I don't think this makes sense.  You need to know the aliases when you 
are doing an INVITE, not when you are REGISTERING.   So for example if 
you call user 111 which is also an alias for 222, then SER needs to know 
that alias when an INVITE is heading for either 111 or 222, not when the 
user is registering.
