- jmp.chat phone number, shared between spouses as a “family number” either of us can answer at home or away from phone.
- Cell2Jack device that converts bluetooth phone call into landline phone
- Cortelco 2500 telephone
Video with sound here. Video was taken of Android phone Cheogram app, but I will instead use this setup with Raspberry Pi 4 + Waydroid/Lineage OS and Cheogram app in the coming days.
Yes, you can answer and dial out from the telephone instead of device for integrated phone apps like Cheogram. For Signal, I have to tap answer on device but can pick up telephone to continue the audio call.
Interesting! I’m sure there is some way to get it working natively on Linux and headless, but a cursory web search brought up nothing. I did just buy a Cell2Jack and a 1979 ITT Tel Touch phone to try this out haha.
Let me know how it goes, or if you get more creative. I wish I used the XMPP side more, but people I know use Signal or just text.
I hear ya. I’ve gone with Matrix to interface with everything else other than call/text, and it works well enough.
