                     NOTES TO UNAUDITED FINANCIAL STATEMENTS

                       NINE MONTHS ENDED NOVEMBER 30, 1997

NOTE A -- BASIS OF PRESENTATION

The accompanying financial statements have been prepared in accordance with
generally accepted accounting principles for interim financial information. The
Balance Sheet at February 28, 1997 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 November 30, 1997 and 1996 financial statements
have been included. Operating results for the nine month period ended November
30, 1997 are not necessarily indicative of the results that may be expected for
the year ending February 28, 1998 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 -- EARNINGS PER SHARE

Earnings per share are computed based on the sum of the average outstanding
common shares and common equivalent shares. Common equivalent shares assume the
exercise of all dilutive stock options using the treasury stock method. Primary
and fully diluted earnings per share are not materially different for the
periods presented.

On February 28, 1998, the Company will be required to adopt Statement No. 128
"Earnings per Share" issued by the Financial Accounting Standards Board. Under
the new method of computing 



<PAGE>   7

earnings per share, the dilutive effect of stock options will be excluded. At
the time of adoption, the Company will compute earnings per share under the new
method and will restate all prior periods.

NOTE C -- CONTINGENCIES

The Company is subject to certain legal proceedings and claims that arise in the
ordinary course of its business. In the opinion of management, based on
discussions with and advice of legal counsel, the amount of ultimate liability
with respect to these actions will not materially affect the consolidated
results of operations or financial condition of the Company.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL

                       CONDITION AND RESULTS OF OPERATIONS

     SALES. Sales in the first nine months and third quarter of fiscal 1998
increased approximately $2.4 million and $1.2 million, respectively, or 3% and
5%, respectively, when compared to the same periods of fiscal 1997. These
increases were due primarily to increased domestic customer premise equipment
(CPE) sales and international telecommunications (Telco) sales, particularly to
Latin American telecommunications companies. Domestic CPE sales for the first
nine months and third quarter of fiscal 1998 constituted 58% and
56%,respectively, of the Company's total sales and increased 14% and 16%,
respectively, when compared to the same periods of fiscal 1997.

     Worldwide Telco sales for the third quarter of fiscal 1998 constituted 18%
of the Company's total sales and increased 45% when compared to the same period
of fiscal 1997. Even though worldwide Telco sales improved during the third
quarter, such sales in the first nine months of fiscal 1998 were approximately
equal to Telco sales in the same period of fiscal 1997, due to lower domestic
Telco sales in the first half of fiscal 1998. As a result, worldwide Telco sales
constituted 17% of the Company's total sales for the first nine months of both
fiscal 1998 and fiscal 1997. Sales to international Telco customers constituted
75% and 73% of the Company's worldwide telecommunications sales during the first
nine months and third quarter of fiscal 1998, respectively, compared to 19% and
54%, respectively, in the same periods of fiscal 1997. The Company believes that
beginning in the second half of fiscal 1997 some domestic telecommunications
companies began to temporarily delay their implementation of call automation
solutions while they further evaluate marketing investment strategies in the
light of new opportunities resulting from deregulation.



<PAGE>   9

     International CPE sales and service revenue constituted the remaining 25%
of the Company's total sales during the first nine months of fiscal 1998
compared to 30% in the same period of fiscal 1997. International sales and
service revenues were 26% of the Company's total sales during the third quarter
of fiscal 1998 as compared to 37% in the same period of fiscal 1997. The Company
enjoyed a large sale to a Latin American CPE customer in the third quarter of
fiscal 1997. No customer accounted for 10% of the Company's total sales during
the first nine months or third quarter of fiscal 1998.

     The Financial Accounting Standards Board has approved the American
Institute of Certified Public Accountants Statement of Position 97-2 (SOP ) on
software revenue recognition on sales requiring a high degree of software
customization, which currently account for approximately 30% of the Company's
total sales. The SOP must be adopted by the Company effective with the beginning
of its fiscal 1999. The Company, however, may consider early adoption of the
SOP, but has not yet determined when it will do so. While at this time the
Company cannot predict or quantify the impact of the new SOP, it may delay the
recognition of revenue on certain sales when adopted by the Company.

