Transcoding server

Implemented as an application server controlled by the VoipSwitch main platform. It enables VoipSwitch to route and connect calls when the call origination and termination have no common audio codec. The transcoding process is fully transparent for end users.

The server can run as a standalone application or in a cluster configuration with VoipSwitch distributing transcoding tasks among multiple instances.

The transcoding server can decode and then encode any of the codecs supported by VoipSwitch.

The most widely used codecs include:

G729, g711u and a, AMR NB, AMR WB, g722, Speex, Opus, Silk, GSM
