<font size="2" style="font-size: 11pt;">Hello all,<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>

<div>Thanks for your comments.</div>
<div>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</div>
<div>... and does NOT work when connecting to our own Freeswitch server.</div>
<div><br>
</div>
<div>So how come it is working on cantina.freeswitch.org ??</div>
<div>No turn server is being used by the peer connection object, but it still works!</div>
<div><br>
</div>
<div>Any ideas?</div>

<div>Dear members,<br>
. We can use the verto communicator client to join a conference handled by our own Freeswitch server and using the default 'stun:<a href="http://stun.l.google.com:19302">stun.l.google.com:19302</a>' Google STUN 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>
. When using Chrome we can see one of the ICE Candidates DOES have the client public IP.<br>
. But when running the client on Edge we do NOT see such candidate.<br>
. What it is interesting is that if we don't use our Freeswitch server but the one hosted in
<a href="http://cantina.freeswitch.org">cantina.freeswitch.org</a> 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).<br>
. So my question is if the Freewitch server in <a href="http://cantina.freeswitch.org">
cantina.freeswitch.org</a> is doing something "special" to retrieve the client public IP from the signaling messages or something like that.<br>
. By the way, we already set the following params in the verto conf:<br>
<br>
<param name="apply-candidate-acl" value="localnet.auto"/><br>
<param name="apply-candidate-acl" value="wan_v4.auto"/><br>
<param name="apply-candidate-acl" value="rfc1918.auto"/><br>
<param name="apply-candidate-acl" value="any_v4.auto"/> <br>
<br>
If you can give us any hints it would be much appreciated.<br>
Regards,<br>
Alex </div>
