actual customer behavior differs from our expectations, additional reserves may be required. Also, if we determine that we can no
longer accurately estimate amounts for returns and sales incentives, we would not be able recognize revenue until the customers exercise their rights, or such rights lapse, whichever is later.

Inventory

We measure our inventories at lower of cost or
market. For those items that are manufactured by our contract manufacturers, cost is determined using standards that we believe approximate the first-in, first-out (FIFO) method. We also provide allowances for excess and obsolete
inventory equal to the difference between the cost of our inventory and the estimated market value based upon assumptions about product life cycles, product demand and market conditions. If actual product life cycles, product demand or market
conditions are less favorable than those projected by management, additional inventory allowances or write-downs may be required.

Long-lived Assets,
including Goodwill and Other Intangibles

Statement of Financial Accounting Standards (SFAS) No. 144, Accounting for
the Impairment or Disposal of Long-Lived Assets (SFAS No. 144) establishes a single accounting model for long-lived assets to be disposed of by sale. For long-lived assets that are held for use, when circumstances suggest that
there may be an impairment, we compare the forecasted undiscounted net cash flows to the carrying amount. If the long-lived asset is determined to be unable to recover the carrying amount, then it is written down to fair value. A considerable amount
of judgment is required in calculating this impairment charge, principally in determining financial forecasts. Unanticipated changes in market conditions could have a material impact on our projected cash flows. Differences in actual cash flows as
compared to the projected cash flows could require us to record an impairment.

SFAS No. 142, Goodwill and Other Intangible
Assets includes requirements to test goodwill and indefinite lived intangible assets for impairment rather than amortize them. Goodwill and other indefinite lived intangible assets must be tested for impairment on at least an annual basis. Our
goodwill resulting from our acquisitions of Vertical Networks, Comdial and Vodavi will be tested annually. Although the goodwill was deemed to not be impaired when it was tested in 2006, there can be no assurances that subsequent reviews will not
result in material impairment charges. A considerable amount of judgment is required in calculating this impairment analysis, principally in determining discount rates, financial forecasts and allocation methodology. Unanticipated changes in market
conditions could have a material impact on our projected cash flows. Differences in actual cash flows as compared to the projected discounted cash flows could require us to record an impairment loss.

Summary

The following is a summary of the areas that
management believes are important in understanding the results of the fiscal quarter and six months ended December 31, 2006. This summary is not a substitute for the detail provided in the following pages or for the condensed consolidated
financial statements and notes that appear elsewhere in this document.

Revenues

We derive revenues primarily from sales of our hardware and software products. The timing and amount of our net revenues has been, and is expected to
continue to be, influenced by a number of factors, including the following:



| |  |  | Product design, including our hardware, software and our bundled hardware and services where applicable;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | The demand for our current products;
| | - |  | ------------------------------------



| |  |  | Acquisitions made by us, such as the acquisitions of the assets of Vertical Networks, Comdial and Vodavi;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | The length of our sales cycle; and
| | - |  | ----------------------------------



| |  |  | Budgeting cycles of our customers.

Cost of Sales

Cost of sales is generally comprised of materials, manufacturing, shipping and repair of our products. Prior to the acquisitions of Vertical Networks, Comdial and Vodavi, cost of sales consisted primarily of materials for a limited amount
of shrink wrap product including software CDs and manuals and also small amounts of amortization of purchased technology. As a result of the acquisition of Vertical Networks, Comdial and Vodavi, cost of sales increased substantially due to the
hardware costs associated with sales of the InstantOffice and Comdial product lines and due to additional amortization of technology-based intangible assets associated with the acquisitions. Cost of sales also includes royalties paid to third
parties.

Operating Expenses

Our operating expenses
are comprised of:



| |  |  | Sales and marketing costs, which consist primarily of salaries and employee benefits for sales and marketing employees, travel, advertising, tradeshows and various
other marketing programs;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Product development costs, which consist primarily of salaries and employee benefits for engineering and technical personnel;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | General and administrative expenses, which generally represent salaries and employee benefits costs of executive, administrative, operations, finance, human
resource and IT personnel, as well as professional fees, insurance costs, consulting fees and administrative expenses;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Stock-based, non-cash compensation expense; and
| | - |  | -----------------------------------------------



| |  |  | Amortization of intangible assets acquired from Vertical Networks, Comdial and Vodavi.

Results of Operations

Net Revenue

Net revenue was $18.1 million and $34.0 million for the three and six months ended December 31, 2006, respectively, representing an increase of
11% and 30%, from $16.3 million and $26.2 million for the same fiscal periods from prior year. The increase in net revenue is primarily attributable to the acquisitions of Comdial, which was completed on September 28, 2005 and the
acquisition of Vodavi, which was completed on December 1, 2006.

We distribute our products both domestically and internationally.
International product revenue was $0.6 million, or 4% of total revenue, for the three months ended December 31, 2006 and $0.7 million, or 4% of total revenue, for the three months ended December 31, 2006. International product
revenue for the six months ended December 31, 2006 was $1.0 million, or 6% of total revenue, and $0.9 million, or 3% of total revenue, for the six months ended December 31, 2005.

Gross profit as a percentage of revenue remained the same for the quarters ended December 31, 2006 and
December 31, 2005. The decrease in gross profit as a percentage of net revenue for the six months ended December 31, 2006, compared to the corresponding period ended December 31, 2005, was due primarily to the addition of revenue and
associated cost of sales from the acquisitions of Comdial and Vodavi, which sales have a lower margin compared to other of our product lines.

Sales and Marketing

For the three months ended December 31, 2006, sales and marketing expenses decreased by $1.1 million, and their costs as a percentage of revenue
decreased from 29% to 20% compared with the corresponding period in 2005. For the six months ended December 31, 2006, sales and marketing expenses decreased by $1.4 million, and their costs as a percentage of revenue decreased from 33% to 21%
compared with the corresponding period in 2005. The decrease in sales and marketing expenses in aggregate dollars for the three and six months ended December 31, 2006 compared to the corresponding periods ended December 31, 2005 was due
primarily to decreased payroll expenses as a result of cost reductions from consolidation efforts related to the Comdial acquisition offset by the increase in sales support from the Vodavi acquisition. The Company employed 74 sales and marketing
personnel throughout the quarter ended December 31, 2006 except that for the one month of December 2006, sales and marketing added 43 additional personnel due to the Vodavi acquisition. The Company employed 121 sales and marketing personnel
throughout the quarter ended December 31, 2005.

Product Development

For the three months ended December 31, 2006, product development expenses increased by $0.1 million, whereas their costs as a percentage of revenue
decreased from 18% to 17% compared with the corresponding period in 2005. For the six months ended December 31, 2006, product development expense increased by $0.2 million, whereas their costs decreased as a percentage of revenue from 23% to
18%. The increase in product development expenses in aggregate dollars for the three and six months ended December 31, 2006 compared to the corresponding periods ended December 31, 2005 was due primarily to additional costs related to our
next generation product development efforts offset by cost reductions from consolidation efforts related to the Comdial acquisition. The Company also incurred additional expenses for the one month of December 2006 due to the Vodavi acquisition. The
Company employed 73 product development personnel throughout the quarter ended December 31, 2006 except that for the one month of December 2006, product development added 23 personnel due to the Vodavi acquisition. The Company employed 84
product development personnel throughout the quarter ended December 31, 2005.

General and Administrative

For the three months ended December 31, 2006, general and administrative expense decreased $0.9 million, and their costs as a percentage of revenue
decreased from 30% to 22% as compared with the same period ended December 31, 2005. This is primarily a result of elimination of redundant overhead operations related to the acquisition of Comdial offset by the additional expenses related to
the Vodavi acquisition. For the six months ended December 31, 2006, general and administrative expense increased $0.7 million, whereas their costs as a percentage of revenue decreased from 28% to 24% as compared with the same period ended
December 31, 2005. The increase in general and administrative expenses for the six month period ended December 31, 2006 compared to the same period ended December 31, 2005, was primarily driven by the additional expenses related to
the Vodavi acquisition and a 45% increase in liquidated damages The Company employed 44 general and administrative personnel throughout the quarter ended December 31, 2006 except that for the one month of December 2006, general and
administrative personnel increased by 27 due to the Vodavi acquisition. The Company employed 37 general and administrative personnel throughout the quarter ended December 31, 2005.

General and Administrative expense also includes liquidated damages that we are accruing related to the
2004 Stock Purchase Agreement, the 2005 Stock Purchase Agreement and the 2006 Securities Purchase Agreement. Total liquidated damages recorded for the three and six months ended December 31, 2006 was $431,000 and $1.0 million, respectively.
Total liquidated damages recorded for the three and six months ended December 31, 2005 was $550,000.

Operating Loss

For the quarter ended December 31, 2006, our operating loss decreased $2.6 million, or 52%, to ($2.3) million on revenue of $18.1 million, from an
operating loss of ($4.9) million on revenue of $16.3 million for the quarter of December 31, 2005. This was due to an increase in gross profit of $0.8 million and $1.8 million decrease in operating expense. For the six months ended
December 31, 2006, our operating loss decreased $2.9 million, or 35%, to ($5.3) million on revenue of $34.0 million, from an operating loss of ($8.2) million on revenue of $26.2 million for the six months ended December 31, 2005. The
factors affecting this decrease in operating loss were a $2.7 million increase in gross profit and $0.2 million decrease in operating expense, primarily a result of the revenue added from the Vodavi acquisition and the expected decline in overall
operating expenses from consolidation efforts related to the acquisition of the Comdial operations.

Included in the operating loss are
non-cash compensation expense related to stock option grants of $1.0 million and $2.0 million in the three and six months ended December 31, 2006, respectively, compared with $1.0 million and $2.2 million in the three and six months ended
December 31, 2005, respectively, and depreciation and amortization (for other than the acquired intangibles) expense of $0.4 million and $0.7 million in the three and six months ended December 31, 2006, respectively, compared with $0.4
million and $0.6 million in the three and six months ended December 31, 2005, respectively.

As mentioned above under the caption
Revenue Recognition, we defer a significant portion of the revenue and cost of goods sold related to current period shipments while recognizing revenue and cost of goods sold from shipments in prior periods.

Interest Expense

Interest expense for the three and
six months ended December 31, 2006 was $1.2 million and $1.4 million, respectively, compared with $0.3 million for the three and six months ended December 31, 2005. The increase in interest expense relates to debt instruments incurred in
order to finance the acquisitions of Comdial and Vodavi.

Income Tax Expense

While we incurred net losses in the three and six month periods ended December 31, 2006 and 2005, we recorded a deferred tax provision associated
with the goodwill created and intangibles acquired with the Vertical Networks and Comdial acquisitions. The effective tax rate utilized for the provision was 40.0%.

Financial Condition, Liquidity And Capital Resources

Despite the overall decrease in our operating
expenses as a percentage of revenue, we will be required to carefully manage our expenses to maximize our liquidity. We are continuing to review our integration plans and expect to continue to reduce expenses as we reduce redundancies and streamline
our operations.

Net cash flows used in operating activities were $3.5 million during the six months ended
December 31, 2006. The cash used in operating activities was due primarily to a net loss of $7.0 million, offset by depreciation and amortization of $1.6 million and $2.0 million relating to a non-cash compensation charge.

Working capital, consisting of total current assets minus current liabilities, was $8.9 million at December 31, 2006. This compared to a
working capital deficit of $6.8 million at June 30, 2006, representing an increase of $15.9 million. The increase in working capital at December 31, 2006 is a result of the cash proceeds related to the financing for the
acquisition of Vodavi.

##### Table of Contents

We have incurred losses and negative or minimal positive cash flows from operations in every fiscal
period since 1996 and have an accumulated deficit, including non-cash equity charges, of $82.4 million as of December 31, 2006. For the three months ended December 31, 2006 we incurred a net loss of approximately $3.7 million,
which includes negative cash flows from operations of approximately $3.5 million. Our management expects that operating losses will continue in the near future. As of June 30, 2006, our cash resources were not adequate to meet our
short-term requirements through the end of the 2007 fiscal year. Therefore in October, 2006, we obtained binding, non-cancellable commitments from certain of our investors and our chief executive officer to fund our operations, up to $5.0 million,
through September, 2007. In addition we have completed the debt and equity financings in conjunction with our acquisition of Vodavi (see Notes 6 and 8 to the Condensed Consolidated Financial Statements). As a result, we anticipate that we will meet
our anticipated cash requirements for the next twelve months. A change in circumstance, such as a reduction in the demand for our products could necessitate that we seek additional debt or equity capital or take actions to reduce our operating costs
to levels that can be supported by our available cash. Such additional financings may not be available on terms acceptable to us, or at all, and may significantly affect our stockholders, including for example, by substantially diluting their
ownership interest.

Item 3.  QUANTITATIVE AND QUALITAT
IVE DISCLOSURES ABOUT MARKET RISK

Market Risk.During the normal course of business we are routinely subjected to a
variety of market risks, examples of which include, but are not limited to, interest rate movements and collectability of accounts receivable. We currently assess these risks and have established policies and practices to protect against the adverse
effects of these and other potential exposures. Although we do not anticipate any material losses in these risk areas, no assurances can be made that material losses will not be incurred in these areas in the future.

Interest Rate Risk.We may be exposed to interest rate risk on certain of our cash equivalents. The value of certain of our investments may be adversely affected
in a rising interest rate investment environment. Although we do not anticipate any material losses from such a movement in interest rates, no assurances can be made that material losses will not be incurred in the future.

Item 4.  CONT
ROLS AND PROCEDURES

Disclosure Controls and Procedures are defined in Exchange Act Rules 13a-15(e) and 15d-15(e) as
the controls and procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the
time period specified by the SECs rules and forms. Disclosure Controls and Procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files
or submits under the Exchange Act is accumulated and communicated to the issuers management, including our principle executive and principal financial officers to all timely decisions regarding disclosure.

We have endeavored to design our Disclosure Controls and Procedures and Internal Controls Over Financial Reporting to provide reasonable assurances that their objectives
will be met. However, management and our audit committee do not expect that our disclosure controls or internal controls over financial reporting will prevent all errors or all instances of fraud or a material weakness. A control system, no matter
how well designed and operated, can provide only reasonable, not absolute, assurance that the control

##### Table of Contents

systems objectives will be met. All control systems are subject to inherent limitations, such as resource constraints, the possibility of human error,
lack of knowledge or awareness, and the possibility of intentional circumvention of these controls. Furthermore, the design of any control system is based, in part, upon assumptions about the likelihood of future events, which assumptions may
ultimately prove to be incorrect. As a result, we cannot assure you our control system will detect every error or instance of fraudulent conduct, including an error or instance of fraudulent conduct that could have a material adverse impact on our
operations or results.

Evaluation of Disclosure Controls and Procedures.

As of December 31, 2006, our management, with the participation of our Audit Committee, Chief Executive Officer and Chief Financial Officer,
evaluated the effectiveness of our Disclosure Controls and Procedures. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2006, the design and operation of these disclosure
controls and procedures were effective during the quarter ended December 31, 2006. We believe that we have adequate staffing in our finance group with the appropriate level of experience to effectively control the increased level of transaction
activity, address the complex accounting matters and manage the increased financial reporting complexities resulting from the acquisitions of Vertical Networks, Comdial and Vodavi and the associated integration activities.

We continue to evaluate our resources for addressing our financial reporting and making appropriate changes to provide sufficient resources and time to
prepare and file periodic reports within the time periods specified in the SECs rules and regulations and provide for reviews by our management, our audit committee and our board of directors. Our Chief Executive Officer and Chief Financial
Officer continue to review our personnel, resources and disclosure controls and procedures.

Changes in Internal Control Over Financial Reporting.

There were no changes in the Companys internal control over financial reporting during the quarter ended December 31, 2006,
that materially affected, or are reasonably likely to materially affect, the Companys internal control over financial reporting.

PART II  OTHER IN
FORMATION

Item 1.  Legal Proce
edings

From time to time we are involved in various claims and other legal proceedings which arise in the
normal course of our business. Such matters are subject to many uncertainties and outcomes that are not predictable. However, based on the information available to us and after discussions with legal counsel, we do not believe any such proceedings
will have a material adverse effect on our business, results of operations, financial position or liquidity. We cannot provide assurance, however that damages that result in a material adverse effect on our financial position or results of
operations will be not be imposed in these matters.

Item 1A.  Risk
 Factors

We caution you that the following important factors, among others, in the future could cause our
actual results to differ materially from those expressed in forward-looking statements made by, or on behalf of, us in filings with the SEC, press releases, communications with investors and oral statements. Any or all of our forward-looking
statements in this Form 10-Q, and in any other public statements we make may turn out to be wrong. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. Many factors mentioned in the discussion
below are important in determining future results. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise. You are advised, however, to consult any further
disclosures we make in our reports filed with the SEC.

