This is every remote meeting in my experience, regardless of technology. The first 5-10 minutes or longer are spent getting everyone online, seeing and hearing each other, resolving echos and feedback, etc.
One of my best video conferencing purchases was a Jabra speaker/microphone that has a ring of LED's that tells me when it's muted. It's not always clear in a UI whether the mic is muted or not "The mute icon is bold white, does that mean it's muted or does that mean I need to click to mute?", but I can tell from the red LED's on my speaker, and it has a mute button on it so I always know how to mute.
