I've been considering this idea for a while (I specifically need it for something :-))

The idea is simple...I want to record a 2-way data conversation over a phone line as I have a piece of hardware which communicates with its server and I want to know what it sends and receives. I can handle the "listener" section that goes on the wire between the device and the wall, but I am thinking about how easy it would be to decode the data from a *saved* WAV file. The WAV, I assume, would have 2-way traffic divided into two lines (left and right audio, perhaps, or maye stored in 2 WAV files, I dunno)

Basically, how simple do people think it would be to convert the tones to values (0-255 a byte at a time, I would assume, although 0 and 1...which would then be converted to 0-255...would work just as well)?

I'm sure there must be a way to do this...although I am sure there would be tons of complications :-)

(BTW, excuse my not replying if anyone answers...I'm off to work until about 8pm, about 8 hours after this is posted...I'll read the replies when I get back and make any replies I need to :-))
