The only remote meetings that work are ones where everybody is remote. Even if you are sitting next to someone in the same meeting, your both have your headphones on so that you only hear each other via the call. As soon as there is a room there is a struggle in my experience: it is too easy talk to the people in the room.

There is on type of in room meeting that works: the all employee meeting. The agenda is preset (first Joe will talk about goals, then Carla will go over financials, then Fred will update us on United way...).
