Exhibit 99.1


             STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE OFFICER AND
                          PRINCIPAL FINANCIAL OFFICER
       REGARDING FACTS AND CIRCUMSTANCES RELATING TO EXCHANGE ACT FILINGS


I, Kobi Alexander, state and attest that:

      (1) To the best of my knowledge, based upon a review of the covered
      reports of Comverse Technology, Inc., and, except as corrected or
      supplemented in a subsequent covered report:

      o     no covered report contained an untrue statement of a material fact
            as of the end of the period covered by such report (or in the case
            of a report on Form 8-K or definitive proxy materials, as of the
            date on which it was filed); and

      o     no covered report omitted to state a material fact necessary to make
            the statements in the covered report, in light of the circumstances
            under which they were made, not misleading as of the end of the
            period covered by such report (or in the case of a report on Form
            8-K or definitive proxy materials, as of the date on which it was
            filed).

      (2) I have reviewed the contents of this statement with the Company's
      audit committee.

      (3) In this statement under oath, each of the following, if filed on or
      before the date of this statement, is a "covered report":

      o     Annual Report on Form 10-K for the fiscal year ended January 31,
            2002 of Comverse Technology, Inc.;

      o     all reports on Form 10-Q, all reports on Form 8-K and all definitive
            proxy materials of Comverse Technology, Inc. filed with the
            Commission subsequent to the filing of the Form 10-K identified
            above; and

      o     any amendments to any of the foregoing.
