Hello,

For non-commercial support please address our sr-users list (added to CC).

Please look at the uac module, there a function uac_auth() for this particular scenario with example cfg.

Cheers,

Henning

Subject: kamailio Trunk authentication

Respected Sir,

I am new to kamailio so not very familiar with config PV’s and transformations etc.

I have successfully authenticated the Twilio SIP phone via ACL.

But I also willing to authenticate the Twilio SIP via username and password.

For doing this I plan to modify the “proxy-authentication” header as blow:

if (is_present_hf("Proxy-Authorization")) {

            $nonc=$sel(proxy-authorization.nonce);// not working

            $has="kamailio:$ar:SdE-----------ADVpa";

            $ha1=$(has{s.md5});

            hat="$aa:$adu";

            $ha2=$(hat{s.md5});

            $resp="$HA1:$nonc:$HA2";

            append_hf('Proxy-Authorization: Digest username="kamailio", realm="$ar", nonce="$nonc", uri="sip:+1650ZZZZZZ@XX.YY.7.195", response="$(resp{s.md5})"');

}

            remove_hf("Proxy-Authorization");// remove original header

When I save the config file and restart kamailio, it does not start, may be due to some error in code.

Can you please help in authentication of a SIP trunk using user/passowrd.

Thanks in advance
