Hand up with only one audio at once in large meetings

Hi! I’m discovering this app, I just looking for audio meeting system with 100 users and only 1 speaker at once. We are using actually paltalk.com it has this mechanism but fails in other features we need.

¿Has Jami includes this feature of 1 speaker at time? Because many users don’t know how to mute their mic, or some are not aware of that and would interrupt in a room with so many people.

It could be a very useful feature that i can’t find in any other system of video or audio conference.

In paltalk there is hand up button and a order list of hands up, but only one person can “take” the microphone and speak. Others must wait. This is a great system of turn or order in interventions.
