AudioCodes Files Resale Shelf Registration Statement for Previously Issued 2.00% Senior Convertible Notes due 2024

Lod, Israel – April 6, 2005 – AudioCodes Ltd. (NASDAQ: AUDC) , a leading provider of Voice over Packet (VoP) technologies and Voice Network products, today announced that on April 5, 2005 it has filed a resale shelf registration statement on Form F-3 with the Securities and Exchange Commission (the “SEC”), covering resales of $125 million aggregate principal amount of its 2.00% Senior Convertible Notes due 2024 (the “Notes”) and the ordinary shares issuable upon conversion of the Notes.

In November 2004, AudioCodes completed the sale of the Notes in a private placement to the initial purchasers of the Notes. The initial purchasers resold the Notes to qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended.

The registration statement filed with the SEC today has not yet become effective. When the SEC declares the registration statement effective, the selling securityholders named therein may use the prospectus included in the registration statement from time to time to resell their Notes and any ordinary shares issued upon conversion of the Notes. AudioCodes intends to announce when the SEC has declared the registration statement effective.

AudioCodes will not receive any of the proceeds from the resale or the Notes or the ordinary shares issuable upon conversion of the Notes pursuant to the registration statement.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of the Notes or the ordinary shares issuable upon conversion of the Notes in any state in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of any such state.
