Jitter Buffer
Global default as to whether you want the jitter buffer at all
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.
Max Jitter Buffers
A maximum size for the jitter buffer
Resyncthreshold
When the jitter buffer notice 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 interpolation 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 this many
interpolations. This prevents interpolating throughout a long
silence.
