MeetingPlace Express has a hardcoded setting called the "disconnect empty port" timer that
is non-configurable. This timer is set to 30 mins. This means that if nobody is in a
meeting for 30 mins, the system will end, even if the meeting was scheduled to end at a
later time.
However, please note that several similar timers are configurable as well. All of these timers can be found under "Meeting Configuration" within the Administration center.
