I think he wants to read the buttons directly without DTMF?
Edit: to clarify, yes it is a land line, and hopefully a touch tone.

That will be much easier than a mobile phone.One more question for clarification: Does the phone need to continue working as a landline phone in addition to playing sounds? If not you could tap into the matrix keyboard and use the Keypad library to translate key presses directly to characters.
