[Freeswitch-dev] Verto communicator client not working on Edge when we use our freeswitch server

Thanks for your comments.
The thing is that the SAME client (which only uses Google STUN server) WORKS on Edge when connecting to the Freeswitch server hosted in cantina.freeswitch.org
... and does NOT work when connecting to our own Freeswitch server.

So how come it is working on cantina.freeswitch.org ??
No turn server is being used by the peer connection object, but it still works!

Any ideas?

You need to use turn with edge.  They didn't implement stun.  Or wait for edge to become Chrome since that is their plan.

Dear members,
. We can use the verto communicator client to join a conference handled by our own Freeswitch server and using the default 'stun:stun.l.google.com:19302<http://stun.l.google.com:19302>' Google STUN 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.
. When using Chrome we can see one of the ICE Candidates DOES have the client public IP.
. But when running the client on Edge we do NOT see such candidate.
. What it is interesting is that if we don't use our Freeswitch server but the one hosted in cantina.freeswitch.org<http://cantina.freeswitch.org> then the verto client CAN connect ok and we get audio+video (although we noticed that even in this case we still not see the ICE Candidate with the client public IP in the SDP offer).
. So my question is if the Freewitch server in cantina.freeswitch.org<http://cantina.freeswitch.org> is doing something "special" to retrieve the client public IP from the signaling messages or something like that.
. By the way, we already set the following params in the verto conf:

<param name="apply-candidate-acl" value="localnet.auto"/>
<param name="apply-candidate-acl" value="wan_v4.auto"/>
<param name="apply-candidate-acl" value="rfc1918.auto"/>
<param name="apply-candidate-acl" value="any_v4.auto"/>

If you can give us any hints it would be much appreciated.
