Subscriber side interface

• little retro handsets: box with crank, princess phone, trim phone..?
• analog interface (fxo)- bring your own real pots phone. (Some way to avoid high voltage ?)
• trrs jack - use an iPhone headset. Hold down the headset switch to dial.

Almost bought some old handsets. Going to try to make a carbon mic based wall mount box (fixed mic; speaker on a cord )

looks like you can still get new carbon transmitters
