If you experience broken or choppy speech at either end of the call, or the dial
tone sounds choppy, use the volume controls on the MVC 2050 toolbar to
adjust volume while using the MVC 2050.
If you experience reduced audio clarity in the receive audio stream, increase
the Audio clarity setting. This increases the number of audio buffers used to
process incoming audio. If the delay is too large, you can decrease the Audio
clarity setting.

Nortel Mobile Voice Client 2050
Description
NetEQ packet loss concealment
software is the default mode of
operation.
A Jitter Buffer is used to minimize a
change in rate for arriving voice
frames. The Jitter Buffer sends
voice frames to your PDA sound
system at a fixed rate. The rate of
arrival of voice frames is variable.
The value of "jitter" is the normal
number of voice frames the
application should have in its jitter
buffer.
