AudioCodes Mediant(TM) Gateway Achieves Outstanding Voice Quality Results at European Telecommunication Standards Institute Event Only AudioCodes Mediant gateway passed and exceeded all ETSI requirements for VoIP gateways LOD, Israel, Jan. 24 /PRNewswire-FirstCall/ -- AudioCodes (NASDAQ:AUDC), a leading provider of Voice over Packet (VoP) technologies and Voice Network products, announced today that the AudioCodes Mediant(TM) 2000 Media Gateway achieved outstanding voice quality results in the third "Speech Quality Test Event" held by the European Telecommunications Standards Institute (ETSI) in June and September, 2004. Out of all VoIP gateways submitted for testing by the ten vendors that participated in the event, AudioCodes Mediant 2000 was the single product that passed and exceeded the requirements in all test categories. The aim of the third ETSI VoIP Speech Quality Test Event was for manufacturers of VoIP gateways to have their equipment tested under controlled IP network conditions including end-to-end as well as mouth-to-ear scenarios and to measure, analyze and compare speech quality parameters, creating a benchmark comparison of the competing products. "Voice Quality has always been the cornerstone of our VoIP enabling technology and networking products. Achieving excellent results in the very important ETSI VoIP Speech Quality Test Event is yet another demonstration of our commitment to technology excellence", said Shabtai Adlersberg, President and CEO of AudioCodes. "Voice quality continues to be one of the key factors to successful penetration of VoIP in the telecom marketplace." "Voice quality is essential for VoIP to continue expanding and being deployed in the most demanding networks. Achieving the highest levels of voice quality requires technical expertise, commitment to quality, and also a critical mass of field deployments in many diverse conditions, networks and regions," said Jeremy Duke, President and CEO of Synergy Research. "In the ETSI test, AudioCodes proved it had the skill, quality commitment and VoIP field proven experience to achieve the leading voice quality offering. AudioCodes customers and the industry will benefit from this achievement."
