Seven things that make a meeting room work for hybrid calls
The remote seat is the hard one
A room passes or fails on the experience of the person who is not in it. Everything below is judged from that seat.
The checklist
A camera wide enough to see the whole table. A microphone that reaches the far end of it. A display the in-room people can see without turning away from the camera. Acoustic treatment on at least two surfaces. Lighting in front of faces rather than behind them. A whiteboard the camera can actually read. And a way to join the call that does not require a cable.
Book ten minutes early
Every hybrid meeting loses time at the start. Booking the room from ten minutes before the meeting is the cheapest fix available.
