Attribute	Permitted	Interpretation
	Values
voice.audioProfile.x.jitterBufferMin	40, 50, 60, ...	The smallest jitter buffer depth (in milli-
	(multiple of	seconds) that must be achieved before
	10)	play out begins for the first time. Once
		this depth has been achieved initially, the
		depth may fall below this point and play
		out will still continue. This parameter
		should be set to the smallest possible
		value which is at least two packet pay-
		loads, and larger than the expected short
		term average jitter.
voice.audioProfile.x.jitterBufferShrink	10, 20, 30, ...	The absolute minimum duration time (in
	(multiple of	milliseconds) of RTP packet Rx with no
	10)	packet loss between jitter buffer size
		shrinks. Use smaller values (1000 ms) to
		minimize the delay on known good net-
		works. Use larger values to minimize
		packet loss on networks with large jitter
		(3000 ms).
voice.audiProfile.x.jitterBufferMax	> jitterBuf-	The largest jitter buffer depth to be sup-
	ferMin,	ported (in milliseconds). Jitter above
	multiple of	this size will always cause lost packets.
	10,	This parameter should be set to the
	<=500 for IP	smallest possible value that will support
	500 and IP	the expected network jitter.
	600,
	<= 160 for IP
	300

4.6.1.6.2 Volume Persistence <volume/>

The user’s selection of the receive volume during a call can be remembered between calls. This can be configured per termination (handset, headset and handsfree/chassis). In some countries regulations exist which dictate that receive volume should be reset to nominal at the start of each call on handset and headset.

voice.volume.persist.handset	0, 1	0	If set to 1, the receive volume will be

			If set to 0, the receive volume will be
voice.volume.persist.handsfree	0, 1	1	reset to nominal at the start of each
			call.
