[Freeswitch-users] RTP Wrong Timestamps and audio hiccups in conferencing output

[Cal Leeming [Simplicity Media Ltd]]

As mentioned by Michael, without seeing the wireshark dumps it will be
difficult to diagnose what is happening (however even if you upload the
dump, it will require someone to take time out to review and analyse).

Best thing to do is analyse the wireshark and try everything you can think
of to diagnose/debug the problem, then upload the logs+wireshark along with
a full debrief of what you have tried so far.

This will greatly increase the chance of others taking time out to help you
with this.
