Description
Determines how jitter buffer size is adjusted by the
SPA9x2. 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.
Defaults to high.
Controls how the jitter buffer should be adjusted. Select
the appropriate setting: up and down, up only, down
only, or disable.
Defaults to up and down.
