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 Skype for Business phone uses to establish a call should be supported
by the SIP server. When placing a call, the Skype for Business 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.
The following table lists the audio codecs supported by each phone model:
