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 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 IP 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.
Supported Audio Codecs
The following table lists the audio codecs supported by each phone model:
