I'm looking at the same thing now, for AU busy tone.  If there's some 
work-in-progress that you wouldn't mind releasing, I'd be keen to have a 
look.

I think the problem with the current code (for us!) is the short length of
time over which it tests for busy.  Extending this might help prevent
voice-off.  It will be a balancing act though, as down here the ringing
indication is the same frequency tone (and I'd rather not have my outgoing
calls detected as busy when they are actually ringing).
