Get a good A/V setup people, you have the technical ability and it's one of your main job interfaces. At the very least use a wired headphone setup and microphone so we don't play walkie talkie games as echo cancellation mutes one of us dynamically and your bluetooth headset adds 100ms random delays and a lower bit rate of audio. Also do ethernet to remove the delays and packet drops from wifi.
The fact of the matter is that most people (myself included) are able to read visual cues from others and adapt their message accordingly. Actual communication (which entails understanding) is just easier this way.
Some managers where I work tried to pressure people to have their cameras on. It was later implied this was based on personal assumptions about what the "big boss" preferred.
But then some people ignored it, and someone else said "wait, they can't make us, if they push it the union will back us up".
