[Freeswitch-users] Broken silence with webrtc

Your findings contradict each other so much, I recommend you start over
from scratch.
Backup your configs.  update to the latest master version of FS.  If you
are on 1.4, nothing new will be done to mitigate webrtc issues.  Set up a
box with the default configurations and retest.

you may also want to try putting <X-PRE-PROCESS cmd="set" data=
"suppress_cng=true"/>  in vars.xml
