this case, Asterisk would have to :<BR>- fake original caller-name and
set it to "call for Alice", <BR>- replace original caller-id with Alice
extension (eg 4111 instead of +44 812 41 54 66)<BR>so that
hardphone gets everything it needs to :<BR>- recognize from
caller-id that the calls comes from Alice (though it's a call FOR Alice) <BR>-
and then uses Alice ringing tone instead of Bob's tone.<BR><BR>Is this roughly
correct ?<BR><BR>How many phones behaves like this ?<BR>As you said, it would
be sad to loose SIP portability.<BR><BR>It would be nice to use SIP protocol
