- 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.
Oh ok I get it now, so basically the fixed phone is used as a controller for your regular phone. That makes more sense actually, I tought when reading your post that is was some kind of phone that stays in a cabinet near by. But if its basically a bluetooth speaker/microphone that you can decide to use to pick up the phone instead of using your smartphone, then I love the idea!!
