[SR-Users] Proxy Registrations offset port

[Robert]

Two different tests I completed:

Test #1 ­ it showed the opensips server
Test #2 ­ it showed the client's public ip address

The issue is not as much RTP ­ but I'm not getting SIP signaling back to the
client.. Which leads me to believe the NAT problem. I'm not even getting
ringingŠ

Maybe I should go ahead and install Kamailio and throw out the OpenSIPs
stuffŠ

Kamailio's default conf is really a good place to start, you just have to
disable the authentication, by commenting the corresponding route.

You can start by looking at a wireshark/tcpdump dump on your PortaOne server
to know where the rtp stream is going, and then troubleshoot accordingly..

On your PortaOne server, what is the location of registered users? Is it
their IP@, or that of OpenSips server?
