Exhibit 99.1


COMVERSE TECHNOLOGY TO DELAY 10-K FILING; RESTATEMENT RELATED TO STOCK-BASED
COMPENSATION EXPECTED

NEW YORK, NY,      April 17, 2006

Comverse Technology, Inc. (NASDAQ: CMVT) today announced that, as a result of
the ongoing review relating to the Company's stock option grants, it will be
filing a Form 12b-25 with the Securities and Exchange Commission (the "SEC")
indicating that its Annual Report on Form 10-K for the fiscal year ended January
31, 2006 will not be filed on its due date of April 17, 2006. The Company will
not seek a 15-day filing extension because it does not believe it could file the
Annual Report by the end of the extension period.

Restatement Related to Stock-Based Compensation Expected

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. 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 notified The NASDAQ Stock Market that it expects not to be in
compliance with the NASDAQ requirements for continued listing under NASDAQ
Marketplace Rule 4310(c)(14) that requires the Company to make on a timely basis
all required filings with the SEC. The Company expects that it will receive a
Staff Determination letter from The NASDAQ Stock Market indicating that, due to
its noncompliance with NASDAQ Marketplace Rule 4310(c)(14), its common stock
would be delisted unless the Company requests a hearing in accordance with the
NASDAQ Marketplace Rules. If the Company receives such a Staff Determination
Letter, the Company intends to request a hearing before the NASDAQ Listing
Qualifications Panel to review the Staff Determination. Under NASDAQ Marketplace
Rules, a request for a hearing stays the delisting action pending the issuance
of a written determination by the NASDAQ Listing Qualification Panel.

The Company intends to issue results for its fourth quarter and the fiscal year
ended January 31, 2006, file its Annual Report on Form 10-K for the fiscal year
ended January 31, 2006 and file any financial statements required to be restated
as soon as practicable after the completion of the Special Committee's review.
