Hi list, I bridge a call with ptime 10 on one side and ptime 20 on the other. PCM codec on both sides, so no transcoding. The issue I face is that when a 20 ms packet arrives it is immediately sent out as two 10ms packets. And then nothing for 20ms until next packet arrives. Delta time between sent our packets are either 0 or 20 ms, never 10ms as one would expect. The result is choppy audio since we introduce jitter. Could this be avoided somehow? I am using Freeswitch 1.6.12 on CentOS 7.2. Best regards, Jan Blom

As far as I remember, bridged RTP frames are sent out as soon as they are ready, without looking at the timer, so it totally makes sense... kind of :) On 1 Nov 2016 15:59, "Brian West" <brian@freeswitch.org> wrote:
