EXHIBIT 99.1

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


I, Donald K. Peterson, state and attest that:

(1)  To the best of my knowledge, based upon a review of the covered reports of
     Avaya 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    the Annual Report on Form 10-K for the fiscal year ended September 30,
          2001 of Avaya Inc;

     o    all reports on Form 10-Q, all reports on Form 8-K and all definitive
          proxy materials of Avaya 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.
