  Love seeing old tech brought back to life like this. The tactile experience of dialing is just something else.

  Slightly off topic but you can also use a SLIC module to talk to old phones:

    This project uses the same AG1171 SLIC module; it's just not enough by itself and still requires a microcontroller (or at least non trivial logic) even before you get to processing the audio streams.
