[Serusers] SER as fake SBC...

[Natambu Obleton]

For yawl out there. Here is a working copy.

 

http://www.natambu.com/sbc-rtpproxy.cfg

 

 

Setup the clients with a domain that points directly to the interface of
your softswitch, and put the ip address of the SER server into the 'proxy'
section of the configuration.

My softswitch doesn't support clients behind NAT, but to use the centrex
based features I need the clients to register directly with the softswitch.
So pretty much I need it to proxy for NAT translation.

I'm curious: Why do you want to simulate an SBC? (that is Session Border
Controller for those who don't know)
Topology hiding? Do you want to proxy everything as well?

If anyone is playing along with me.. I got registration to work. I replaced
"save" with "save_noreply". Now to get NAT working..

I understand that SER is not an SBC, but I can see how it could maybe do it.
So I started with hello-world.cfg from the onsip.org crowd and started
playing. So I rewrite the contact address to send the address and port of
the SER server and that works. I can make calls out, but when call come in
they get routed to SER and it fails because my UA is not in the location
database.

        if (uri!=myself) {

                if (method=="REGISTER") {

                        if (!subst('/Contact:  <mailto:sip:(.*)@(.*)>
<sip:(.*)@(.*)>/Contact:  <mailto:sip:\1 at 206.123.214.55:5060>
<sip:\1 at 206.123.214.55:5060>/ig')) {

                                log("******************************SUBST
FAILED ************************************\n");

                        };

                        # save("location");

                };

                if (!t_relay()) {

                        sl_reply_error();

                };

                break;

        };

 

 

When I have 'save("location")' in my configuration, Then I don't get
registered with my softswitch. So what does 'save("location")' do exactly?
Beside put an entry in my location database? Thanks. 

 

In my setup I am not using NAT at all. UA, SER, and my softswitch all have
public ip addresses.
