                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        SIX MONTHS ENDED AUGUST 31, 1998


NOTE A -- BASIS OF PRESENTATION

The accompanying financial statements have been prepared in accordance with
generally accepted accounting principles for interim financial information. The
consolidated balance sheet at February 28, 1998 has been derived from audited
financial statements at that date. In the opinion of management, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation of the unaudited August 31, 1998 and 1997 consolidated financial
statements have been included. Operating results for the six month period ended
August 31, 1998 are not necessarily indicative of the results that may be
expected for the year ending February 28, 1999 as they may be affected by a
number of factors, including the timing and ultimate receipt of orders from
significant customers which continue to constitute a large portion of the
Company's sales, the sales channel mix of products sold, and changes in general
economic conditions, any of which could have an adverse effect on operations.

NOTE B - REVENUE RECOGNITION

The Company recognizes revenue for sales of systems which do not require
customization by the Company at the time of shipment. Subsequent to December 1,
1997, revenue for systems which require customization by the Company are
recognized by the contract method of accounting using percentage of completion
for larger, more complex systems (generally over a $500,000 sales price) and the
completed contract method for smaller systems. Prior to December 1, 1997, the
Company recognized revenue on systems requiring customization at the date of
shipment or at the point after shipment when the remaining obligations of the
Company became insignificant. This change in accounting was required by the
American Institute of CPA's Statement of Position 97-2 which was adopted by the
Company as of December 1, 1997 and is required to be applied prospectively for
transactions entered into after that date.

The Company recognizes revenue from services at the time the service is
performed or over the period of the contract for maintenance/support.

NOTE C - EARNINGS PER SHARE

Basic earnings per share exclude any dilutive effect of stock options and
restricted stock arrangements. Diluted earnings per share includes the dilutive
impact of stock options and restricted stock arrangements.

The following table sets forth the computation of basic and diluted earnings per

Options to purchase 286,850 and 1,899,257 shares of common stock at average
prices of $21.20 and $13.40, respectively, were outstanding during the three
months ended August 31, 1998 and 1997, respectively, but were not included in
the computation of diluted earnings per share because the options' prices were
greater than the average market price of the Company's common shares during such
periods and, therefore, the effect would have been anti-dilutive. For the same
reasons, 299,850 and 937,512 shares of common stock at average prices of $20.96
and $16.89, respectively, were outstanding and not included in the computation
of diluted earnings per share during the six months ended August 31, 1998 and
1997, respectively.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

         SALES. Sales in the first six months and second quarter of fiscal 1999
increased approximately $9.1 million and $3.8 million, respectively, or 17% and
13%, respectively, when compared to the same periods of fiscal 1998. These
increases were due primarily to increased domestic customer premise equipment
(CPE) sales. A portion of the increase is attributable to customer demand for
the Company's recently released host computer and operating system independent
products. The Company also has been successful in focusing its efforts on
diversifying into vertical markets in which the Company has not previously
participated, such as inbound call centers. This diversification also has
influenced the Company's increased domestic CPE sales. For the first six months
and second quarter of fiscal 1999, such sales constituted 61% and 69% of the
Company's total sales, respectively, and increased 20% and 37%, respectively,
when compared to the same periods of fiscal 1998.

Worldwide telecommunications (Telco) sales for the first six months and second
quarter of fiscal 1999 constituted 19% and 13%, respectively, of the Company's
total sales. Such sales for the first six months of fiscal 1999 increased 34%
when compared to the same period of fiscal 1998. Worldwide Telco sales decreased
30% in the second quarter of fiscal 1999, as compared to the same period of
fiscal 1998 in which the Company recorded two large sales to Latin American
telecommunications companies. Sales to domestic Telco customers constituted 51%
and 84% of the Company's worldwide telecommunications sales during the first six
months and second quarter of fiscal 1999, respectively. A sale to a domestic
long distance company constituted approximately 65% of domestic Telco sales
during the second quarter of fiscal 1999. While international Telco sales during
the second quarter of fiscal 1999 were weak, the Company believes international
demand, particularly in Latin America, remains strong.

International CPE sales and service revenue constituted the remaining 20% and
18% of the Company's total sales during the first six months and second quarter
of fiscal 1999, respectively. No customer accounted for 10% or more of the
Company's total sales during the first six months or second quarter of fiscal
1999.

