Very nice job! Last month I also adapted a rotary phone but I replaced the insides with a Bluetooth chip (and some more). Now I can use it as a headset for my smartphone or laptop. While you had to learn about SIP and voltage converters I had to learn about Bluetooth and digital audio protocols. Looks like we both had fun ;)

Mine has a couple of irritations (not able to charge when off, voltage dropping below 5v after the battery loses a bit of power so the mic and speaker stop working, etc). Feel free to reach out if you have any questions!
