Network Jitter Level
4 settings are available: 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).
