Network Jitter Level Determines how jitter buffer size is adjusted by the SPA9000.
Jitter buffer size is adjusted dynamically. The minimum jitter
buffer size is 30 milliseconds or (10 milliseconds + current
RTP frame size), whichever is larger, for all jitter level settings.
However, the starting jitter buffer size value is larger for
higher jitter levels. This setting controls the rate at which the
jitter buffer size is adjusted to reach the minimum. Select the
appropriate setting: low, medium, high, very high, or
extremely high.
Default: high
Jitter Buffer Adjustment Controls how the jitter buffer should be adjusted. Select the
