[Freeswitch-users] jitter buffer during bridge call

Wed Feb 22 15:16:59 MSK 2017

I removed all that sonus stuffs, and added in the bridge string :
{jitterbuffer_msec=1p,rtp_jitter_buffer_during_bridge=true,sip_secure_media=true,sdp_m_per_ptime=true,hangup_after_bridge=true}

But still the same: in leg A I see a jitter of max 2 ms and avg of 1 and on
leg B 26 ms max and avg of 16.