We have a history of losses and expect to incur future losses.

We had operating losses for the quarter ended December 31, 2006 and in each of the last 12 fiscal years. We also had negative cash flow from
operating activities in the quarter ended December 31, 2006 and had negative cash flow in seven out of the last eleven fiscal years. If our revenues do not increase significantly, without a corresponding decrease in expenses, we may never
achieve profitability, on a sustained basis or at all, or generate positive cash flow in the future. In that case our business will fail. We expect to incur significant future operating losses and negative cash flows. Vertical Networks, Inc. also
incurred operating losses in each of their last three fiscal years prior to being acquired by us. Comdials revenues and operating results have experienced fluctuations in the past and may cause our revenues and operating results to vary in the
future. Comdials revenues and operating results have varied significantly in the past due to various factors, including changes in market acceptance of Comdials services, regulatory changes that may affect the marketability of
Comdials services, budgetary cycles of Comdials principal clients, the mix and timing of client projects, and one-time nonrecurring and unusual charges. As a result, the operations acquired from Vertical Networks and Comdial may not
consistently generate profits or positive cash flow, which would likely have a material negative impact on our business, our financial condition and our results of operations.

We will need additional working capital, the lack of which would likely have a significant negative impact on our current level of operations.

The Comdial acquisition consumed significant amounts of working capital and the Comdial Assets were acquired with limited working capital. As a result,
we may require additional capital in the future to fund our operations, finance investments in product development and corporate infrastructure, expand in our various geographic markets and respond to competitive pressures and opportunities for
growth. Failure to obtain additional funding would prevent us from making expenditures that are needed to allow us to grow or maintain our operations. We cannot assure you that additional financing will be available on favorable terms, or at all. If
funds are not available when required for our working capital needs or other transactions, our ability to carry out our business plan will be adversely affected, and we may be required to scale back our growth and operations to reflect the extent of
available funding. If we are able to arrange for additional credit facilities from lenders, the debt instruments are likely to include limitations on our ability to incur other indebtedness, to pay dividends, to create liens, to sell or purchase our
capital stock, to sell assets or to make acquisitions or enter into other transactions. Such restrictions may adversely affect our ability to finance our future operations or capital needs or to engage in other business activities, including,
without limitation, acquisitions of additional businesses. We are already subject to such restrictions under the stock purchase agreement executed on September 28, 2004 (the 2004 Stock Purchase Agreement), the stock purchase
agreement executed on September 28, 2005 (the 2005 Stock Purchase Agreement), securities purchase agreement executed on February 9, 2006 (the 2006 Securities Purchase Agreement), the Credit Agreement executed on
October 18, 2006 and the Securities Purchase Agreement, executed on October 18, 2006, as amended and restated. If we raise additional funds by issuing equity or convertible debt securities, the percentage ownership of our stockholders will
be reduced. These securities would likely have rights, preferences or privileges senior to those of our common stockholders. The inability to obtain substantial increases in our working capital resources will likely have a material negative impact
on our business, our financial condition and our results of operations.

Our former and current independent registered public accounting firms have
previously indicated that we have certain material weaknesses with our internal controls and as a result, our internal controls over financial reporting may not be effective.

##### Table of Contents

Our former independent registered public accounting firm, KPMG LLP (KPMG), advised our
management and our audit committee that, in connection with its review of our financial statements for the three and six month periods ended December 31, 2004, KPMG noted certain matters involving internal control and its operation that it
considered to be a material weakness that constituted reportable conditions under standards established by the American Institute of Certified Public Accountants. Reportable conditions are matters coming to an independent registered public
accounting firms attention that, in its judgment, relate to significant deficiencies in the design or operation of internal control and could adversely affect the organizations ability to record, process, summarize, and report financial
data consistent with the assertions of management in the financial statements. KPMG advised our management and our audit committee that it considered the following to constitute reportable conditions related to internal control and their operations:
we did not have adequate staffing in our finance group with the appropriate level of experience to effectively control the increased level of transaction activity, address the complex accounting matters and manage the increased financial reporting
complexities resulting from the acquisition of Vertical Networks and the associated integration activities.

Our current independent
registered public accounting firm, Vitale Caturano and Company Ltd. (VCC) advised our management and our audit committee that, in connection with their audit of our financial statements for the year ended June 30, 2005, VCC noted
certain matters involving internal control and its operation that it considered to be a material weakness that constituted reportable conditions under the standards of the Public Accounting Oversight Board (PCAOB). VCC advised our management and our
audit committee that it considered the following to constitute a material weakness in internal control and operations: we did not have adequate staffing in our accounting and finance group with the appropriate level of experience to effectively
accomplish timely and accurate closings, control the increased level of transaction activity, address the complex accounting matters and manage the increased financial reporting complexities resulting from recent acquisitions.

We are also in the preliminary stages of preparing for our report on internal controls over financial reporting, which must be filed with the annual
report for our fiscal year ending June 30, 2008. The effectiveness of our controls and procedures may be limited by a variety of risks, including, without limitation, faulty human judgment and simple errors, omissions, or mistakes; the
collusion of two or more people or inappropriate management override of procedures; and imprecision in estimating and judging cost-benefit relationships in designing controls. At this point in the process, it is not possible to ascertain whether
this report will disclose any significant deficiencies or material weaknesses in our internal controls over financial reporting or even whether we will be able to conclude, after such analysis, that our internal controls are effective; however, our
recent failure to timely file certain Exchange Act reports, as well as the matters discussed above, resulted in our auditor determining that we have a material weakness in our internal controls system. Upon a determination that we have such a
material weakness, we will be required to report that our internal controls over financial accounting are not effective. If we fail to have effective internal controls and procedures for financial reporting in place, we could be unable to provide
timely and reliable financial information.

We have not timely filed several of our periodic reports under the Exchange Act and may fail to timely file
periodic Exchange Act reports in the future.

We failed to timely file our Quarterly Reports on Form 10-Q for the quarters ended
September 30, 2004, December 31, 2004, and March 31, 2005, our Annual Report on Form 10-K for the year ended June 30, 2006, an amendment to our Current Report on Form 8-K originally filed September 29, 2004 to disclose
certain financial data in connection with our acquisition of Vertical Networks, and our Current Report on Form 8-K relating to the execution of an office lease dated July 6, 2005. We filed the Quarterly Report for the quarter ended
September 30, 2004 on January 25, 2005, filed the Quarterly Report for the quarter ended December 31, 2004 on April 1, 2005, filed the Quarterly Report for the quarter ended March 31, 2005 on June 3, 2005, filed the
Annual Report on Form 10-K for the year ended June 30, 2006 on October 16, 2006 and amended it on October 31, 2006 to include Part III information, filed our amendment to our Form 8-K on April 20, 2005, and our 8-K on
July 14, 2005. If we cannot timely file our Exchange Act reports in the future, we will remain ineligible to register our securities on Form S-3 until 12 months after the last late filed Exchange Act report, and ineligible to qualify for the
safe harbor provisions for resale of restricted securities under Rule 144 of the Exchange Act. Inability to register securities on Form S-3 or sell restricted securities under the safe harbor provisions of Rule 144 limits the liquidity of our
securities and restricts the market for our securities.

In addition, failure to remain current in our Exchange Act reporting requirements
in the future may in the future result in our common stock being de-listed from the OTC Bulletin Board and adversely affect our ability to list our common stock on a national exchange or the NASDAQ Stock Market in the future. If our common stock
were to be de-listed from the OTC Bulletin Board, the market for our common stock would become severely restricted and holders of our common stock may be unable to sell their shares. We have agreed in the 2004 and 2005 Stock Purchase Agreements and
the 2006 Securities Purchase Agreement to seek a listing of our common stock on a national exchange or the NASDAQ Stock Market. If we are unable to list our securities on a national exchange or the NASDAQ Stock Market because we have failed to
remain current in our Exchange Act reporting requirements, we may be subject to claims by M/C Venture Partners for indemnification, liability for breach of contract or other common law remedies.

If we do not resume trading on a national exchange or the NASDAQ Stock Market and if we are de-listed from the OTC Bulletin Board, trading in our common
stock may only be conducted based on trading information referenced on the Pink Sheets. Being quoted on the Pink Sheets could damage our general business reputation, could impair our ability to raise additional capital and
cause the market price for our shares to fall. Securities quoting on the Pink Sheets tend to be less liquid and subject to volatile stock prices.

