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

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
