Force Jitter
Buffer

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.
Max Jitter
Buffers
A maximum size for the jitter buffer.
Resyncthreshold
When the jitter buffer notices a significant change in delay that continue 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.
Max Jitter
Interps
The maximum number of interpolations frames the jitter buffer should return in a row.
Since some clients do not send CNG/DTX frames to indicate silence, the jitter buffer
will assume silence has begun after returning these many interpolations. This
