This is great for a handful of devices but I deploy and administrate hundreds of devices at my school. As much as I would love to, there’s no way I could sell this without a really robust way of managing device policies & software deployment. I understand RHEL has something like that but that it isn’t quite up to the same standard as the Microsoft admin ecosystem just yet.

I had multiple fan failures which brought down my system, so instead I picked up one of these heatsink cases and it’s been running mostly uninterrupted for years.

It’s a GPO 706, which is a classic British bakelite phone from the '60s. I have it hooked up to a SIP trunk through an OBi 100. Right now it can receive calls but not make them because I haven’t gotten around to sorting out a pulse-to-tone dialing converter yet.
