You would have to make a circuit to convert ring voltage to operate a relay

You set up a single line extension to follow the line ring and you can probably figure out how to use a WTB or just about any external ring control box. https://www.sandman.com/pdf/page40.pdf Carl

thanks for the advice. i will get one of those relays. seems easier to do that as an extension than to find the place on the tda50 board where it has a relay?
