To be slightly more accurate, I wrote “I continued to mess around with a mobile broadband modem, and got it working! With a caveat… it only works when plugged into wall power.”, “it” referring to the mobile broadband modem. Only the usb connected broadband modem requires “wall” power to function, technically it only requires 25W consistently to be provided to the pi5, or some other direct power.

The device is a great little handheld that functions as a full linux computer that works completely on battery power! I bet your landline can’t do that!

But, that’s besides the point! Give the SPIRIT phone project a look on github! https://github.com/SPIRIT-org/SPIRIT

Thanks for the suggestion, I mirrored the repo here: https://codeberg.org/muhammadmanwar/cheaphone

I may end up switching entirely to code berg, but I’ll see how bothersome it is to push changes to both before I fully migrate. Thanks again!