     COST OF GOODS SOLD. Cost of goods sold as a percentage of sales increased
to 44% and 46% in the first nine months and the third quarter of fiscal 1998,
respectively, compared to 38% and 40%, respectively, in the same periods of
fiscal 1997. This was the result of less than anticipated sales in the first
nine months and third quarter of fiscal 1998 and the Company's continued
investment in applications engineering and customer service resources to pursue
opportunities in both the CPE and Telco markets.

     RESEARCH AND DEVELOPMENT. Research and development expenses in the first
nine months and third quarter of fiscal 1998 increased approximately $1.1
million and approximately $0.3 million, or 13% and 9%, respectively, over the
same periods of fiscal 1997. Such expenses in 


<PAGE>   10

the first nine months and third quarter of fiscal 1998 increased to 12% and 13%,
respectively, of the Company's total sales, versus 11% and 12%, respectively, in
the same periods of fiscal 1997. Research and development expenses in the first
nine months and third quarter of fiscal 1998 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; and the
development of VisualConnect (the ability to communicate with OneVoice Systems
via the Internet) and InVision (the Company's next generation custom application
development tool).

     The Company continued development of its OneVoice Software Agent Platform
including OneVoice Systems (the Company's Interactive Voice Response (IVR)
system), OneVoice 5000 (the Company's high density IVR system), InterDial (the
Company's outbound predictive dialer system), OneLink (a digital interface for
analog switches), and digital VocalCard software and hardware functionality.
Expenditures also were made for the completion of the Company's "InControl"
product line including the NSP5000 platform, which addresses the worldwide Telco
market.

     SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative
expenses increased approximately $7.5 million and approximately $2.1 million in
the first nine months and third quarter of fiscal 1998, respectively, or 31% and
27%, respectively, as compared to fiscal 1997. As a percentage of the Company's
total sales, selling, general and administrative expenses in the first nine
months and third quarter of fiscal 1998 both increased to 40%. This was the
result of the Company's continued investments in hiring and training new and
existing sales, service and support personnel and in marketing and advertising
programs worldwide to pursue opportunities in both the CPE and Telco markets,
despite less than anticipated sales.

     OTHER INCOME. Other income during the first nine months and third quarter
of fiscal 1998 were comparable with the same periods of fiscal 1997.



<PAGE>   11

     INCOME FROM OPERATIONS. Operating income during the first nine months and
third quarter of fiscal 1998 of approximately $3.5 million and $0.3 million,
respectively, declined 75% and 83%, respectively, from the same periods in the
previous year. Despite less than anticipated sales, the Company increased its
investments in sales, marketing, application engineering and research and
development during the first half of fiscal 1998 in order to continue to pursue
opportunities in both the CPE and Telco markets. Net income during the first
nine months and third quarter of fiscal 1998 of approximately $2.5 million and
$2.2 million, respectively, declined 71% and 80%, respectively, from the same
periods in the previous year for the same reasons as operating income. The
Company has undertaken measures to control expenses, particularly selling,
general and administrative expenses. These expense control measures should begin
to reduce the Company's ratio of expenses to sales in future quarters, assuming
sales in future quarters remain at or above third quarter sales, and further
assuming that expense levels are not unduly influenced by unusually high one
time expenses related to litigation matters, any potential mergers or
acquisitions, any major research and development efforts which are not currently
contemplated but which become necessary in light of market or strategic
requirements, or any other future contingencies which are not currently
contemplated by the Company.