Our stockholders could be adversely affected if M/C Venture Partners use their influence in a manner adverse to our
stockholders interests.

As of December 31, 2006, M/C Venture Partners beneficially owned approximately 34.5% of our common
stock. Based upon its substantial voting power and their director rights, M/C Venture Partners is in a position to exert substantial influence over matters submitted to our stockholders for approval and our management and affairs, including the
election and removal of directors and any merger, consolidation or sale of all or substantially all of our assets. In addition, M/C Venture Partners currently maintains the contractual right to nominate two members to our seven member board of
directors and has a shared right with our board of directors to nominate an additional two members. Accordingly, such concentration of ownership and ability to appoint members to our board may have the effect of delaying, deterring or preventing a
change in control of our company, impeding a merger, consolidation, takeover or other business combination or discouraging a potential acquirer from making a tender offer or otherwise attempting to take control of our company, which in turn could
have a negative effect on the market price of our stock. These actions could also be adverse to our other stockholders interests.

Because we
failed to cause the registration statement filed on December 6, 2005 to be declared effective in accordance with the timetables set forth in 2005 Stock Purchase Agreement and the 2004 Stock Purchase Agreement, as amended, we are subject to
liquidated damages or liability for breach of contract.

We are obligated to pay approximately $2.2 million in liquidated damages to
the 2005 Investors and 204 Investors. Pursuant to the 2005 Stock Purchase Agreement and the 2004 Stock Purchase Agreement, as amended, we agreed to register the shares of our common stock issued to the 2005 Investors and the 2004 Investors for
resale under the Securities Act of 1933. We agreed to file a registration statement covering these shares no later than December 12, 2005. We filed this registration statement relating to these shares of common stock, among others, on
December 6, 2005 (the Filing Date). We further agreed to use our best efforts to cause the registration statement to become effective in certain events but no later than 90 days after the Filing Date (referred to as the
Required Effective date). We are liable for liquidated damages to each investor as a result of the Effectiveness Default.

We
must pay as liquidated damages to the 2005 Investors, and the 2004 Investors for each 30-day period of the effectiveness default, an amount in cash equal to 1% of the aggregate purchase price paid by the 2005 Investor or 2004 Investor as the case
may be, pursuant to the 2005 Stock Purchase Agreement or the 2004 Stock Purchase Agreement, provided that in no event will the aggregate amount of cash to be paid as liquidated damages exceed 9% of the aggregate purchase price paid by any respective
2005 Investor or 2004 Investor. Currently, we have not paid any liquidated damages to any 2005 Investor or any 2004 Investor.

Should we be
required to make payment of these liquidated damages, it will likely have a material adverse effect on our liquidity, our financial position and our results of operations, particularly if we became obligated to make payment in full of all liquidated
damages potentially due and payable under these agreements.

Because we failed to file a registration statement in accordance with the timetable set
forth in the 2006 Securities Purchase Agreement, we are subject to liquidated damages and possibly liability for breach of contract.

We are obligated to pay $450,000 in liquidated damages to the Series D Investors. Pursuant to the 2006 Securities Purchase Agreement, we have agreed to register the shares of common stock issuable upon conversion of the Series D Convertible
Preferred Stock (the Series D Preferred Stock) and upon exercise of the warrants for resale by the 2006 investors under the Securities Act. We agreed to file with the SEC a registration statement with respect to the Series D Preferred Stock and
warrants no later than March 27, 2006 (the 2006 Filing Date), and to use our best efforts to cause the registration statement to become effective on or before the date that is the earlier of (1) in the event of no review by the
SEC, within five days of being informed by the SEC that the SEC has decided not to review the Registration Statement, but in no event later than 30 days after the 2006 Filing Date, (2) in the event of a review by the SEC, within five days of
being informed by the SEC that the SEC has no further comments on such registration statement, but in no event later than 90 days after the 2006 Filing Date (the earlier of (1) and (2), the 2006 Required Effective Date).

Because we failed to file the registration statement by the 2006 Filing Date, we are obligated to pay as liquidated damages to the Series D Investors,
for each 30-day period of a 2006 Registration Default, an amount in cash equal to 1% of the aggregate purchase price paid by the 2006 Investor pursuant to the 2006 Stock Purchase Agreement; provided that in no event will the aggregate amount of cash
to be paid as liquidated damages exceed 9% of the aggregate purchase price paid by such Series D Investor. We must pay the liquidated damages on the business day following the 2006 Filing Default, and each 30th day thereafter, until the registration
statement has been filed with the SEC. Currently, we have not paid any liquidated damages to any Series D Investor.

In addition to
liquidated damages pursuant to the 2004 and 2005 Stock Purchase Agreements, our obligations to pay these liquidated damages will likely have a material adverse effect on our liquidity, our financial position and our results of operations,
particularly if we become obligated to make payment in full of all liquidated damages potentially due and payable under these agreements.

Restrictive covenants in the 2004 and 2005 Stock Purchase Agreement, the 2006 Securities Purchase Agreement and the
Series E Securities Purchase Agreement may limit our ability to pursue our business strategies.

We have agreed under the terms of the
2004 and 2005 Stock Purchase Agreements and the 2006 Securities Purchase Agreement that we will not, without the prior consent of M/C Venture Partners, (1) enter into a transaction involving a change in control of our company; (2) incur
indebtedness in excess of $3.0 million, subject to specified exceptions; (3) create any security with an equity component unless that security is junior to the common stock; (4) issue any equity securities; (5) transfer our
intellectual property; (6) repurchase, redeem or pay dividends on any shares of capital stock (subject to limited exceptions); (7) grant stock options that are not authorized by a vote of the board of directors or its compensation
committee; (8) liquidate or dissolve; (9) change the size of our board of directors; (10) amend our Certificate of Incorporation or bylaws; (11) change the nature of the Companys business; (12) alter the voting rights
of shares of our capital stock in a disparate manner; or (13) take any action which would cause an adjustment to the exercise price or number of shares to be delivered under Section 8 of the warrants issued to the 2006 Investors.

If we do not comply with these covenants, we could be subject to claims for indemnification, liability for breach of contract and other common law
remedies. Compliance with these covenants may limit our ability to pursue growth opportunities or address concerns with our operations. Our ability to comply with these covenants and restrictions may be affected by changes in the economic or
business conditions or events beyond our control.

Restrictive covenants in the Credit Agreement may limit our ability to pursue our business
strategies.

Under the terms of the Credit Agreement, we are not permitted to take certain actions without the prior written consent of
Investment Manager and Lender, including, without limitation, the following:



| |  |  | mortgage, assign, pledge, transfer or otherwise permit any lien, charge, security interest encumbrance or judgment to exist on any of the collateral pledged under
the Credit Agreement and related Security Agreement or our other assets, whether now owned or acquired later, except for certain permitted encumbrances;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | incur or create any indebtedness, except for certain permitted indebtedness;
| | - |  | ----------------------------------------------------------------------------



| |  |  | sell, lease, assign, transfer or otherwise dispose of (i) any collateral pledged under the Credit Agreement and Security Agreement, except for the sale of
inventory and equipment in the ordinary course of our business, or (ii) all or any substantial part of our assets that do not constitute collateral. We, however, may sell obsolete or surplus equipment if certain conditions specified in the
Credit Agreement are met;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | merge or consolidate with any other entity, except as permitted by the Credit Agreement, change our structure or organizational form, reincorporate or reorganize in
a new jurisdiction, or enter into or engage in any operation or activity materially different from that presently being conducted by our company;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | pay any dividend or distribution of any kind on, or purchase, acquire, redeem or retire, any of its equity interests;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | create any new subsidiary (other than to consummate certain acquisitions), make any advance or loan to, or any investment in any firm, entity, person or
corporation, or acquire all or substantially all of the assets of, or any capital stock or equity interests in any firm, entity or corporation, except our current investments in existing subsidiaries;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | enter into any transaction with any shareholder, officer, director, direct or indirect parent, direct or indirect subsidiary or other related person, except for

| |  |  | make certain specified restricted payments described in the Credit Agreement;
| | - |  | -----------------------------------------------------------------------------



| |  |  | use proceeds of funds received under the Credit Agreement in any manner prohibited by the Credit Agreement;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | cause any encumbrance or restriction on the ability of our subsidiaries to make certain payments to us;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | engage in any business other than certain specified businesses;
| | - |  | ---------------------------------------------------------------



| |  |  | change or amend the terms of any of our subordinated debt for certain specified purposes; or
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | other customer restrictions.
| | - |  | ----------------------------

If we
do not comply with these covenants, we will be subject to claims for indemnification, liability for breach of contract and other common law remedies. Compliance with these covenants may limit our ability to pursue growth opportunities or address
concerns with our operations. Our ability to comply with these covenants and restrictions may be affected by changes in the economic or business conditions or events beyond our control.

