Force Jitter Buffer
In the ideal world, when we bridge VoIP channels we don’t
want to jitter buffering on the switch, since the endpoints
can each handle this. However, some endpoints may have
poor jitter buffers themselves, so this option will force to
always jitter buffer, even in this case. The default is “no”.
Max Jitter Buffers A maximum size for the jitter buffer.
Resyncthreshold
When the jitter buffer notices a significant change in delay
that continues over a few frames, it will resync, assuming
that the change in delay was caused by a timestamping
mix - up. The threshold for noticing a change in delay is
measured as twice the measured jitter plus this resync
threshold. Resyncing can be disabled by setting this
parameter to - 1.
Max Jitter Interps
The maximum number of interpolation frames the jitter
buffer should return in a row.
Jitter Target Extra
Number of milliseconds by which the new jitter buffer will
pad its size. The default is 40, so without modification, the
new jitter buffer will set its size to the jitter value plus 40
milliseconds. Increasing this value may help if your network
normally has low jitter, but occasionally has spikes.
