Video Codecs
CODEC is an abbreviation of COmTap-DEComTap, capable of coding or decoding a digital data stream or signal
by implementing an algorithm. The objective of the algorithm is to represent the high-fidelity video signal with
minimum number of bits while retaining the quality.This effectively reduces the frame size and the bandwidth
required for the video transmission.
The video codec that the IP phone uses to establish a call should be supported by the SIP server.When placing a
call, the IP phone offers the enabled video codec list to the server and then use the video codec negotiated with the
called party according to the priority.
RTPmap
Codecs and their priorities are configurable on a per-line basis. The attribute “rtpmap” is used to define a mapping
from RTP payload codes to a codec, clock rate and other encoding parameters.
The following table lists the video codecs supported by IP phone:
