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.

That’s right.

I’ve run a TR-004 for the last 5 years haven’t had any reliability issues so far. In hardware raid modes, drives are hot swappable but you can’t grow the array without wiping it. I’m JBOD mode you need to power off before swapping drives. The main problem I’ve had is their chipset is only partially supported by smartmontools due to proprietary crap so there is some strange behaviour there.
