A red box is a phreaking device that generates tones to simulate inserting coins in pay phones, thus fooling the system into completing free calls. In the United States, a nickel is represented by one tone, a dime by two, and a quarter by a set of 5 tones. Any device capable of playing back recorded sounds can potentially be used as a red box. Commonly used devices include modified Radio Shack tone dialers, personal MP3 players, and audio-recording greeting cards.
Famous quotes containing the words red and/or box:
“The air is precious to the red man, for all things share the same breath—the beast, the tree, the man, they all share the same breath. The white man does not seem to notice the air he breathes. Like a man dying for many days, he is numb to the stench.”
—Attributed to Seattle (c. 1784–1866)
“A Cherokee is too smart to put anything in the contribution box of a race that’s robbed him of his birthright.”
—Howard Estabrook (1884–1978)
