Field Name	Values	Description
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.
Minimum	60 to 400	The minimum dynamic jitter buffer of
Jitter Value	ms	60 milliseconds is the minimum delay
		that would be acceptable over a low
		jitter network.
		Default = 150 msec
