even with that I cannot engage the RTPPROXY.
My Kamailio version is 3.1.3 and the config file is plain , from
installation.
Any ideas?
Thank you Alex

I have a Kamailio with =A0RTPoxy configured. The purpose is to pass the<br>
RTP from this server.<br>
When I make calls behind NAT the RTProxy seems to be engaged but in<br>

Is there anything wrong with the idea or I'm missing something in the<b=

That would be difficult to know without seeing your configuration.<br>
