I think it would beneficial to have a button that would show the rest of the participants that you have a question. This is helpful when in a presentation and the person with the question does not interrupt the presenter/speaker who has the floor. The indicator could be anything from a colored border around the video feed to an icon.
We currently get around by stopping every so often and ask each endpoint if they have a question, which is time consuming and not as professional as it could be.
Hello Jay, there is documents on video conferencing etiquette which is very beneficial for new users. This helps with folks talking over each other in meeting. Please contact me if you can not find any information on video conferencing etiquette.
Hope this helps,
