Description

 

 

 

Dynamic

Jitter

 

 

 

 

Maximum

60 to 400

The default maximum dynamic jitter

Jitter Value

ms

buffer of 300 milliseconds is the

 

 

maximum delay tolerable over a high

 

 

jitter network.

 

 

Default = 300 msec

 

 

 

Optimizat-ion

0 to 12

The Optimization Factor determines

Factor

 

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.
