You mean you've added the users to the subscriber table?

You've enabled auth in the cfg given below, so this is the expected behaviour. 
Your UA should reply with the proper credentials, then the call should be 
established. Take a look to the log file of the kamailio, and do a sip trace 
(e.g. with ngrep -W byline port 5060) to get more information about the 
eventual problem.

Normally you only need to enable multi-domain support (there is no such a 
thing as multi-domain module) if you want to serve multiple domains where 
you've some overlapping the user sets, e.g.

- user1 at domain1
- user1 at domain2

In this case then you need to look also to the domain in order to differ 
between both.

Cheers,

Henning