Certain restrictions in the certificates of designations for the Series D Preferred Stock and the Series E Preferred Stock may limit our ability to carry out our business plan.



32



---

##### Table of Contents

Under the terms of the certificates of designation for our Series D Preferred Stock and our Series E
Preferred Stock, we are not permitted to take certain actions without the prior written consent of holders of a majority of the outstanding Series D Preferred Stock and Series E Preferred Stock including, without limitation, the following:



| |  |  | amend, alter or repeal any right, preference or privilege of the Series D Preferred Stock or the Series E Preferred Stock, respectively, any provision of our
certificate of incorporation or bylaws, or any document executed in connection with the Series E Financing;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | create any additional class or series of shares of stock, or any convertible debt securities, unless it is subordinate to the common stock as to dividends and
distribution of assets on the liquidation, dissolution or winding up of our company;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | issue or agree to issue any equity security or any security that is convertible, exercisable or exchangeable for or into any equity security (including convertible
debt securities) except certain permitted issuances;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | change the number of shares of our capital stock reserved for grants or issuance to employees, directors, contractors or consultants under our equity incentive
plans;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | approve or engage in any transaction for the acquisition of any other person, entity or organization, the business or substantially all of the assets of any other
person, entity or organization, except the acquisition of any of our subsidiaries;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | liquidate, dissolve or wind-up our business and affairs, effect any deemed liquidation event or consent to do any of the foregoing;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | purchase or redeem, or pay any dividend or make any distribution on, any shares of our capital stock or permit any subsidiary to do any of the foregoing except for
certain permitted dividends and redemptions; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | change the number of directors constituting the size of the Board of Directors.
| | - |  | -------------------------------------------------------------------------------

These restrictions may limit our ability to raise capital in the future or may limit our operations while they are in effect. If we take one of the above
actions and fail to obtain the required consent of the respective holders of our Series D Preferred Stock and Series E Preferred Stock, it may result in the prohibited transactions being voided and we may be liable for breach of contract and other
common law remedies. Additionally, we may damage our relationship with certain of our stockholders whose participation in future equity financings may be required for us to continue operations or consummate key transactions necessary for the success
of our business. If these relationships are irreparably damaged, we may be unable to consummate certain transactions that may be necessary for the operation of our business.

Failure to successfully integrate the acquired operations of Vertical Networks, Comdial and Vodavi could have a material adverse effect on our combined operations.

Our decisions to acquire the operations of Vertical Networks, Comdial and Vodavi were based in part, on our belief in the growth opportunities and cost
savings we hope to achieve from the integration of those operations into our operations and our plans to expand our product offerings to our customers and future customers. Our success in realizing these and other anticipated benefits could be
adversely affected by a number of factors, many of which are outside our control. These challenges include the timely, efficient and successful execution of a number of post-acquisition events, including:



| |  |  | integrating the operations and technologies of the three companies;
| | - |  | -------------------------------------------------------------------



| |  |  | retaining and assimilating the key personnel of each company;
| | - |  | -------------------------------------------------------------



| |  |  | retaining existing customers of these companies and attracting additional customers;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | retaining strategic partners of each company and attracting new strategic partners; and
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | creating uniform standards, controls, procedures, policies and information systems.
| | - |  | -----------------------------------------------------------------------------------

The execution of these post-acquisition events will involve considerable risks and may not be successful. These risks include:



| |  |  | the potential disruption of the combined companys ongoing business and distraction of its management;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | the potential strain on our financial and managerial controls and reporting systems and procedures;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | unanticipated expenses and potential delays related to integration of the operations, technology and other resources of the two companies and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the impairment of relationships with employees, suppliers and customers as a result of the integration of personnel and any reductions in force.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------

The combined company may not succeed in addressing these risks or any other problems encountered in connection with
these acquisitions. The inability to successfully integrate our operations, technology and personnel with those of Vertical Networks, Comdial and Vodavi or any significant delay in achieving integration, could have a material adverse effect on the
combined company after the acquisition and, as a result, on the market price of our common stock.

We may experience difficulties marketing our products
following the acquisitions of Vertical Networks, Comdial and Vodavi.



33



---

##### Table of Contents

With the acquisition of Vertical Networks, we now market a significant amount of products, primarily
InstantOffice and its family of products, to several large enterprise customers, including CVS and Staples. We have little experience marketing our products to, or establishing and maintaining customer relationships with, such large enterprise
customers. If we are unable to maintain what are essentially new customers, it would likely result in a decline in sales of InstantOffice, which would likely have a material adverse effect on our ability to generate revenues. If we are unable to add
additional large enterprise customers, we may have difficulty in our efforts to increase our revenues and achieve profitability.

The
former customers of Comdial may not continue their current buying patterns following our acquisition of the Comdial Assets. Any significant delay or reduction in orders for the Comdial Products could harm the combined companys business,
financial condition and results of operations. Former customers of Comdial may defer purchasing decisions as they evaluate the likelihood of successful integration of our products with those of Comdial, and the combined companys future product
strategy, or consider purchasing products of our competitors. Former Comdial customers may also seek to modify or terminate existing agreements, or prospective customers may delay entering into new agreements or purchasing our products. In addition,
by increasing the breadth of our business, the acquisition may make it more difficult for the combined company to enter into relationships, including customer relationships, with strategic partners, some of whom may view the combined company as a
more direct competitor than either entity as an independent company.

Vodavis customers may not continue their current buying
patterns following our acquisition of the company. Any significant delay or reduction in orders for Vodavis products could harm the combined companys business, financial condition and results of operations. Former customers of Vodavi may
defer purchasing decisions as they evaluate the likelihood of successful integration of our products with those of Vodavi, and the combined companys future product strategy, or consider purchasing products of our competitors. In addition, by
increasing the breadth of our business, the acquisition may make it more difficult for the combined company to enter into relationships, including customer relationships, with strategic partners, some of whom may view the combined company as a more
direct competitor than either entity as an independent company.

Integrating our companies may divert managements attention away from our
operations.

Successful integration of our operations, products and personnel with those of Vodavi may place a significant burden on
our management and our internal resources. The diversion of management attention and any difficulties encountered in the transition and integration process could harm our business, financial condition and operating results.

If we fail to retain key employees, the benefits of the acquisitions could be diminished.

The successful acquisition of Vodavi will depend in part on the retention of key personnel. As a result of the acquisition, our employees and those of
Vodavi could experience uncertainty about their future roles within our continuing operations. This uncertainty may adversely affect our ability to attract and retain key management, sales, marketing and technical personnel. There can be no
assurance that we will be able to retain our key management, technical, sales and customer support personnel or those of Vodavi. If we fail to retain such key employees, we may not realize the anticipated benefits of the acquisition.

Our revenues are highly concentrated among a small number of customers and the loss of one of these customers would harm our business and prospects, perhaps
materially.

A significant portion of our revenues are generated by a small number of customers. If we were to lose one or more of
these customers, our revenues would decline and our business and prospects would be materially harmed. We expect that even if we are successful in developing relationships with additional customers through the acquisition of the Vodavi, or through
additional sales of our historic products, our revenues will continue to be concentrated. We cannot assure you that we will be able to retain any of our current customers or that we will be able to obtain new customers.

We do not have long-term contracts with a majority of our customers, which renders our sales channels particularly unstable.

We do not have any long-term agreements with our customers who acquire our products. Accordingly, our customers are not contractually obligated to buy
from us in the future. Our customers are not required to make minimum purchases from us or make purchases at any particular time and are free to purchase from our competitors. Also, our customers can stop purchasing our products at any time without
penalty. If our customers do not purchase our products in sufficient quantities or on a recurring basis, our business and prospects will suffer. Even if our customers are willing to purchase our products, we cannot assure you that we will be able to
sell our products at prices that are favorable to us.

We rely on others to promote and sell our products, and their failure to do so may seriously harm
our business.

