phonetone Stop robot callers with a tone

Aparently there’s a U.S. Special Information Tone signal for a dead phone line, and robot callers (telemarketers, debt collectors, etc.) listen for it, then remove the “dead lines” from their lists. Record it at the beginning of your answering machine messages to make (some) robots stop calling you! [via] Link.
