T. Kekatos: This summer, I had two relays connected to my phone line so that when one phone was lifted in one room (these were separate dwelling units...), the other would be disconnected, and vice versa. It worked satisfactorily, though there was the slightest buzzing noise in the background. But for the unfamiliar with less kludgy solutions, could you provide a schematic for your transistor plan?