         COST OF GOODS SOLD. Cost of goods sold of approximately $26.0 million
during the first six months decreased to 41% of total sales from 42% in the same
period of the previous year. This was the result of increased sales and the
Company's continued emphasis on expense control. Cost of goods sold of
approximately $13.4 million during the second quarter of fiscal 1999 increased
to 41% of total sales from 39% in the same period of the previous year. This was
the result of a decrease of international sales in the mix of the Company's
total sales. International sales historically have a lower cost of sales
percentage than domestic sales due to a more favorable software to hardware
ratio.

         RESEARCH AND DEVELOPMENT. Research and development expenses were
approximately $6.5 million and $3.2 million during the first six months and
second quarter of fiscal 1999, respectively. Research and Development expenses
during the first six months of


<PAGE>   9



fiscal 1999 were approximately equal to such expenses in the same period of the
previous year and declined approximately $0.3 million, or 8%, in the second
quarter of fiscal 1999 versus the same period in fiscal 1998. Such a decline was
in line with the Company's emphasis on expense control. Research and development
expenses during the first six months and second quarter of fiscal 1999 included
porting the Company's InterSoft core software to the UNIX and Windows NT
operating systems; developing computer platform independent voice automation
hardware and software; developing the NSP 5000 platform; and the integrating of
the ESP product line purchased from Integrated Telephony Products, Inc. into the
Company's InControl product offering for enhanced network services.
Additionally, expenditures were made for the ongoing development of the
Company's OneVoice Software Agent Platform including OneVoice Systems (the
Company's IVR system), InVision (the Company's custom application development
tool), InterDial (the Company's outbound predictive dialer system), OneLink (a
digital interface for analog switches), and digital VocalCard software and
hardware functionality.

         SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and
administrative expenses decreased to approximately $19.0 million and $9.5
million during the first six months and second quarter of fiscal 1999,
respectively, from approximately $21.4 million and $11.3 million during the same
periods of the previous year. As a percentage of the Company's total sales, such
expenses decreased to 30% in the first six months of fiscal 1999 from 40% in the
same period of fiscal 1998, and to 29% in the second quarter of fiscal 1999 from
39% in the same period of fiscal 1998. The Company has continued its measures to
control expenses, particularly selling, general and administrative expenses.

         OTHER INCOME/EXPENSE. Other expense of approximately $0.2 million and
$0.1 million during the first six months and second quarter of fiscal 1999,
respectively, was primarily net interest expense paid on its short term
borrowings.

         INCOME FROM OPERATIONS. Operating income and net income during the
first six months of fiscal 1999 were approximately $11.6 million and $7.4
million, respectively, compared to $3.2 million and $2.5 million, respectively,
during the same period of the previous year. Operating income and net income
during the second quarter of fiscal 1999 were approximately $6.9 million and
$4.4 million, respectively, compared to approximately $3.0 million and $2.2
million, respectively, during the same period of the previous year. The
increases in operating income and net income are the result of increased sales
and the Company's efforts to control expenses.

         LIQUIDITY AND CAPITAL RESOURCES. At August 31, 1998, the Company had
cash reserves of approximately $8.2 million while borrowings under the Company's
unsecured, revolving credit line with NationsBank were $9.0 million. Operating
cash flow during the first six months and second quarter of fiscal 1999 were
approximately a positive $9.8 million and $6.6 million, respectively. Investing
activities, primarily the purchase of computer and test equipment, during the
first six months and second quarter of fiscal 1999 consumed $2.7 million and
$1.3 million, respectively. The re-purchase of the Company's common stock during
the first six months and second quarter of fiscal 1999 consumed $4.4 million and
$4.3 million, respectively. Proceeds from the exercise of employee stock options
during the first six months and second quarter of fiscal 1999 contributed $1.3
million and $0.9 million, respectively. Net 


<PAGE>   10

cash flow during the first six months and second quarter of fiscal 1999 was $4.1
million and $1.9 million, respectively. The Company did not increase its
borrowings during the quarter.

The Company reviews share repurchase and acquisition opportunities from time to
time. During the first six months and second quarter of fiscal 1999, the Company
repurchased 234,000 and 224.000 shares, respectively, of its common stock at
costs of $4,385,638 and $4,267,738 respectively, pursuant to an authorization by
its Board of Directors. The Company believes that market conditions made the
repurchase of such shares of value to its shareholders and that it has access to
the financial resources necessary to pursue attractive repurchase and/or
acquisition opportunities as they arise.

