[Freeswitch-users] jitter buffer during bridge call

Tue Feb 28 18:10:53 MSK 2017

I tested now with 20bcb2edef02e95118df76f0ecdd8a64471d1e0a (last master)
and works nice . There is no jitter as output Is master stable for
production ?

Because 1.6.x seems that has this bug, also in 1.2.x which is dead for long
time it's fine
