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,

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
