<div class="moz-cite-prefix">Hi Gonzalo,<br>
<br>
I see the problem.<br>
<br>
Currently the MCU enables the STUN binding and the NAT traversal
when the ip in the C line is a private IP address in the C line
which is not in the local net configured for the media mixer. If
the clients sends a public ip address then, that address is used
and the STUN/NAT traversal is disabled.<br>
<br>
I have been working with mobicents javascript client and I don't
have this problem, as it doesn't wait for the the ice candidates
to send the first INVITE immediately and the C line has a 0.0.0.0
which triggers the STUN in the MCU. Is it possible to disable the
ICE candidate gathering in sipml5 by leaving the stun server ip
address empty? That would work.<br>
<br>
<br>
Best regards<br>
Sergio<br>
