Network Jitter Level
5 settings are available: extremely high, very high,
high, medium, low. This parameter affects how jitter
buffer size is adjusted in the SPA. Jitter buffer size
is adjusted dynamically. The minimum jitter buffer
size is 30 ms or (10 ms + current RTP frame size),
which ever is larger, for all jitter level settings. But
the starting jitter buffer size value is larger for
higher jitter levels. This parameter controls the rate
at which to adjust the jitter buffer size to reach the
minimum. If the jitter level is set to high, then the
rate of buffer size decrement is slower (more
conservative), else faster (more aggressive).
