Field Name Values Description

Dynamic Jitter

Maximum

Jitter Value

60 to 400

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.
