[SR-Users] UAC Module

[Ali Jibran]

Perfect. Yeah got the working. 

Just one last issue. I don’t think this is rewriting the header. When I log the header again after the changes it still shows me the old values.

t_on_failure("F_VOIP") to be used before t_relay();

That will arm the call to go to F_VOIP on failure responses.

        t_relay();

        

}

 

 

failure_route[F_VOIP] {

        uac_auth();

        xlog("L_INFO","ALERT: IN FAIL");

   }

 

 

I tried this but it never makes it to the failure branch. Im a newbie to kamailio and still working around the scripting. Can you please help me out here to where I am making the mistake?

Hi Jibran,

 

Here is an old thread as reference:


http://lists.sip-router.org/pipermail/sr-users/2013-August/079336.html

 

I wouldn't want to do the whole handshake of INVITE,PROXY-AUTH,INVITE with username/password on a Provider for huge number of calls..imagine sending thousands of call to that provider and for each call going through the trouble of exchanging authentication. 

Thats why its usually recommended to go with IP-Authentication only. Send INVITE and Provider says Lets do this call,simple and easy.

 

>From the configuration perspective this is my idea of still using UAC.

 

- Call coming from FS on kamailio

- Rewrite the from-uri  (so the provider receives calls from the registered username)

- modify the to-domain part to contain the IP address of the provider

- set the $du to ip of the provider, and t_relay() the call.

- Most likely the Provider would say Proxy-Auth required..that can be caught in failure_route[]

- There you can call the uac_auth() function to have username.password attached to the response of above. http://kamailio.org/docs/modules/4.3.x/modules/uac.html#uac.f.uac_auth()

- once this function is successful send the INVITE again to the provider.

 

Last three steps can be the following snippet of code(reference from here <http://opensips.org/pipermail/users/2010-August/013947.html> ):

 

failure_route[2] {
     if (t_check_status("40[17]")) {
        xlog("got challenged \n");
        if (uac_auth()) {
            xlog("auth was succesful \n");
            t_relay("udp:ip_addr:5060"); //provider's IP_ADDR
        }
}

 

 

I hope you get IP Auth from the provider, and find the reply useful.

 

Regards,

Hi all.
I have this setup.
Trunk--->Kamailio---->FreeSWITCH

I have a trunk from a sip provided and registered successfully with the UAC module. Incoming is working fine. I need to make out going through kamailio too.

I have it in the dialplan to forward the invite to kamailio from FreeSWITCH. I can see it the logs that it reaches kamailio. Now how do I make the call via the trunk?

Basically this is what I'm trying to workout
FS---->kamailio---->trunk.


Any help will be much appreciated. Thanks.
AJ
