[Users] multiple aliases

[Mike Williams]

Is it possible to use aliases to route to multiple sip uri's?I would like to 
have one user resolve to say, three different users from the database. Also, 
I assume I can alias a local sip address to a user in another domain /  at 
another server? 

I want to have a virtual number that rings three seperate phones when called, 
regardless of whether they are sip or pstn. Ideally, I would be able to do 
this with aliases. Thanks for any help.
