                  Certification of Periodic Report Pursuant to
                   Section 302 of Sarbanes-Oxley Act of 2002

I, Sergio Moren, certify that:

1.       I have reviewed this annual report on Form 10-K of Cortelco Systems
         Puerto Rico, Inc. ("Registrant");

2.       Based on my knowledge, this annual 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 annual report;

3.       Based on my knowledge, the financial statements, and other financial
         information included in this annual 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 annual report.

4.       The registrant's other certifying officers and I are responsible for
         establishing and maintaining disclosure controls and procedures (as
         defined in Exchange Act Rules 13a-15(e) and 15d-15(e) for the
         registrant and 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
          Registrant, including its consolidated subsidiaries, is made known to
          us by others within those entities, particularly during the period in
          which this report is being prepared;

         b)   evaluated the effectiveness of the Registrant'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

         c)   disclosed in this report any change in the Registrant's internal
          control over financial reporting that occurred during the Registrant's
          fourth fiscal quarter that has materially affected, or is reasonably
          likely to materially affect, the Registrant's internal control over
          financial reporting; and

5.       The registrant's other certifying officers and I have disclosed, based
         on our most recent evaluation, of internal control over financial
         reporting, to the Registrant's auditors and the audit committee of the
         Registrant's board of directors:

         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 Registrant'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 Registrant's
          internal controls over financial reporting.
