Hello.
I am connecting to a local PJSIP conference using an external RTP stream
that has the G-711 codec and a ptime value of 60ms. These parameters in the
equipment do not change. This RTP stream is played in the sound card, which
is also connected to the local conference, without problems. But when I
connect another computer with PJSIP to the local conference and switch this
RTP stream to it, then on the remote device with PJSIP this RTP stream is
played with impulse noise. I recorded this stream in wireshark and uploaded
it to audacity. The recording shows that every 20ms the sound disappears
for 2ms and I hear it like impulse noise. PJSIP version 1.16. Please help
me get rid of this problem.
