Administrator‘s Guide for Yealink VC110 Video Conferencing Endpoint
112
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 signal with a minimum number of
bits while retaining quality. This can effectively reduce the frame size and the
bandwidth required for audio transmission.
The audio codec that the endpoint uses to establish a call should be supported by the
server. When placing a call, the endpoint 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 summarizes the supported codecs on the endpoint:
Codec Algorithm Bit Rate Sample Rate Reference
G.722.1c
G.722.1
48 Kbps 32 Ksps RFC 5577
G.722.1c 32 Kbps 32 Ksps RFC 5577
G.722.1c 24 Kbps 32 Ksps RFC 5577
G.722.1 G.722.1 24 Kbps 16 or 32 Ksps RFC 5577
G722 G.722 64 Kbps 16 Ksps RFC 3551
PCMU G.711 64 Kbps 8 Ksps RFC 3551
PCMA G.711 64 Kbps 8 Ksps RFC 3551
Codecs parameters on the endpoint are described below:
Parameter Description Configuration Method

Specifies the enabled codecs for
the endpoint to use.
Note: All support codecs are
enabled on the endpoint by
default.
Web User Interface
Disable Codecs
Specifies the disabled codecs for
the endpoint not to be used.
Web User Interface
To configure codecs via the web user interface:
