Easiest solution would be a simple Radio Shack 24 or 18 volt DC power supply on the tip and ring of the phones and a small 12 volt DC piezo buzzer on the spare pairs with a pushbutton to "ring" it.
The elegant solution is to use a Viking DLA-200B ringdown.

they both have ringers in them, the old bear gave me a solution a few years ago, I just lost it Chip
Well you could use ringers, but its not so easy a solution. You'd need a 90 VAC power supply and a way to detect ring trip to stop the ringing or feed it on the spare pairs), then a balanced 24 VDC feed (although you could get away with a ground sided one).
