I don't know if the elevator phones dial out or not. If they can be connected to a POTS line, like the Otis man said they can, then they would have to generate tones or pulses, I imgagine. It's good to know about the standalone ringdown circuit. I may need one. Does anyone on this board sell them? Please let me know.
