For inbound calls it is rather simple - just use aliases to map the DIDs 
over the username.
The problem is for outbound calls - the issue is how the user may choose 
the outbound DID. here you can do several tricks:
       1) use RPID to advertise the selected DID - user selects the 
outgoing DID via an interface on the proxy
       2) user change the the CPE cfg to use a specific DID in FROM hdr, 
but maintaining constant the auth username to be able to do auth.
