Dynamic Jitter Buffer
Parameters
Dynamic
Jitter Buffer
Dynamic Jitter defines a minimum
and a maximum jitter value for
voice communications. When
receiving voice packets from a
remote
MultiVOIP, varying delays
between packets may occur due to
network traffic problems. This is
called Jitter. To compensate, the
MultiVOIP uses a Dynamic Jitter
Buffer. The Jitter Buffer enables the
MultiVOIP to wait for delayed voice
packets by automatically adjusting
the length of the Jitter Buffer
between configurable minimum
and maximum values. An
Optimization Factor adjustment
controls how quickly the length of
the Jitter Buffer is increased when
jitter increases on the network. The
length of the jitter buffer directly
effects the voice delay between
MultiVOIP gateways.
The default minimum dynamic
jitter buffer of 60 milliseconds is the
minimum delay that would be
acceptable over a low jitter network.
The default maximum dynamic
jitter buffer of 300 milliseconds is
the maximum delay tolerable over a
high jitter network.
