forward does what you want, so skip rewritehostport. g-)

Thanks, this only partialy solved the problem.
What I am looking for is function which can send (forward) message to a specified IP:port based on URI but not changing URI itself. rewritehostport() and t_relay() unfortunately does it. I have found someting like forward() but not know how to use it. What is the difference between: rewritehostport("192.168.1.2:5060"); t_relay(); and rewritehostport("192.168.1.2:5060"); forward(forward(uri:host, uri:port); ?
Thanks, Andrzej
Quoting "Greger V. Teigre" greger@teigre.com:
Try to just t_relay in loose route...
And if that does not work, what type of messages are looped back? 200 OKs? ACKs? BYEs? g-)

All,
I am trying to configure SER to work as SIP proxy (not registar and not redirect). I tried to modify simple ser.cfg which comes with SER by adding one line in route[0]:
rewritehostport("192.168.1.2:5060");
This unfortunately doesn't work. The message to my SIP server 192.168.1.2 are indeed forwarded. But message comming back from 192.168.1.2 are looped by my SIP proxy (192.168.1.3) back to SIP server (192.168.1.2).
Can someone help me? Or send a working cfg for SIP proxy, I cannot find any.
