How would you interface a stamp to a cellphone in such as way that it the stamp can automatically answer the phone and then be able to register individual button presses, IE be able to tell when someone presses the number 3, as opposed to the number 5.

The answering part would probably be easy, i don't know how good it would be at registering keypresses, It would have to be some type of tone analysis
If you want to scrap the phone(IE, not make it usable for a human) just unsolder the answer call button and solder a transistor to it, then you could answer the phone.
If you could supply the forum w/ make and model that would help
