Webex Room Series: a lot of potential, but still needs some work with documentation and codec efficiency

We use the Room Series for bi-directional remote classes and webconferencing. We currently have a single 4K camera above the two TVs connected to the Room Series, but this will be upgraded to two cameras and 4 TV in the near future. The system works very well currently in its limited use case but I suspect that for true remote classroom experience, the single camera system will be found inadequate. The reason for this is because it is incapable of display the instructor, the classroom with students and the annotation board at the same time. We have had some compression issues in the past with video streams when the connection becomes slower but this is to be expected. Finally, when we use this system as a SIP to connect to the zoom service, while it works really well, the dial interface incorporated with the Room Series is arcane and difficult to master. For example, sometimes we need to be able to change the view to gallery instead of active speaker. To get this to work, we have to go back to the dial menu and punch in a bunch of options to make it work. This is very cumbersome.
