<font size="-1"><font face="Arial">Hi all,<br>
<br>
I have a problem with RTP and NAT.<br>
The scenario is Hosted PBX and Natted phones (yealink):<br>
<br>
Phones (192.168.0.x) - NAT -> FS (public IP) <br>
<br>
When I call FS (for example an IVR) from a Phone, FS send the
RTP to the private address (192.168.0.x) instead to the public
NAT IP.<br>
The registration is ok:<br>

<br>
How I can tell FS to send the RTP Packets to the right address?
I think is needed a "comedia mode" like in Asterisk (or RTPProxy
in openser)...<br>
