Dynamic Jitter
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.