We depend on distributors and resellers and system integrators to market and sell our products. If these customers do
not focus their marketing efforts on software- or server-based phone systems or focus on products competitive with our products our sales

##### Table of Contents

will be materially adversely affected. Failure of distributors, system integrators, and resellers to focus on software- or server-based phone systems may
send a negative signal to current and potential customers concerning the viability of our industry or our product offerings. We depend upon the availability of distribution outlets to market our products. Loss of these outlets will harm our ability
to broaden our brand acceptance and enhance our reputation in the market. In addition, our operating results would be adversely affected if one of our major distributors, resellers or original equipment manufacturers failed to timely and fully pay
us for the products they purchased from us for resale or integration, as the case may be.

If software- and server-based phone systems do not achieve
widespread acceptance, we may not be able to continue our operations.

The market for software- and server-based business phone systems
is relatively new and rapidly evolving. Businesses have invested substantial resources in the existing telecommunications infrastructure, including traditional private telephone systems, and may be unwilling to replace these systems in the near term
or at all. Businesses also may be reluctant to adopt computer telephony systems because of their concern about the current limitations of data networks, including the Internet. For example, end-users sometimes experience delays in receiving calls
and reduced voice quality during calls when routing calls over data networks. Moreover, businesses that begin to route calls over the same networks that currently carry only their data also may experience these problems if the networks do not have
sufficient capacity to carry all of these communications at the same time. We cannot assure you that businesses will migrate toward computer telephony systems or that computer telephony systems will gain widespread acceptance.

Rapid technological change creates a dependence on development of new products.

The market for telecommunications systems and products has been characterized by rapid technological change and continuing demand for new products and features. Accordingly, the timely introduction of new products and
product features, as well as new telecommunications applications are expected to continue to be major factors in our future success. Market needs and expectations will require us to continue to identify, develop, and sell new products and features
that keep pace with technological developments and competitive pressures. In addition, technological difficulties occasionally inherent in new products and the time necessary to stabilize new product manufacturing costs may adversely affect
operating costs. There can be no assurance that our products will achieve market acceptance, or that we will be able to continue to develop new products, technologies, and applications as required by changing market needs in the future.

Products in our Comdial and Vodavi inventories may become obsolete.

Comdial and Vodavi offer a variety of communications products which included technologies that are enhanced rapidly in todays business environment. Both companies measured their product inventories on hand at
the lower of cost or market and provided allowances for excess and obsolete inventory equal to the difference between the cost of inventory and the estimated market value based on assumptions about product life cycles, product demand and market
conditions. The technologies incorporated into our newer products are periodically modified in reaction to both customer requirements and to market conditions. This rapid technology change potentially impacts the carrying value of our inventory on
hand due to obsolescence.

Disruption in supplies of certain essential components will impair our ability to manage our inventory with distributors and
resellers.

As a result of the acquisitions of Vertical Networks and Comdial, we now design and distribute the hardware on which many
of our software products operate. If our contract manufacturers are unable to obtain supplies necessary to the manufacture of our hardware, our ability to maintain inventory with our distributors and resellers will be harmed. Continued sales of our
hardware-based products are dependent upon continued availability of the commercially available components used to manufacture the custom hardware, as well as continued cooperation by the manufacturers involved in assembling the custom servers used
by the product. Our contract manufacturers may not be able to secure enough components at reasonable prices or of acceptable quality to build new products in a timely manner in the quantities or configurations needed. Accordingly, our revenues and
gross margins could suffer until other sources can be developed. Our operating results would also be adversely affected if, anticipating greater demand than actually develops, we commit to the purchase of more finished goods than we need. We cannot
assure you that we will not encounter these problems in the future. Although in many cases our contract manufacturers use standard parts and components for our products, certain components are presently available only from a single source or limited
sources. Our contract manufacturers may not be able to diversify sources in a timely manner, which could harm our ability to deliver products to customers and seriously impact present and future sales.

We do not manufacture the hardware utilized by InstantOffice and hold in-house only limited amounts of inventory for purposes of replacements of systems
or parts as required for field support. Should we experience a disruption in the supply of these finished goods, it could have a material adverse effect on our ability to sell and service our InstantOffice product line. The fact that we do not own
our manufacturing facilities could have an adverse impact on the supply of our products and on operating results. Financial problems of contract manufacturers on whom we rely, or reservation of manufacturing capacity by other companies, inside or
outside of our industry, could either limit supply or increase costs.

##### Table of Contents

As part of its restructuring program, Comdial outsourced substantially all of its manufacturing
requirements. Outsourced manufacturing is carried out in three principal locations: Asia, Mexico and the United States. Outsourcing, particularly with international manufacturers, carries certain risks which include, but may not be limited to:



| |  | the outsourcing contractors ability to manufacture products that meet our technical specification and that have minimal defects;
|- |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  | the outsourcing contractors ability to honor their product warranties;
|- |  | -----------------------------------------------------------------------



| |  | the financial solvency, labor concerns and general business condition of our outsourcing contractors;
|- |  | -----------------------------------------------------------------------------------------------------



| |  | unexpected changes in regulatory requirements;
|- |  | ----------------------------------------------



| |  | inadequate protection of intellectual property in foreign countries;
|- |  | --------------------------------------------------------------------



| |  | political and economic conditions in overseas locations;
|- |  | --------------------------------------------------------



| |  | risks of fire, flood or acts of God affecting manufacturing facilities; and
|- |  | ---------------------------------------------------------------------------



| |  | our ability to meet our financial obligations with our outsourcing contractors.
|- |  | -------------------------------------------------------------------------------

In addition, our new outsourcing contractors acquire component parts from various suppliers. Similar risks are involved in such procurement efforts. Due
to our new dependency on outsourced manufacturing and the inherent difficulty in replacing outsourced manufacturing capacity in an efficient or expeditious manner, the occurrence of any condition preventing or hindering the manufacture or delivery
of manufactured goods by any one or more of our outsourcing contractors would have a material adverse affect on our business in the short term and may have a material adverse affect in the long term. In calendar 2002, Comdial experienced significant
problems associated with a principal outsource manufacturer. Faulty component parts used by the manufacturer in the production of a principal product caused a significant shortfall in product inventory, and led to Comdials inability to meet
product orders, negatively impacting sales and revenues. In addition, Comdial was adversely affected by a port strike that resulted in the temporary closure of certain ports on the West Coast of the United States.

During the third quarter of 2002, Comdial experienced difficulties in fulfilling certain product orders as a result of the production transition from
Virginia to the outsourcing partners, and a backlog that has been built up with one of the United States outsourcing partners. Also in 2002, Comdial was forced to terminate its relationship with a principal outsource manufacturer and transition that
work to other contractors. The terminated manufacturer was unable to meet substantially all of Comdials product delivery orders because of financial and operational problems. That inability caused further problems for Comdial in meeting
customer orders and resulted in a substantial backlog, potential lost business and other losses. Comdial filed an arbitration action against that manufacturer in 2002 in order to seek recovery of the losses caused by their failure in performance.
While these problems with these contract manufacturers have been addressed by Comdial, we cannot give assurances that they will not continue to have an impact on sales and revenues, or that similar or other significant problems will not occur in the
future.

We rely upon LG-Nortel Co., Ltd. (LGN) as a strategic partner for our Vodavi business

Vodavi obtains a majority of our telephone systems, voice mail products and IP-based commercial grade telephones from LGN, which owns the rights to
produce this equipment. Under an agreement with Vodavi, LGN granted us the exclusive right to distribute and sell throughout North America and the Caribbean the products that LGN manufactures for us. The agreement expires in December 2009.
Vodavi conducts joint development activities with LGN for the design and development of hardware incorporated into some of their existing and planned telephone systems and commercial grade telephone product lines. Other products are completely
developed by LGN. In connection with the products jointly developed with LGN, Vodavi provides market analysis, product management, functional and performance standards, software development, quality control program development, sales and
distribution, and customer service and support, while LGN provides hardware research, design, and development, development of components such as integrated circuits and semiconductor chips, and manufacturing and production engineering. Generally,
LGN contributes the ongoing research and development costs for the product hardware in return for an arrangement under which LGN produces the finished goods developed under the alliance.

