If you picked it up, you heard nothing. If you called it, it rang. I was busy so I forewent my usual 'telephone repairman' role at the office. Then, I was sitting at the desk where this particular phone sat, jotting down some notes. I noticed a particularly noxious odor, and followed it to the phone in question. Strange, I said to myself. About to turn the phone over to take the cover off (this is a perfectly standard touch-tone desk telephone), I pulled on the cord to get some slack. It was hot. Very hot. I pulled the clip/plug out of the phone, and the two middle wires were glowing orange, the tiny plastic divider tooth between them was black and melted, and the whole thing smelled horribly. As I watched, the plug defiantly sent a little spark flying towards me. Needless to say, I unplugged the other end from the wall. Now, I have accidentally shorted phone lines across my body, even through my face when I didn't have wire clippers and was stripping a live wire with my teeth. It tingled, but certainly didn't hurt. Is there enough power in a phone line to melt plastic and make wires glow? This struck me as extremely odd. I plugged in another phone and cord and they worked perfectly, so I don't think something else was shorted across the phone line. Why did this happen? If it happens again, what if a fire starts? Could it be cheap phones/cords?
