Back to back meetings: next meeting attendees being able to join current meeting running over

[shaunawu]

Most of my days I am booked in back to back meetings on the half hour. If a meeting is running over, my next meetings participants are able to join. How do I disable that? I've enabled the waiting room setting, but that is not doing the trick. I want to be able to stop the next meeting attendees from joining a call that is running over.
