Hi all,

I just try integrate Kamailio with external software and We want taht kamailio doesn't authenticate users. I want that the autehtication process would be done by external software. I want To receive a REGISTER for a user. Then I send a 407 and then when I receive all paramters for autehtincation(nonce, response, digestURI, etc, etc etc) send that data to external software and receive if data is correct, then sent 200 OK and save location in external software.

Bu t I can see any pseudovariable or enything else to obtain that dato to provide to external software. Anyone could think that this process could be done?

This is one of the reasons I built http_client - we fetch the data with http_client and feed it to the pvar-based authentication.

It’s tricky if you can’t use that since the 200 OK is special and needs to include all current contacts, not just the recently registred one.

So fetch username and pwd from external system or feed external system with all data to confirm.

If the location is saved in the external software, then the Contact header(s) for 200ok can be returned in the http response and added to the sip reply with append_to_reply(...).

If the location is also saved in kamailio, then it is save(...) that generates the 200ok, independent of authentication mechanism. So all works fine without need to fetch user/password to use them in kamailio.cfg.

For auth in external app - you can get the auth attributes from the Proxy-/Authorization header. You can send all that header to the external application -- for example, for REGISTER the var $hdr(Authorization) will give you those attributes.
