Audio Codecs
CODEC is an abbreviation of COmpress-DECompress, 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 signal with a minimum
number of bits while retaining the quality. This can effectively reduce the frame size and the bandwidth required for
audio transmission.
The audio codec that the phone uses to establish a call should be supported by the SIP server. When placing a call, the
phone 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.
