[Freeswitch-users] How can we make Freeswitch work with a verto client running on Edge?

[Gregor Nanger]

Alejandro, Edge is not fully compliant with Webrtc and hence verto is not
working. I admire your eagerness and welcome you and I think someone just
have to tell you this. But if you are in doubt, try to find solution and
community will be thankfull. Don't take my post as negative, but just to
spare you some time.

Br, Gregor
