Codecs
CODEC is an abbreviation of COmpress-DECompress, and is capable of coding or decoding a
digital data stream or signal by implementing an algorithm. The object of the algorithm is to
represent the high-fidelity audio/video signal with a minimum number of bits while retaining
quality. This can effectively reduce the frame size and the bandwidth required for audio/video
transmission.
Audio Codecs
The audio codec that the system uses to establish a call should be supported by the server.
When placing a call, the system will offer the enabled audio codec list to the server and then use
the audio codec negotiated with the called party according to the priority.
