That is doable, but it can result in a bad experience for the caller.
The Dial() is likely to indicate progress to the caller, which means
that the caller will hear the familiar "dialing" tone (By the way, is
there a dictionary of the names for the various telecoms tunes?). Right
afterwards they will hear the busy tone, as if the callee rejected the
call.

It is best not to send a busy tone once you have indicated that the call
is on the way to being connected -- unless you're trying to get rid of a
telemarketer.
