An IP phone can be configured to work with RingCentral Meetings Rooms according to this link.

But no so such option appears to be available for those of us who have chosen (or forced) to use RingCentral Video. So now I have to have a Poly Studio X50 and a TC8 Controller for Video Conference. And then a Poly Trio 8800 in the same room for if we want to have a conference call using Audio.
