I’m currently using a Banana-PI R3 which meets those requirements. It only recently got release support for OpenWRT, but SinoVOIP seems to be actively working with them (which is confirmed with this announcement). There are still small issues (last I checked the boot loader method of cloning to nand is broken), but it’s been pretty solid for the last 5 or 6 months. I was coming from a late model AirPort Extreme but needed something with more configurability. My biggest with it issue is that the BPI is a fast computer with lots of RAM and storage (and SD and M2 expand ability), but OpenWRT is made for the tiniest embedded systems and everything from configuration to pre-built packages prioritize space over quality of life. Busybox is fine, but when I have as much power as a desktop computer from 10 years ago, it feels like an unnecessary inconvenience. Or as I just went through, Ruby installs the Ruby interpreter and nothing else, each module in the standard library is a separate package and someone went through the work of configuring the dependencies of each of them. Likewise, LUCI is great, but sometimes I just want to configure a thing, not have to find the LUCI configuration for the thing.