     LIQUIDITY AND CAPITAL RESOURCES. At November 30, 1997, the Company had cash
reserves of approximately $6.5 million. The Company generated positive net cash
from operations of approximately $10.1 million and $4.5 million during the first
nine months and third quarter of fiscal 1998, respectively. Investing activities
(consisting of the acquisition and purchase of fixed assets and third party
software) and financing activities (consisting primarily of the repurchase of
shares of the Company's common stock) together used approximately $27.8 million
and $18.3 million of cash during the first nine months and third quarter of
fiscal 1998, respectively. Investment activities totaling approximately $9.8
million and $1.8 million during the first nine months and third quarter of
fiscal 1998 included purchasing computing hardware and software to 


<PAGE>   12

update the Company's enterprise systems and to provide the information systems
infrastructure needed to support the Company's worldwide growth. Expenditures
were also made to acquire third party developed software to be integrated into
the Company's InterSoft software to allow the Company to offer its customers
greater functionality and to ensure the Company's products comply with an
increasing variety of hardware and software technologies and standards.
Financing activities during the nine months and third quarter of fiscal 1998
included the repurchase of 1,818,500 and 1,637,836 shares of the Company's
common stock, respectively, at a cost of approximately $18.2 million and $16.4
million, respectively, pursuant to authorization by its Board of Directors to
repurchase up to an aggregate of 2,000,000 shares. The Company believes that
market conditions made such shares of value to its shareholders. As a result of
these financing and investing activities, the Company experienced a reduction of
its cash reserves of approximately $17.7 million and $16.5 million during the
first nine months and third quarter of fiscal 1998, respectively. Subsequent to
the end of the third quarter of fiscal 1998 and as of December 31, 1997, the
Company repurchased an additional 181,500 shares of the Company's stock at a
cost of $1,358,960 to complete the share repurchase authorization mentioned
above. The Company reviews share repurchase and acquisition opportunities from
time to time and believes it has access to the financial resources necessary to
pursue attractive opportunities as they arise. On January 8, 1998, the Company's
Board of Directors authorized the repurchase of an additional 2,000,000 shares
of the Company's stock. As of January 14, 1998, the Company has not repurchased
shares of the Company's stock pursuant to the January 8, 1998 authorization.

     On December 16, 1997, the Company announced the purchase, subject to normal
closing conditions, of the Enhanced Service Platform (ESP) product line from
Integrated Telephony Products, Inc., (ITP). The purchase is expected to close
during January, 1998. As consideration for the purchase, the Company is paying
ITP $4.0 million in cash and will issue ITP unregistered shares of the Company's
common stock with a market value equivalent to $0.5 million. While, as of
January 14, 1998, a final determination has not been made, the Company expects
to write off 


<PAGE>   13

during the fourth quarter of fiscal 1998 a portion of the purchase price which
is attributable to in-process research and development

     On December 17, 1997, the Company announced the resignation of Michael W.
Barker as its President and Chief Operating Officer and as a Director of the
Company. The Company expects to record expenses of approximately $0.5 million
during the fourth quarter of fiscal 1998 associated with Mr. Barker's
resignation.

     On November 3, 1997, the Company completed an unsecured revolving credit
line agreement with NationsBank for $15 million. As of January 14, 1998, the
Company's credit line is available in its entirety. The Company believes that
its cash reserves, internally generated cash flow and credit line are sufficient
to meet its cash requirements for the foreseeable future.


     DISCLOSURES REGARDING FORWARD-LOOKING STATEMENTS. This Form 10-Q
announcement 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 Form 10-Q 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 1998, and
beyond, to differ materially from those expressed in any forward-looking
statements made by or on behalf of the Company:



<PAGE>   14

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
     functionalities 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.

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 1997 and MCI Telecommunications, which accounted for
     over ten percent of the Company's total sales during fiscal 1996 and 1995),
     since 

<PAGE>   15

     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 recently enacted
     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.



<PAGE>   16

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 Telco 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.

o    Extreme price and volume trading volatility in the U.S. stock market, which
     has had a substantial effect on the market prices of securities of many
     high technology companies, frequently for reasons other than the operating
     performance of such companies. These broad market fluctuations could
     adversely affect the market price of the Company's common stock.
