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.
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 may
help if your network normally has low jitter, but occasionally has spikes.

Max Call Number
The ‘maxcallnumbers’ option limits the amount of call numbers allowed for
each individual remote IP address. Once an IP address reaches its call
number limit, no more new connections are allowed until the previous ones
close. This option can be used in a peer definition as well, but only takes
effect for the IP of a dynamic peer after it completes registration.
MaxCallNumbers_Nonvalidated The ‘maxcallnumbers-nonvalidated’ is used to set the combined number of
call numbers that can be allocated for connections where call token
validation has been disabled. Unlike the ‘maxcallnumbers’ option, this limit
is not separate for each individual IP address. Any connection resulting in a
non-call token validated call number being allocated contributes to this
limit. For use cases, see the call should be sufficient in most cases.
