                            CERTIFICATION PURSUANT TO
                             18 U.S.C. SECTION 1350,
                             AS ADOPTED PURSUANT TO

              PURSUANT TO REGULATION SS.240.15D-14 AS PROMULAGATED
                    BY THE SECURITIES AND EXCHANGE COMMISSION

I, Jerome R. Mahoney, President, Chief Executive Officer and Principal
Accounting Officer of iVoice, Inc. certify that:

1)   I have reviewed this quarterly report on Form 10-QSB of iVoice, Inc.;

2)   Based on my knowledge, this report does not contain any untrue statement of
     a material fact or omit to state a material fact necessary to make the
     statements made, in light of the circumstances under which such statements
     were made, not misleading with respect to the period covered by this
     report;

3)   Based on my knowledge, the financial statements, and other financial
     information included in this quarterly report, fairly present in all
     material respects the financial condition, results of operations and cash
     flows of the registrant as of, and for, the periods presented in this
     quarterly report;

4)   I have:

      (a)  Designed such disclosure controls and procedures, or caused such
           disclosure controls and procedures to be designed under our
           supervision, to ensure that material information relating to the
           small business issuer, including its consolidated subsidiaries, is
           made known to me by others within those entities, particularly during
           the period in which this report is being prepared;

      (b)  Intentionally omitted;

      (c)  Evaluated the effectiveness of the small business issuer's disclosure
           controls and procedures and presented in this report our conclusions
           about the effectiveness of the disclosure controls and procedures, as
           of the end of the period covered by this report based on such
           evaluation; and

      (d)  Disclosed in this report any change in the small business issuer's
           internal control over financial reporting that occurred during the
           small business issuer's most recent fiscal quarter (the small
           business issuer's fourth fiscal quarter in the case of an annual
           report) that has materially affected, or is reasonably likely to
           materially affect, the small business issuer's internal control over
           financial reporting; and

5)   I have disclosed, based on our most recent evaluation of internal control
     over financial reporting, to the small business issuer's auditors and the
     audit committee of the small business issuer's board of directors (or
     persons performing the equivalent functions):

      (a)  All significant deficiencies and material weaknesses in the design or
           operation of internal control over financial reporting which are
           reasonably likely to adversely affect the small business issuer's
           ability to record, process, summarize and report financial
           information; and

      (b)  Any fraud, whether or not material, that involves management or other
           employees who have a significant role in the small business issuer's
           internal control over financial reporting.
