Slightly simpler, you can pick up a telephone recording box
I had a cheap one that hooked into the handset, but I believe the deluxe

The hardware shouldn't be difficult at all, I'd like to see how the

I was once told that you could record a 14.4k data stream, and play it
back into a modem to demodulate both sides, but I can't imagine how it
would be done.

ring
voltage from frying my box.
