I am using RTP Proxy with the following command:

Nov 28 13:04:09 ubuntu /usr/local/kamailio-3.1/sbin/kamailio[2770]: INFO: rtpproxy [rtpproxy.c:1403]: rtp proxy <udp:127.0.0.1:7722> found, support for it re-enabled

If I trace an attempted call on port 7722, I see there is no activity on port 7722.

My firewall is open to port 7722.

Thanks
