[Freeswitch-users] Strange media behavior on WebRTC

Yeah, I saw sipjs vs jssp but I pointed my own jssip client to your example
and there was no noise, so it's not the client.  I also am setting my stun
servers array to empty to speed up the connection but that also does not
seem to matter.  I'll keep digging.
