VoIP Processors

Comprehensive line of voice over packet (VoP) processors and modules

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.

Benefits

  • Field-proven technology with millions of channels deployed
  • Feature-rich algorithms and software covering all VoIP functions and applications
  • Integrated DSP (VoIP processors) and SoC (system on chip)
  • Scalable from single channel to hundreds of channels per single chip
