I doubt that will work quite like you are thinking. There is more to an

I don't think there is such a thing as a cross over phone line.
A "Phone Line Simulator" is a small box that permits interconnecting two
POTs. The one that I had/have(if I find it), also can create a ring

If you can find a Type L handset, it will fit acoustic couplers, but is a
