[Freeswitch-users] Strange media behavior on WebRTC

[Anthony Minessale]

I set up your test ext here:
https://webrtc.freeswitch.org/sipjs/index.html#8765

And it seems to work.

Try this in vars.xml

<X-PRE-PROCESS cmd="set" data="suppress_cng=true"/>

I don't think the silence suppression works very well in the browser.
