[Freeswitch-users] Audio Issue: Digitized background beep when speaking

[Michael Collins]

It would help if you could isolate whether or not the audio is coming from
a particular call leg. I would use pcapsipdump for this since it creates
separate files for each SIP call on the system. Also, if you are using
FreeTDM then you'll also need to use the ftdm trace command to capture the
audio from the TDM card.

Once you know where the rogue audio is originating then you can start
looking for a solution.
