AudioCodes Joins with QUALCOMM to Demonstrate VoIP over CDMA2000 1xEV-DO Rev. A at CTIA

Our client, AudioCodes, today announced their collaboration with QUALCOMM® in demonstrating a solution for end-to-end VoIP over CDMA2000® 1xEV-DO Rev. A technology during CTIA Wireless 2006.

The companies are demonstrating a complete solution for VoIP calls using EV-DO Rev. A. By modifying the AudioCodes’ Mediant media gateway product line, AudioCodes now supports the VoIP Enhanced Variable Rate Coder (EVRC) codec, developed by QUALCOMM.

This enables VoIP handsets to communicate transparently over EV-DO Rev. A networks to AudioCodes’ media gateways, allowing VoIP calls between legacy access subscribers and EV-DO Rev. A subscribers. Smart Blanking technology is a way to achieve Discontinuous Transmission (DTX) in packet-based communications which results in increased capacity and greater efficiency in the network.  These EV-DO Rev. A-based technology advancements combined with AudioCodes’ Media Gateways will allow operators to benefit from an extended network capacity, high voice quality and a vast array of VoIP applications.
