Some useful information would be lost here though: in the OP's proposed 
configuration, when the UA receives an INVITE, the will have already 
done the RFC3841 matching process, and evidence of that process will 
appear in the request sent to the UA.

With a single Contact URI registered, the UA would have to do the caller 
preferences matching itself to determine which of its internal 
applications to deliver the request to.
