[OpenSIPS-Users] how to forward SIP messages?

[Christian Cambier]

Hello.

Direct registration (not passing via the proxy) with extension:
5006 at 10.0.2.16 works
(see SIP trace 1)


Registration with the same extension but via the proxy doesn't work

(see SIP trace 2)

I've added in the proxy as you suggested:
         record_route();

         rewritehostport("10.0.2.16:5060");

         t_relay();

         exit;


Interesting to note though is that the message has been forwarded to the
PBX (see Server-header in the response) but the PBX didn't accept the
registration
