found that wire long ago
Dave,
I ran a service station nights and the pay phone was inside the office. Somebody would camp on that thing at closing time and I couldn't close and go play pool. Fortunately the phone line ran through the supply room. A little checking to find the hot wire which could indeed give quite a tingle, a toggle switch, and I closed when I wanted to! Ma Bell never did find my little modification.

A cool thing about those rotary phones was their bell. It takes a bit of juice to get that striker ringing the bell. Every phone line, when ringing, drives the line with enough AC voltage to give one quite a shock if you happen to be working on the line at the time :yikes:
If you hung enough phones off one line, and that line was quite long, your bells would hardly ring if at all. I knew a man who mod'd his rotary, he cut the striker off with sidecutters so people wouldn't bother him ... he could dial out but heard no incoming calls ... his telecomm/datacomm company had to send a courier by his house letting him know when board meetings were scheduled.
These days electronic phones take a way less powerful signal to get them ringing (bleeping, boinging, or however you've programmed them), but I'll bet you still get a big shock from the phone line ... thanks to those long-gone bells.