As a result of this arrangement, Vodavi has been able to obtain access to LGNs research and development expertise and resources while controlling
capital expenditures for much of their product development efforts. In addition, hte arrangement with LGN enables us to minimize the risks inherent in making significant investments in research and development infrastructure or personnel. To the
extent that we develop new hardware in conjunction with LGN or another development partner, the development partner typically retains ownership rights to the new hardware and we retain the right to sell products incorporating that hardware
throughout North America and the Caribbean. Vodavi relies on LGN to supply most of our telephone systems and voice mail products and all of their commercial grade telephones. They also rely on LGNs engineering, hardware and circuit
development, and manufacturing capabilities. Vodavi purchased approximately $21.2 million, $22.2 million, and $21.1 million of product LGN and LGITCH, constituting approximately 84%, 88%, and 87% of their total purchases in calendar years
2005, 2004, and 2003, respectively.

Additionally, we consider Nortel Networks Corporation, the controlling joint venture partner in LGN,
to be a direct competitor with our company in North America. Although, we have a long-term manufacturing and supply agreement with LGN that expires in December 2009, we cannot be assured that LGN will continue to support our business or
operations.

Certain conflicts of interest may arise as a result of LGNs ownership interest in our company.

LGN currently owns approximately 24% of our Series E Preferred Stock. We obtain most of our telephone systems, IP-based products, and voice mail
products for the Vodavi business from LGN and obtain all of their commercial grade telephones and replacement parts for such telephones from LGICTH, an affiliate of LGN. As a result of LGNs ownership interest in us, an inherent conflict of
interest exists in establishing the volume and terms and conditions of our purchases from LGN and LGICTH. In order to mitigate such conflicts, all decisions with respect to such purchases are made by our officers and may be reviewed by directors who
have no relationship with LGN.

Our relationship with LGN may have the effect of making more difficult or delaying attempts by others to
obtain control of us, even when these attempts may be in the best interests of stockholders. Through LGNs stockholder interest and business interests in our company, LGN may have significant influence over our business.

Undetected flaws in our products may damage our reputation, cause loss of customers and increase customer support costs.

Telecommunications products as complex as our products may contain undetected errors or flaws. The presence of any such errors or flaws could result in
damage to our reputation, loss of customers, delay of market acceptance of our products or all of these consequences. Our customers or we may find errors in current or any new products after commencement of commercial shipments. In addition, if our
products are flawed or are difficult to use, customer support costs could rise. If we are unable to timely and effectively correct flaws in our products, we will lose customers and our ability to make future sales will be adversely affected. If we
are unable to produce reliable products, our reputation will suffer, perhaps irreparably, and our business could fail.

Malfunctions or errors in
third-party technology may limit our ability to sell our products and may damage the reputation of our products, perhaps materially.

Our TeleVantage, Instant Office, Comdial and Vodavi products operate on or are comprised of hardware manufactured by third parties. We are dependent on the reliability of this hardware and, to the extent the hardware has defects, it will
affect the performance of our products. If the hardware becomes unreliable, does not perform in a manner that is acceptable to our customers or becomes more expensive, sales of our products could decline. Because many of our products run on
Microsoft software products and use other Microsoft Corporation technologies, we must depend on the reliability and quality of such products and technologies. Errors or vulnerabilities in Microsoft products could impair sales of some of our
products. Our customers may associate unreliability of the hardware and flaws in Microsoft products with a lack of quality of some of our products, which may cause us to lose customers and hurt future sales. Our ability to remedy malfunctions or
errors will depend on the timeliness and availability of repair solutions from the manufacturers. Future success of our products and any new products will depend on the ability of our hardware and software manufacturers to produce reliable products
in the future.

Many of our products incorporate technology licensed or acquired from third parties.

We sell products in markets that are characterized by rapid technological changes, evolving industry standards, frequent new product introductions, short
product life cycles and increasing levels of integration. Our ability to keep pace with this market depends on our ability to obtain technology from third parties on commercially reasonable terms to allow our products to remain in a competitive
posture. If licenses to such technology are not available on commercially reasonable terms and conditions, and we cannot otherwise integrate such technology, our products or our customers products could become unmarketable or obsolete, and we
could lose market share. In such instances, we could also incur substantial unanticipated costs or scheduling delays to develop substitute technology to deliver competitive products.

We are subject to risks associated with international operations.

We conduct business globally.
International sales accounted for approximately 3% of net sales for the quarter ended December 31, 2006 and 2% of net sales for the year ended June 30, 2006. We also acquire various raw materials and components from international
suppliers. We intend to expand our presence in international markets, and we cannot assure you that we will compete successfully in international markets or meet the service and support needs of foreign customers. Our future results could be harmed
by a variety of factors relating to international operations, including:



| |  |  | difficulties in enforcing agreements and collecting receivables through the legal systems of foreign countries;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | the longer payment cycles associated with many foreign customers;
| | - |  | -----------------------------------------------------------------



| |  |  | the possibility that foreign countries may impose additional withholding taxes or otherwise tax our foreign income, impose tariffs or adopt other restrictions on
foreign trade;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | fluctuations in exchange rates, which may affect product demand and adversely affect the profitability in U.S. dollars of products and services provided by us in
foreign markets where payment is made in local currency;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to obtain U.S. export licenses and other required export or import licenses or approvals;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | changes in the political, regulatory or economic conditions in a country or region; and
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | difficulty protecting our intellectual property in foreign countries.
| | - |  | ---------------------------------------------------------------------

Our market is highly competitive, and if we fail to compete successfully our products will not be successful.

We compete with other companies offering proprietary private branch exchanges, such as Nortel Networks Corporation, Siemens AG, and
Avaya, Inc. As we focus on the development and marketing of computer telephony systems, we face intense competition from providers of voice communications systems as well as from data networking companies such as Cisco Systems, Inc. and 3Com Corp.
In addition, because the market for our products is subject to rapid technological change, as the market evolves we may face competition in the future from companies that do not currently compete in the software- and server-based phone systems
market, including companies that currently compete in other sectors of the technology, communications and software industries. Competition from these potential market entrants may take many forms, including offering products and applications similar
to those we offer as part of a larger, bundled offering.

Comdial competed with approximately 25 companies, many of which have
significantly greater financial, marketing, and technical resources than we do. In addition, we must compete to attract and retain dealers for our new Comdial Products. There can be no assurance that we will be able to compete successfully in the
marketplace or that we will be able to maintain Comdials prior dealer network.

Several of these existing competitors have, and many
of our future competitors may have, greater financial, personnel and capacity resources than us and as a result, these competitors may be in a stronger position to respond quickly to potential acquisitions and other market opportunities, new or
emerging technologies and changes in customer requirements. Competitors with greater financial resources also may be able to offer lower prices, additional products or services or other incentives that we cannot match or do not offer. We cannot
predict with precision which competitors may enter our markets in the future or what form such competition may take. In order to effectively compete with any new market entrant, we may need to make additional investments in our business or use more
capital resources than our business currently requires.

We are relying on our next generation product to launch in mid-2007 and if we fail to achieve
general release in that time period our operations will be negatively impacted.

We are currently making a substantial investment in
the unified engineering and product management team that is working on our next-generation IP-PBX product family, which is expected to ship in 2007. If there are delays in release or insurmountable problems with this next generation product, our
operations will be negatively impacted as we require this new product to remain competitive in our market.

The failure of our products to perform
properly could result in a number of significant negative consequences to us, including a claim for substantial damages, the diversion of managements attention and resources, and damage to our reputation. In addition, current and prospective
customers may become discouraged from purchasing our products.

Because customers purchasing our products rely on them for the
communication needs of their respective businesses, we may be exposed to potential claims for damages, including special or consequential damages, as a result of an actual or perceived failure of our products. Our failure or inability to meet a
customers expectations in the performance of our products, or failure to address any failure of our products in a timely manner, regardless of our responsibility for failure, could (1) result in a claim for substantial damages against us;
(2) divert managements attention and resources; (3) damage our business reputation; and (4) discourage other customers from purchasing our products in the future.

We maintain certain contractual limitations of liability and insurance against some of these risks; however, there can be no assurance that such
provisions would be enforced or effective or that such insurance would be sufficient to cover the cost of damages. Further, we cannot assure you that insurance will continue to be available at commercially reasonable rates. If we are unable to rely
on our contractual limitations of liability and/or maintain sufficient insurance, our business could be harmed.

Our market is subject to changing
preferences and technological change, and our failure to keep up with these changes would harm our business and prospects, perhaps materially.

