4.6.1.8.2 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 hands-free/chas-
sis). 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.audioProfile.x.jitterBufferShrink 10, 20, 30, ...
(multiple of
10) The absolute minimum duration time (in
milliseconds) of RTP packet Rx with no
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).

The largest jitter buffer depth to be sup-
ported (in milliseconds). Jitter above
this size will always cause lost packets.
This parameter should be set to the
smallest possible value that will support
the expected network jitter.
