The Tucker Telephone is a torture device that uses the magneto generator from an old crank telephone to shock prisoners. The device was invented by a trustee acting as the "resident physician" at Tucker State Prison Farm in Arkansas, in the 1960s.At the "Tucker Hospital", an inmate was strapped down and electrodes attached to toes and genitals. When the crank was turned, a charge was shot through the body. “Long-distance calls” referred to several such charges, used until just before the point of losing consciousness. Effects sometimes included permanent organ damage and insanity. It was used until 1968.
The Tucker Telephone is also sometimes referred to as Radio Moscow. There are reports from American Vietnam war veterans that field phones were occasionally converted into Tucker telephones and used to torture Viet Cong prisoners. They're also used in sadomasochistic sex. (info from Wikipedia and Urban Dictionary)
