Sorry that I misread your post about changing the tone of the intercom, I somehow thought you were talking about the ring tones so two people close together could hear if it was their phone or the other phone that was ringing.
Maybe I am missing something, but if you set doorphone RINGING, how would that come across as a voice annouce to the page group?
If you set the door phone to ring a phantom, you would have a phantom owner and put the phantom button on each phone and set it to ring.
Now if I've screwed up anything this time, let me know and I will start drinking Becks before I read the question.
