How can we make Freeswitch work with a verto client running on Edge?
Hello all, We can use the verto communicator client to join a conference handled by our own Freeswitch server. It works on Chrome, Firefox and Opera, on which we can connect ok and get audio+video. But it does NOT work on Edge. The candidates Edge provides are the following: candidate:1 1 UDP 2130706431 192.168.0.7 63832 typ host candidate:2 1 TCP 1684798975 192.168.0.7 63832 typ srflx raddr 192.168.0.7 rport 63832 tcptype active So for for every local IP, Edge generates 2 candidates: 1 host candidate, and 1 srflx candidate. The srvflx candidate is built wrong on purpose (transport address == related address). I guess they do that so that when the ICE connection checks take place, the server side can "learn" a new prflx candidate (see RFC5245, section 7.2.1.3) I have tested the same scenario using a server which makes use of the libnice library for the ICE implementation, and it works!!! No TURN server is being used, no STUN server is being used, the candidates Edge sends are the 2 above (which do not contain a public IP) and still the server generates a prflx candidate and the connection is established perfectly. But when using our Freeswitch server (which does not make use of the libnice library for ICE) the connection does not work. Then again, the funny thing is that if we use the cantina.freeswitch.org Freeswitch server, then it DOES work! So there must be something in the code/configuration that could be done so that the Freeswitch server can "learn" a prflx candidate from those Edge is sending out. Could anyone help us? Alex
Hello, Please do not repost your questions. Try to use Chrome or wait while Edge will become Chrome too as Anthony suggested. Regards, Alex On Thu, Jan 3, 2019 at 6:10 AM Alejandro Castera <Alejandro.Castera@on24.com> wrote:

Sorry but it is perfectly ok to post my question on the users' list, since the devs were of no help whatsoever. Maybe a user has run into the same problem and has found a solution to it.

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.
