[SR-Users] Understanding alias_db correctly.

[Henrik Aagaard Sørensen]

Can someone help me by explaining what the alias_db exactly does:
http://www.kamailio.org/docs/modules/stable/modules_k/alias_db.html

As I've understood it, I can add several aliases to my subscribers, for example:
100 at my-domain.com can have the alias 600 at my-domain.com
and therefore a client can login with the username 600 at my-domain.com,
but really have the preferences of 100 at my-domain.com as that is the
real subscriber.

But it doesn't seems to work.
