I've spent a significant amount of time now jacking with configurations
Maybe I should re-state what I'm trying to do
I'm trying to establish an SBC / UpperRegistration SBC
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 etc
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 5060
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.

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

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?

Thank you so much for answering.. The folks at
the other place don't want to
help.
We have a PortaOne SIP platform It does everything It's listening on port
5060 public ip..
We want to deploy Kamailio or some derivative of SER to listen on PUBLIC port
other than 5060 for our customers who cannot reach 5060.
Using a very simple rewritehostport statement I was successful in getting
the registration to pass through. I.e. Registered my Aastra and X-Lite to
port 8080 and saw registration in PortaOne.
I do not want K/SER to do actual auth / registration I.e. I do not care who
tries to use it I want final registration to be PortaOne That's why I
think the simple rewritehostport worked well. OpenSIPS was not doing any auth
just simply passing it on.
Our PortaOne was handling RTP Proxy so during an outbound call I was
getting 2 way audio no problem.
However when an inbound call would come in from PortaOne it was being
delivered to OpenSIPS and looks like Opensips was reporting 401 Unauthorized.
The Aastra / X-Lite are NAT It's possible that either I need to look at
nathlper closer or that I misconfigured something somewhere.
I guess I'm not fluent enough in the configs and options to get a good
config.

Hi Robert,
I had the same feeling about O***sips community.....
I have a similar setup. A proxy that listens on port other than 5060,
forwarding to other servers on 5060.
If you can better define better your problem with your setup, maybe we can
help you better.
Is your server listening only on one port 8080? Is your server behind NAT or
does it have a public IP @ on the interface it's listening on? What is the
exact problem with inbound calls? Are you doing record-route? Do you forward
only registrations, or are your handling invites as well? What server listens
on port 5060? Another Kamailio server? Does it handle clients behind NAT?
You should know that Kamailio is a SIP server, not a PBX/sofswitch/SBC as
Asterisk or Freeswitch.
If you define better your problem, and send me your config file (by private
email if you like), I may look at it.

I've been playing with OpenSIPS and am
willing to change over if it means
I'll get a more informed answer from this community..
I need to set up a proxy forwarding server that can listen on a port other
than 5060 I.e. 8080 and forward the registration requests to another Voip
platform we have that is running on 5060.
I've been able to this under OpenSIPS but I'm having issues with inbound
calls. It could be a NAT issue.
Basically listen on 8080 forward any and all registrations to x:5060
which I've done using rewritehostport
Anyone have any good example configs for this? I'm a n00b at this OpenSER
stuff but have been around asterisk / freeswitch / portaone for a while.
Thanks in advance
