                                    PART III
                                    NARRATIVE

State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q,
10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be
filed within the prescribed time period. (Attach extra sheets if needed.)

     Comverse Technology, Inc. (the "Company") plans to file its Quarterly
     Report on Form 10-Q for the quarter ended April 30, 2006 as soon as
     practicable, but does not currently expect that it will be filed on or
     before the fifth calendar day following the required filing date as
     prescribed in Rule 12b-25.

     As previously announced on March 14, 2006, the Company's Board of Directors
     created a special committee (the "Special Committee") composed of outside
     directors to review matters relating to the Company's stock option grants,
     including the accuracy of the stated dates of option grants and whether all
     proper corporate procedures were followed. The Special Committee is being
     assisted by independent outside legal counsel and accounting experts. At
     this time, the Special Committee has not completed its work or reached
     final conclusions and is continuing its review. The Special Committee has,
     however, reached a preliminary conclusion that the actual dates of
     measurement for certain past stock option grants for accounting purposes
     differed from the recorded grant dates for such awards. As a result of
     changes in measurement dates, the Company expects to record additional
     non-cash charges for stock-based compensation expenses in prior periods.
     Based on the Special Committee's preliminary conclusion, the Company
     expects that (i) such non-cash charges will be material and (ii) the
     Company will need to restate its historical financial statements for each
     of the fiscal years ended January 31, 2005, 2004, 2003, 2002 and 2001 and
     for the first three quarters of the fiscal year ended January 31, 2006.


                                       2


     Such charges could also affect prior periods. On April 14, 2006, the Audit
     Committee of the Company's Board of Directors concluded that such financial
     statements and any related reports of its independent registered public
     accounting firm should no longer be relied upon.

     Any such stock-based compensation charges would have the effect of
     decreasing the income from operations, net income and retained earnings
     figures contained in the Company's historical financial statements. The
     Company does not expect that the anticipated restatements would have a
     material impact on its historical revenues, cash position or non-stock
     option related operating expenses.

     The Company intends to issue results for the quarterly period ended April
     30, 2006, and to file its Quarterly Report on Form 10-Q for the quarter
     ended April 30, 2006 together with any restated historical financial
     statements, as soon as practicable after the completion of the Special
     Committee's review.

     Note: This Form 12b-25 contains "forward-looking statements" under the
     Private Securities Litigation Reform Act of 1995 that involve risks and
     uncertainties. There can be no assurances that forward-looking statements
     will be achieved, and actual results could differ materially from forecasts
     and estimates. Important factors that could cause actual results to differ
     materially include: the results of the review of the Special Committee,
     appointed by the Board of Directors on March 14, 2006, of matters relating
     to the Company's stock option grants, including, but not limited to, the
     accuracy of the stated dates of option grants and whether all proper
     corporate procedures were followed; the impact of any restatement of
     financial statements of the Company or other actions that may be taken or
     required as a result of such reviews; the Company's inability to file
     reports with the Securities and Exchange Commission; risks associated with
     the Company's inability to meet NASDAQ requirements for continued listing,
     including possible delisting; risks of litigation and of governmental
     investigations or proceedings arising out of or related to the Company's
     stock option grants or any restatement of the financial statements of the
     Company; risks associated with integrating the businesses and employees of
     the GSS division of CSG Systems, International and Netcentrex S.A.; changes
     in the demand for the Company's products; changes in capital spending among
     the Company's current and prospective customers; the risks associated with
     the sale of large, complex, high capacity systems and with new product
     introductions as well as the uncertainty of customer acceptance of these
     new or enhanced products from either the Company or its competition; risks
     associated with rapidly changing technology and the ability of the Company
     to introduce new products on a timely and cost-effective basis; aggressive
     competition may force the Company to reduce prices; a failure to compensate
     any decrease in the sale of the Company's traditional products with a
     corresponding increase in sales of new products; risks associated with
     changes in the competitive or regulatory environment in which the Company
     operates; risks associated with prosecuting or defending allegations or
     claims of infringement of intellectual property rights; risks associated
     with significant foreign operations and international sales and investment
     activities, including fluctuations in foreign currency exchange rates,
     interest rates, and valuations of public and private equity; the volatility
     of macroeconomic and industry conditions and the international marketplace;

                                       3


     risks associated with the Company's ability to retain existing personnel
     and recruit and retain qualified personnel; and other risks described in
     filings with the Securities and Exchange Commission. These risks and
     uncertainties, as well as others, are discussed in greater detail in the
     filings of the Company with the Securities and Exchange Commission,
     including its most recent Annual Report on Form 10-K and subsequent
     Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. These
     documents are available through the Company, or its website, www.cmvt.com,
     or through the SEC's Electronic Data Gathering Analysis and Retrieval
     system (EDGAR) at www.sec.gov. The Company makes no commitment to revise or
     update any forward-looking statements in order to reflect events or
     circumstances after the date any such statement is made.


                                     PART IV
                                OTHER INFORMATION


(1) Name and telephone number of person to contact in regard to this
notification

Paul Robinson                              (212)         652-6801

 (Name)                                 (Area Code) (Telephone Number)

(2) Have all other periodic reports required under Section 13 or 15(d) of the
Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of
1940 during the preceding 12 months or for such shorter period that the
registrant was required to file such report(s) been filed? If answer is no,
identify report(s).
                                                              |_| Yes |X| No

     The Company has not filed its Annual Report on Form 10-K for the fiscal
year ended January 31, 2006.

(3) Is it anticipated that any significant change in results of operations for
the corresponding period for the last fiscal year will be reflected by the
earnings statements to be included in the subject report or portion thereof?
                                                              |X| Yes |_| No

If so: attach an explanation of the anticipated change, both narratively and
quantitatively, and, if appropriate, state the reasons why a reasonable estimate
of the results cannot be made.

     Revenues for the fiscal quarter ended April 30, 2006 were $373,528,000
     which were significantly greater than revenues of $272,801,000 for the
     fiscal quarter ended April 30, 2005. As disclosed in Part III above, the
     Company is in the process of evaluating the extent of charges for
     stock-based compensation expenses during the periods in question and,
     accordingly, the Company is in the process of evaluating the proper
     accounting for the fiscal quarter ended April 30, 2006 and the necessary
     restatements of its financial statements for the fiscal quarter ended April
     30, 2005, and therefore is unable at this time to provide a reasonable
     estimate and comparison of the results of its operations (other than


                                       4


     revenues) for the fiscal quarter ended April 30, 2006 compared to the
     corresponding 2005 first fiscal quarter results.
