Voice/Fax Parameter Definitions (cont’d)
Field Name Values Description
Dynamic Jitter
Maximum
Jitter Value
60 to 400
ms
The maximum dynamic jitter buffer
of 400 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.
