[SR-Users] Proxy Registrations offset port

Tue Mar 20 22:36:22 CET 2012

I've spent a significant amount of time now jacking with configurationsŠ

Maybe I should re-state what I'm trying to doŠ

I'm trying to establish an SBC / UpperRegistration SBCŠ

The goal  is to listen on a port other than 5060 and relay the registration
to the actual proxy.

I.e. IP Phone ---> Kamailio (port 8080) ----> Sip proxy (port 5060)

I've tried all combinations of rewritehostport / t_replicate etcŠ

The best I get is an attempt to register followed by an unauthorized with
request for digest auth..

I don't want to store any credentials in Kamailio  I just want to act as an
offset port for users who cannot reach 5060Š

OpenSBC was working for this  however the registrations were timing out and
not renewing

No wonder your signallin is not reaching the final client.

I didnt't suggest to throw OpenSips. NAT handling is delicate woth proxies.

Start by looking at some wireshark dump to see what's wrong.
