Description
Dynamic Jitter defines a minimum and a maximum jitter value for
voice communications. When receiving voice packets from a
remote
source
network traffic problems. This is called Jitter. To compensate, the
TalkAnytime unit uses a Dynamic Jitter Buffer. The Jitter Buffer
enables the TalkAnytime unit 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 on voip calls.
60 to 400
The minimum dynamic jitter buffer of 60 milliseconds is the
ms
minimum delay that would be acceptable over a low jitter network.
Default = 150 msec
60 to 400
The maximum dynamic jitter buffer of 400 milliseconds is the
ms
maximum delay tolerable over a high jitter network.
Default = 300 msec
0 to 12
The Optimization Factor determines how quickly the length of the
Dynamic Jitter Buffer is changed based on actual jitter encountered
on the network. Selecting the minimum value of 0 means low voice
delay is desired, but increases the possibility of jitter-induced voice
quality problems. Selecting the maximum value of 12 means
highest voice quality under jitter conditions is desired at the cost of
increased voice delay.
Default = 7.
