Okay, I, like Generic_Phreak, am planning to break the mute function of a Millenium payfone. And I need some advice. The text files at hackcanada and elsewhere describe the mute wire as "plain copper in clear insulation". The contents of the armoured cable of my payfine are these:
One thick silver wire, threaded like rope, inside clear blue insulation.
One thick black cord, inside which is four wires: redish, green, yellowish, and copper inside blackish clear insulation.
Soooo. Where's the mute wire? We can rule out the red and green wires, obviously. But are the yellow and black wires analogous to the ones in an RJ11 jack, or not? And what is the huge silver/blue one for?
Any thoughts are appreciated.
