Overview
AudioCodes develops a comprehensive line of voice over packet (VoP) processors and modules, suitable for OEM implementations of voice communications over packet networks.
Each processor features low bit rate vocoders, state-of-the-art echo cancellation and T.38 compliant fax relay. In addition, our field-proven, feature-rich software enables solutions to be developed rapidly, thereby minimizing time-to-market. The VoP chip processors are suitable for high and medium density VoIP gateways, residential gateways and integrated access devices (IAD), and for end-user applications such as small gateways, analog telephony adaptors (ATA) and IP phones.
