Description

 

 

Dynamic

Jitter

 

 

 

 

Dynamic

 

 

Dynamic Jitter defines a minimum

 

 

Jitter Buffer

 

 

and a maximum jitter value for

 

 

 

 

 

voice communications. When

 

 

 

 

 

receiving voice packets from a

 

 

 

 

 

remote MultiVOIP, varying delays

 

 

 

 

 

between packets may occur due to

 

 

 

 

 

network traffic problems. This is

 

 

 

 

 

called Jitter. To compensate, the

 

 

 

 

 

MultiVOIP uses a Dynamic Jitter

 

 

 

 

 

Buffer. The Jitter Buffer enables the

 

 

 

 

 

MultiVOIP 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 between

 

 

 

 

 

MultiVOIP gateways.

 

 

 

 

 

 

 

 

Minimum

60 to 400

 

The minimum dynamic jitter buffer

 

 

Jitter Value

ms

 

of 60 milliseconds is the minimum

 

 

 

 

 

delay that would be acceptable over

 

 

 

 

 

a low jitter network.

 

 

 

 

 

Default = 150 msec
