Is there a way to see when the person I am calling is on another call?
If the person I am calling is on another call, rather than saying 'engaged' or 'busy', it just keeps ringing.
People have called me back saying they were on another call etc. so I know that they were in fact engaged.... Is there a way I can change it so that I can tell when the other person is engaged?
