That's not a bad idea!

I don't think a phone line adapter will be as easy as connecting wires from a RJ11 connector to audio plugs. Normal POTS lines use full duplexing to transfer audio in both directions with only two wires. You would need external hardware to separate these signals. I cant think of any way you could connect this type of line to your dap to do it in software. External hardware could be built from scratch, OR you could take apart an old corded phone, solder some wires to ground, the speaker, the mic, and the ringer and connect them to your dap like this:

GND -> DAP Gnd (Any one of the audio or remote grounds should work because ground is shared throughout the dap)
Mic -> DAP Audio Out
Spk -> DAP Audio In
Ring -> Resistor -> One of the remote jack's pins. I'm sure one of them, probably STOP, uses a dedicated on/off pin which can be watched by the software for rings.

That's my theory anyways.. :)
