Configuring Audio Features
291
This chapter provides information for making configuration changes for the following
audio features:
 Audio Codecs
 Acoustic Clarity Technology
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 following table lists the audio codecs supported by CP860 IP conference phones:
Supported Audio Codecs
Default Audio Codecs
G722, PCMU, PCMA, G729, G723_53,
G723_63, G726_16, G726_24, G726_32,
G726_40, iLBC
