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

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' 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 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 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.
