Description
Dynamic Jitter
Maximum
Jitter Value
60 to 400
ms
The default maximum dynamic jitter
buffer of 300 milliseconds is the
maximum delay tolerable over a high
jitter network.
Default = 300 msec
Optimizat-ion
Factor
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.
Modem Relay
To place modem traffic onto the voip network (an application called “modem relay”),
use Coder G.711 mu-law at 64kbps.
