You need a telephone ring generator which generated the ring
voltage (around 20Hz 90V AC) to the telephone connected to it
when rign key is pressed. For commercial devices the possibilities
are telephone line simulator or theatrical telephone ring generator.

If you know electronics well to build somehing like this, then check