The introduction of products incorporating new technologies and the emergence of new industry standards could render our products obsolete and unmarketable. If we are unable to stay current or ahead of changes in the technology or industry
standards, our business and prospects will suffer, perhaps materially. We cannot assure you that we will be able to respond to rapid technological change, changing customer needs, frequent product introductions and evolving industry standards within
the markets for computer telephony solutions. We may be unable to develop and introduce new computer telephony products (including new releases and enhancements) on a timely basis that keep pace with technological developments and emerging industry
standards and address the increasingly sophisticated needs of our customers.

We have adopted anti-takeover defenses that could make it difficult for
another company to acquire control of our company or limit the price investors might be willing to pay for our stock.

Certain provisions of our Certificate of Incorporation, as amended, could make a merger, tender offer or
proxy contest involving us difficult, even if such events would be beneficial to the interests of our stockholders. These provisions include a classified board of directors, restrictions on calling and holding stockholder meetings, and giving our
board the ability to issue preferred stock and determine the rights and designations of the preferred stock at any time without stockholder approval. The rights of the holders of our common stock will be subject to, and may be adversely affected by,
the rights of the holders of any preferred stock that may be issued in the future. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it
more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of our outstanding voting stock. These factors and certain provisions of the Delaware General Corporation Law may have the effect of deterring
hostile takeovers or otherwise delaying or preventing changes in control or changes in our management, including transactions in which our stockholders might otherwise receive a premium over the fair market value of our common stock.

Our protection of intellectual property may not allow us to effectively prevent others from using our business model or our technology.

Our success is dependent upon our software code base, our programming methodologies and other intellectual property. We rely on copyright protection for
such works of authorship and trade secret protection for our technical know-how and other confidential information. We do not currently maintain patent protection for our business model or our technology and we currently do not plan significant
patent applications in the future. We generally enter into confidentiality agreements with our employees, vendors and consultants and with our clients and corporations with whom we have strategic relationships; however, the terms of these agreements
vary and may not provide us with adequate protection against non-disclosure. In addition, we attempt to maintain control over, access to, and distribution of our intellectual property and technical know-how; however, despite these efforts,
unauthorized parties may attempt to copy aspects of our service offering or the documentation used by us in delivering such services or to obtain and use other information that we regard as proprietary.

Monitoring infringement of intellectual property rights is difficult and we cannot be certain that the steps we have taken will prevent unauthorized use
of our intellectual property and technical know-how, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. Accordingly, other parties, including competitors, may duplicate our
product offerings.

Furthermore, Comdial has, from time to time, been subject to proceedings alleging infringement of the intellectual
property rights of others. We may find ourselves defending infringement claims related to intellectual property assets that are included in the Comdial Assets. Such proceedings could require us to expend significant sums in litigation, pay
significant damages, develop non-infringing technology, or acquire licenses to the technology which is the subject of the asserted infringement, any of which could have a material adverse effect on our business. Moreover, Comdial has relied in the
past upon intellectual property rights to protect its proprietary rights in its products and software. There can be no assurance that these protections will be adequate to deter misappropriation of our new Comdial technologies or independent
third-party development of potentially infringing technologies.

We may become involved in intellectual property or other disputes that could cause us
to incur substantial costs, divert the efforts of our management, and require us to pay substantial damages or require us to obtain licenses, which may not be available on commercially reasonable terms, if at all.

Third parties, including competitors, may already have patents on inventions, or may obtain patents on new inventions in the future, that could limit our
ability to market and sell the products we provide now or new products we may offer in the future. Such third parties may claim that our products infringe their patent rights and assert claims against us. In addition, we have agreed in some of our
contracts, and may in the future agree in other contracts, to indemnify third parties for any expenses or liabilities resulting from claimed infringements of the proprietary rights of third parties as it relates to the products we provide. We, or
third parties that we are obligated to indemnify, may receive notifications alleging infringements of intellectual property rights relating to our business or the products previously sold by us. Litigation with respect to patents or other
intellectual property matters, whether with or without merit, could be time-consuming to defend, result in substantial costs and diversion of management and other resources, cause delays or other problems in the marketing and sales of our products,
or require us to enter into royalty or licensing agreements, any or all of which could have a material adverse effect on our business, operating results and financial condition. If any infringement claim is successful against us, we may be required
to pay substantial damages or we may need to seek and obtain a license of the other partys intellectual property rights. We may be unable to obtain such a license on commercially reasonable terms, if at all. We may be required to redesign
those products that use the infringed technology. Moreover, we may be prohibited from selling, using, or providing any of our products that use the challenged intellectual property. Although we carry general liability insurance, our insurance may
not cover potential claims of this type or may not be adequate to cover us for all liability that may be imposed.

Our common stock has a limited
trading market, which could limit the liquidity of our common stock and our access to capital markets.



39



---

##### Table of Contents

Our common stock is currently quoted on both the over-the-counter electronic bulletin board, also
referred to as the OTC Bulletin Board, and the National Quotation Service Bureau, also known as the Pink Sheets. There is only limited trading activity in our securities. We do not know if a market for our common stock will be re-established or
that, if re-established, a market will be sustained. This could limit the liquidity of our common stock and reduce our stock price. The limited liquidity and reduced price of our common stock could have a material adverse effect on our ability to
raise capital through alternative financing sources on terms acceptable to us or at all. The limited trading market may also result in other negative implications, including the potential loss of confidence by suppliers, customers and employees, the
loss of institutional investor interest and fewer business development opportunities.

Our common stock is subject to additional regulation as a
penny stock, which may reduce the liquidity of our common stock.

The SEC has adopted regulations that generally define a
penny stock to be any security that is priced under five dollars. These regulations may have the effect of reducing the level of trading activity in our common stock and investors in our common stock may find it difficult to sell their
shares. We cannot assure you that you will be able to resell our common stock and may lose your investment.

In addition, since the trading
price of our common stock is less than $5.00 per share, trading in our common stock is also subject to the requirements of Rule 15g-9 of the Exchange Act. Under Rule 15g-9, brokers who recommend our common stock to persons who are not established
customers and accredited investors, as defined in the Exchange Act, must satisfy special sales practice requirements, including requirements that they:



| |  |  | make an individualized written suitability determination for the purchaser; and
| | - |  | -------------------------------------------------------------------------------



| |  |  | receive the purchasers written consent prior to the transaction.
| | - |  | -----------------------------------------------------------------

The Securities Enforcement Remedies and Penny Stock Reform Act of 1990 also requires additional disclosures in connection with any trades involving a
penny stock, including the delivery, prior to any penny stock transaction, of a disclosure schedule explaining the penny stock market and the risks associated with that market. Such requirements may severely limit the market liquidity of our common
stock and the ability of purchasers of our equity securities to sell their securities in the secondary market. For all of these reasons, an investment in our equity securities may not be attractive to our potential investors.

Revenues in any quarter may vary to the extent recognition of revenue is deferred when contracts are signed. As a result, revenues in any quarter may be difficult to
predict and are unreliable indicators of future performance trends.

We frequently enter into contracts where we recognize only a
portion of the total revenue under the contract in the quarter in which we enter into the contract. For example, we may recognize revenue on a ratable basis over the life of the contract or enter into contracts where the recognition of revenue is
conditioned upon delivery of future product or service elements. This is the case with our contracts with CVS, Aramark and Household Financial. The portion of revenues that are deferred may vary significantly in any given quarter, and revenues in
any given quarter are a function both of contracts signed in such quarter and contracts signed in prior quarters. We anticipate that product revenues in future quarters will generally be more dependent on revenues from new customer contracts entered
into in those quarters rather than from amortization or recognition of product revenues deferred in prior quarters.

We sometimes experience long
implementation cycles, which may increase our operating costs and delay recognition of revenues.

Our products are sophisticated
systems that are generally deployed with many users. Implementation of these systems by enterprises is complex, time consuming and expensive. Long implementation cycles may delay the recognition of revenue as some of our customers engage us to
perform system implementation services, which can defer revenue recognition for the related product revenue. In addition, when we experience long implementation cycles, we may incur costs at a higher level than anticipated, which may reduce the
anticipated profitability of a given implementation.

Our costs could substantially increase if we receive a significant number of warranty claims.

We generally warrant each of our products against defects in materials and workmanship for a period of 12 months from the date of
shipment. If we experience an increase in product returns or warranty claims, we could incur unanticipated additional expenditures for parts and service. In addition, our reputation and goodwill could be damaged, perhaps irreparably. While we have
established reserves for liability associated with product warranties, unforeseen warranty exposure in excess of those reserves could adversely affect our operating results.
