Jitter buffer is a shared data area where voice packets can be collected, stored, and

sent to the voice processor in even intervals. Jitter is a term indicating variations in

packet arrival time, which can occur because of network congestion, timing drift or

route changes. The jitter buffer, located at the receiving end of the voice connection,

intentionally delays the arriving packets so that the end user experiences a clear

connection with very little sound distortion. IP phones support two types of jitter buffers:

fixed and adaptive. A fixed jitter buffer adds the fixed delay to voice packets. You can

configure the delay time for the static jitter buffer on IP phones. An adaptive jitter buffer

is capable of adapting the changes in the network's delay. The range of the delay time

for the dynamic jitter buffer added to packets can be also configured on IP phones.

Procedure

Jitter buffer can be configured using the configuration files or locally.
