Could you elaborate ? I know some hardphone (eg Thomson ST2030) can set ring-tone according Caller's presence inside phone's directory. In this case, Asterisk would have to : - fake original caller-name and set it to "call for Alice", - replace original caller-id with Alice extension (eg 4111 instead of +44 812 41 54 66) so that hardphone gets everything it needs to : - recognize from caller-id that the calls comes from Alice (though it's a call FOR Alice) - and then uses Alice ringing tone instead of Bob's tone. Is this roughly correct ? How many phones behaves like this ? As you said, it would be sad to loose SIP portability. It would be nice to use SIP protocol to drive such behaviour.
