Hi! I have three old rotary dial phones, and I’d love to get them working as an internal phone system in my three-story house.

My idea is simple:

Dial 0 → basement phone rings

Dial 1 → middle floor phone rings

Dial 2 → attic phone rings

I’m not sure what the best way to achieve this would be, and I’m open to any kind of solution (vintage hardware, modern adaptations, or a mix of both).

Has anyone here built something similar or knows how this could be done? Any advice, recommended equipment, or pointers would be greatly appreciated.