Subsequent to August 31, 1998, the Company purchased a computer telephony
software suite from Dronen Consulting, Incorporated for $3.0 million in cash
and 75,000 shares of the Company's common stock. The cash portion of the
purchase price was sourced from cash reserves. The Company's borrowings were not
increased as a result of the purchase.

The Company believes its cash reserves and internally generated cash flow are
sufficient to meet its operating cash requirements for the foreseeable future.
Additionally, the Company is in process of renegotiating its unsecured,
revolving credit line with NationsBank and expects to complete such
renegotiation by the end of October, 1998.

         FORWARD LOOKING STATEMENTS. This report on Form 10-Q includes
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended. All statements other than statements of historical facts included in
this announcement regarding the Company's financial position, business strategy,
plans and objectives of management of the Company for future operations, and
industry conditions, are forward-looking statements. Although the Company
believes that the expectations reflected in such forward-looking statements are
reasonable, it can give no assurance that such expectations will prove to be
correct. The following significant factors, among others, sometimes have
affected, and in the future could affect, the Company's actual results and could
cause such results during fiscal 1999, and beyond, to differ materially from
those expressed in any forward-looking statements made by or on behalf of the
Company:

o    The Company faces intense competition based on product capabilities and
     experiences ever-increasing demands from its actual and prospective
     customers for its products to be compatible with a variety of rapidly
     proliferating computing, telephony and computer networking technologies and
     standards. The ultimate success of the Company's products is dependent, to
     a large degree, on the Company allocating its resources to developing and
     improving products compatible with those technologies, standards and
     functionality's that ultimately become widely accepted by the Company's
     actual and prospective customers. The Company's success is also dependent,
     to a large degree, on the Company's ability to implement arrangements with
     other vendors with complementary product offerings to provide actual and
     prospective customers greater functionality and to ensure that the
     Company's products are compatible with the increased variety of
     technologies and standards.



<PAGE>   11

o    Continued availability of suitable non-proprietary computing platforms and
     system operating software that are compatible with the Company's products.

o    Certain of the components for the Company's products are available from
     limited suppliers. The Company's operating results could be adversely
     affected if the Company were unable to obtain such components in the
     future.

o    Increasing litigation with respect to the enforcement of patents,
     copyrights and other intellectual property.

o    The ability of the Company to retain its customer base and, in particular,
     its more significant customers such as Siemens AG, an InterVoice
     distributor, which accounted for over ten percent of the Company's total
     sales during fiscal 1998. Since such customers generally are not
     contractually obligated to place further orders with the Company.

o    Legislative and administrative changes and, in particular, changes
     affecting the telecommunications industry, such as the Telecommunications
     Act of 1996. While many industry analysts expect the Telecommunications Act
     of 1996 ultimately to result in at least a temporary surge in the
     procurement of telecommunications equipment and related software and other
     products, there is no assurance that the Company can estimate with
     sufficient accuracy those products which will ultimately be purchased, the
     timing of any such purchases or the quantities to be purchased.

o    Risks involved in the Company's international distribution and sales of
     its products, including unexpected changes in regulatory requirements,
     unexpected changes in exchange rates, the difficulty and expense of
     maintaining foreign offices and distribution channels, tariffs and other
     barriers to trade, difficulty in protecting intellectual property rights,
     and foreign governmental regulations that may limit or restrict the sales
     of call automation systems. Additionally, changes in foreign credit markets
     and currency exchange rates may result in requests by many international
     customers for extended payment terms and may have an adverse impact on the
     Company's cash flow and its level of accounts receivable.

o    The quantity and size of large sales (sales valued at approximately $1
     million or more) during any fiscal quarter, which can cause wide variations
     in the Company's sales and earnings on a quarter to quarter basis.

o    Ability of the Company to properly estimate costs under fixed price
     contracts in developing application software and otherwise tailoring its
     systems to customer-specific requests.

o    The Company's ability to hire and retain, within the Company's
     compensation parameters, qualified technical talent and outside contractors
     in highly competitive markets for the services of such personnel.

o    Mergers and acquisitions between companies in the telecommunications
     industry which could result in fewer companies purchasing the Company's
     products for telecommunications applications, and/or delay such purchases
     by companies that are in the process of reviewing their strategic
     alternatives in light of a merger or acquisition.

<PAGE>   12
