We built an MTR console on a mini pc in our lab to test the rooms. It is connected to a monitor and camera too. None of the devices are in the approved device list of Microsoft but it works. We are able to place video conference calls with it.
My question is that how come it does show as an MTR device under the admin.teams portal. We followed the official Microsoft instructions to create the rooms device and user account for it. So I am not sure why we cannot see it. What are we missing here?
