Re: Raspberry Pi in Rotary Phone
#2My child is old enough now to stay home alone during short errands. Since we don't have an old school land line it would be cool to take inspiration from a project like this and build her a "red line" device that gives her immediate access to reach me without breaking down and buying her a cell phone yet.
But what would I hack together for the software side of that?

I'd skip the projects and just buy one of the numerous phones that target this market. They make watches, dumb phones, and smart phones, that are locked down and only allow phoning/texting specific people.
The other option would be to get a real copper phone line.
My reasoning is that a real emergency may include a power outage. Relying on some cool hack isn't going to be helpful when your child is trying to reach out to you when there is no power at home.

If only Whatsapp/Signal/Telegram has open APIs to allow voice calls...
But I guess using VoIP software it's not a new idea: https://github.com/hnesland/aselektriskbureau
It would be neat to enable dialing, e.g. "1" for Mom, "2" for Dad...

If you’re in the Apple ecosystem the homepods can intercom.

The software could be pretty simple. Hook a button up to GPIO, write a bash wrapper around one of the command line VoIP clients, write a little program to call the script when the button gets pressed, autorun that one on boot.

#8I've been meaning to build a similar project for my SO. I want is to be able to connect the rotary phone via bluetooth for calls (only calls) and dialing if possible. Has anyone worked with anything similar that can provide some pointers?
I'm guessing the dialer part should be "simple" as I could probably connect an Arduino as if it were a keyboard but can't find much on the audio part.

If you are within short range radio coverage, why not walkie talkies?
Check PMR446 (EU), FRS (US) and similar services.

You can buy an ATA (Analog Telephone Adapter) to convert old analog phones to VOIP, and then use it with whatever VOIP service you want. Just be sure that the adapter supports pulse dialing since you want to use it with a rotary phone (not all does).
