[Freeswitch-users] Strange media behavior on WebRTC

Hi Anthony,

I dug further and I can reproduce the issue on a completely different VM
(Debian on Windows host).  I installed the latest FS master and even
switched to the vanilla conf to eliminate the possibility of my config
causing this issue.

It's still happening.  If you have time to look into this some more, I'll
be happy to upload my whole VM for someone to take a look at.
