Cool! I'm relatively young, so the only interaction I've ever had with a rotary phone was my dad finding one in a box at my grandparents' house. Still, this seems like fun. Cool that you can communicate with the cell modem directly.

Very cool.

My only nit is the local/nonlocal/alt switch is unnecessary. Local & nonlocal numbers have a different number of digits. Checkdown logic can determine which it is. The phone book certainly has less than 7 digits of pages, and less than 7 digits of contacts per page. The only issue is determining if a short number is for a contact or a contact page. That can be dealt with by pressing a different button than the call button if it's a page navigation.

I still have a rotary landline (well, VOIP, using a Grandstream ATA).

It is fun! But I hate people with a lot of 8's, 9's, and 0's in their numbers. They take forever to dial :)

Yes, I would have expected to replicate the standard user interface. That's what we did, here.[1] (at 00:08). That antique phone (actually a 1970s replica) produced a dial tone if lifted, and then you could dial calls. It's running over cellular, via a commercial box that interfaces landline phones to Bluetooth, comprehends dial pulses, and can generate ring voltage.

In some areas even local calls require an area code. There was a change not too long ago that increased the number of areas like that. https://www.usatoday.com/story/news/nation/2021/10/19/area-c...

I love it when people say "Oh, I'm not a programmer" and then continue showing the stuff they've built (and fully programmed) that is a way beyond in complexity than what most of us professional programmers get to work on, like ever... :)
