Determines how jitter buffer size is adjusted by the ATA. 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 setting: high
