Shark biting an undersea cable

You don’t say what mode you have the enclosure set to. If you have it set to software control mode, only Windows is supported and it’s going to do some weird proprietary stuff that needs the qnap software.

This isn’t a Valve project

I have an N150 proxmox setup as well. I had to enable iommu in the kernel to get pci-e pass through working (intel_iommu=on).

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.
