If 1 click was for 0, how many clicks for 1?
I would imagine 2
Exactly. D+1 for every digit.

#52Are there any VOIP boxes that work with dial phones?
The Grandstream HT802 is the device I am using. It allows two analog phones (including dial phones) to connect to a VOIP provider. Each phone can have different servers.

I remember growing up our family got an extra phone we could use in the basement (I think it came with a magazine subscription oddly) . It had the keypad, but would just generate the pulses like a rotary phone. Very slow and felt wrong. I’m pretty sure this phone didn’t have the switch to go into “tone” dialing mode like our other phones which were only tone. it wasn't the famous "sports illustrated" sneaker phone wh…
I don't remember the sneaker phone, but I do remember the football phone: https://www.rollingstone.com/culture/culture-sports/the-funk...
I didn’t remember that one, pretty fun. I do remember the “nfl follies” game blooper vhs tape. Was pretty funny. I can’t imagine them doing another one.

#54A fun fact about pulse dial is that you can dial a digit d by quickly tapping the switch hook d times (zero is 10 taps). This is useful for dialing from a phone with the dial intentionally disabled or removed.
I've shared this story before, but you may find it amusing: Back in 1996, I was living in Almaden Valley (South San Jose) and we had underground utilities. We also lived on top of an underground stream. After a rainstorm, water got in and intermittently shorted out the phone line. It was clicking like crazy! I was on my cool new Motorola StarTAC talking with Pacific Bell to report the problem. Then I heard a loud kno…
This wouldn't have happened if the number was 0118 999 881 999 119 725 3.

#55Very 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 ;) https://blog.waleson.com/2024/10/bakelite-to-future-1950s-ro...
Wow, this is a project I've been kicking around for years! I have an old red rotary phone (a bit newer than yours) held aside just for it.
Definitely bookmarking your post

If you're comfortable designing PCBs I would definitely take that route and base it on the components I've used. 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!
