Jitter Buffer
A jitter buffer is used at the receiving equipment to store incoming RTP packets, re-align them in terms of
timing and check they are in the correct order. If some arrive slightly out-of-sequence then, provided it is
large enough, the jitter buffer can put them back into the right sequence. However, for this to work the
receiving device must delay the audio very slightly while it checks and reassembles the packet stream.
Below are the Jitter buffer Settings to control the size of the buffer and its implementation mode:
Table 37: Jitter Buffer Settings
SIP Jitter Buffer
Enable Jitter Buffer
Select to enable jitter buffer on the sending side of the SIP channel. The
default setting is "No".
Jitter Buffer Size
Configure the time (in ms) to buffer. This is the jitter buffer size used in
"Fixed" jitter buffer or used as the initial time for "adaptive" jitter buffer. The
default setting is 100.
