Each authentication method in kamailio always gives some return values which are very useful to help understand and debug authentication failures. For example read return values of www_authenticate method here,

http://kamailio.org/docs/modules/4.2.x/modules/auth_db.html#auth_db.f.www_authenticate

All you need to do is check the $retcode or $rc immediately after calling the authentication method and check status using switch-case,

Thank you.

Hi,

I'm using kamailio 4.2 some of my clients are getting 401 unauthorized after a couple of days of usage without any problems, their usernames and passwords are still in the database server unchanged.
Any idea what's going on?
Thanks
Ahmed
