Hello all,<br>
<br>
We can use the verto communicator client to join a conference handled by our own Freeswitch server.<br>
It works on Chrome, Firefox and Opera, on which we can connect ok and get audio+video.<br>
But it does NOT work on Edge.<br>
<br>
The candidates Edge provides are the following:<br>
<br>
candidate:1 1 UDP 2130706431 192.168.0.7 63832 typ host<br>
candidate:2 1 TCP 1684798975 192.168.0.7 63832 typ srflx raddr 192.168.0.7 rport 63832 tcptype active<br>
<br>
So for for every local IP, Edge generates 2 candidates: 1 host candidate, and 1 srflx candidate.<br>
The srvflx candidate is built wrong on purpose (transport address == related address).<br>
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)<br>
<br>
I have tested the same scenario using a server which makes use of the libnice library for the ICE implementation, and it works!!!<br>
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.<br>
<br>
But when using our Freeswitch server (which does not make use of the libnice library for ICE) the connection does not work.<br>
Then again, the funny thing is that if we use the cantina.freeswitch.org Freeswitch server, then it DOES work!<br>
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.<br>
<br>
Could anyone help us?<br>
Alex
