Dynamic	Jitter
Dynamic		Dynamic Jitter defines a minimum and a maximum jitter
Jitter Buffer		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. The length of the jitter buffer directly
		effects the voice delay between MultiVOIP gateways.
Minimum	20 to 400	The minimum dynamic jitter buffer of 20 milliseconds is the
Jitter Value	ms	minimum delay that would be acceptable over a low jitter
		network.
		Default = 20 msec
Maximum	20 to 200	The maximum dynamic jitter buffer of 200 milliseconds is
Jitter Value	ms	the maximum delay tolerable over a high jitter network.
		Default = 200 msec
Initial Jitter	20 – 200	The starting value (in ms) of the Jitter Buffer. This value
Value	ms	will change itself from the starting value depending on the
	default =	needs of the jitter buffer. For example, if you set the initial
	20 ms
		value at 100, it may end up scaling itself down to 20 or up to
		200 to meet the needs of operating conditions.
