Dynamic Jitter

Dynamic		Dynamic Jitter defines a minimum and
Jitter Buffer		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.
		The default minimum dynamic jitter
		buffer of 60 milliseconds is the
		minimum delay that would be
		acceptable over a low jitter network.
		The default maximum dynamic jitter
		buffer of 300 milliseconds is the
		maximum delay tolerable over a high
		jitter network.

Jitter Value	ms	buffer of 60 milliseconds is the
