Beige boxes can be usually constructed with easily available materials, such as a simple corded telephone, a soldering iron, and a pair of alligator clips. Usually a switch is added in order to turn the microphone off (mute), so as not to introduce excess noise into the line. Although it is generally not illegal to possess or construct a beige box, it is illegal to use them to make unauthorized use of a phone line, because this violates wiretapping laws and the user is tampering with telephone company equipment. Green and red wire are the only wires that need connection in order to both talk and listen. Usually this method is done by stripping a portion of the land line and attaching alligator clips linked to a corded phone. Instructions for constructing a beige box can be found in many places on the internet, as well as instructions on to make other phreaking boxes.
Alternative beige boxes can also be built by connecting alligator clips to an RJ11 jack. This method does not require modification of a telephone -- any kind of telephone can be used. The original Beige Box was created by The Exterminator and The Terminal Man in 1985. The term "Beige Boxing" has become the generic term for illegally connecting to a phone line.
