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 do 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
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.

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.

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?

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

No wonder your signallin is not reaching the final client.
I didnt't suggest to throw OpenSips. NAT handling is delicate woth proxies.

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

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...
Forwarding registrations is fine, no need to authenticate them on K port 8080. Perhaps providing the relevant part of your config along with a ngrep SIP trace on K port 8080 will help to give you the right directions to get it work.

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?

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.

Hi Robert,
There can't be any simpler start then using the configurations(kamailio.cfg file) mentioned in this blog-post by Daniel.
http://kb.asipto.com/asterisk:realtime:kamailio-3.1.x-asterisk-1.6.2-astdb
You can see a *route[REGFWD]* and in that route you can relay the REGISTRATIONS to your desired SIP-Server!!
This is by far the easiest and simplest start I've found without any headache of going deeper into the SIP packets and techniques.
See this is the concerned route.
# Forward REGISTER to *YOUR_SIP_REGISTRAR_SERVER* route[REGFWD] { if(!is_method("REGISTER")) { return; } $var(rip) = $sel(cfg_get.asterisk.bindip); #CHANGE THE asterisk.bindip/asterisk.bindport on the top $uac_req(method)="REGISTER"; $uac_req(ruri)="sip:" + $var(rip) + ":" + $sel(cfg_get.asterisk.bindport); $uac_req(furi)="sip:" + $au + "@" + $var(rip); $uac_req(turi)="sip:" + $au + "@" + $var(rip); $uac_req(hdrs)="Contact: <sip:" + $au + "@" + $sel(cfg_get.kamailio.bindip) + ":" + $sel(cfg_get.kamailio.bindport) + ">\r\n"; # Change Kamailio.bindip/port as well. if($sel(contact.expires) != $null) $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $sel(contact.expires) + "\r\n"; else $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $hdr(Expires) + "\r\n"; uac_req_send();}#!endif
Make sure you do DB tables and Variables adjustments accordingly.

I don;t think there is any difference in configuration working for asterisk and not for anything esle..REGFWD is just a piece of code which can forward registration to any IP:PORT where SIP is enabled and working. If you carefully deploy that configurations keeping in mind only your software (replace-all asterisk with portaone) won't that help !! Like I said before its a starting point, you may need to put one or two more things/modules/functions like Path() to have this thing working for you.

Hi Robert,
There can't be any simpler start then using the configurations(kamailio.cfg file) mentioned in this blog-post by Daniel.
http://kb.asipto.com/asterisk:realtime:kamailio-3.1.x-asterisk-1.6.2-astdb
You can see a *route[REGFWD]* and in that route you can relay the REGISTRATIONS to your desired SIP-Server!!
This is by far the easiest and simplest start I've found without any headache of going deeper into the SIP packets and techniques.
See this is the concerned route.
# Forward REGISTER to *YOUR_SIP_REGISTRAR_SERVER* route[REGFWD] { if(!is_method("REGISTER")) { return; } $var(rip) = $sel(cfg_get.asterisk.bindip); #CHANGE THE asterisk.bindip/asterisk.bindport on the top $uac_req(method)="REGISTER"; $uac_req(ruri)="sip:" + $var(rip) + ":" + $sel(cfg_get.asterisk.bindport); $uac_req(furi)="sip:" + $au + "@" + $var(rip); $uac_req(turi)="sip:" + $au + "@" + $var(rip); $uac_req(hdrs)="Contact: <sip:" + $au + "@" + $sel(cfg_get.kamailio.bindip) + ":" + $sel(cfg_get.kamailio.bindport) + ">\r\n"; # Change Kamailio.bindip/port as well. if($sel(contact.expires) != $null) $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $sel(contact.expires) + "\r\n"; else $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $hdr(Expires) + "\r\n"; uac_req_send();}#!endif
Make sure you do DB tables and Variables adjustments accordingly.

I've tried all combinations of rewritehostport / t_replicate etc…
perhaps t_relay_to(...) is enough, depending on what the r-uri address contain (should be registrar server address, if K on port 8080 is used as outbound proxy).
You have to use path module and the sip proxy on 5060 has to understand the path headers (it is not clear that proxy on 5060 is Kamailio, if it is, then it support path).
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…
Forwarding registrations is fine, no need to authenticate them on K port 8080. Perhaps providing the relevant part of your config along with a ngrep SIP trace on K port 8080 will help to give you the right directions to get it work.
Cheers, Daniel
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.

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?

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.

This setup is possible with Kamailio, Opensips, whatever.
First, the problem is not that you receive the message an port 8080. Even if you receive on 5060 and forward the request you will have problems.
This is a typical load-balancer/outboundproxy setup and there is no common solution for proper routing.
version 1: use the "Path" extension, if your "VoIP plattform" supports it.
version 2: depending on if the "voip plattform" does NAT traversal or not, you may have to rewrite the contact header when forwarding requests to the VoIP plattform, and in the other direction.
Thus, use ngrep/wireshark to analyse the message flow. Take a look at the IP addresses in Route/Contact and R-URI. Then fix it where it is wrong.
