Locking and Unlocking a Conference
You can lock or unlock On Going Conferences and thus control access of
undefined dial-in participants to these conferences. The Lock/Unlock option
is dynamic and can be applied any time before or during the conference. This
feature is used to:
• Limit the number of undefined dial-in participants connecting to the
conference in order to save resources.
• Prevent other participants from connecting to the conference once all the
required participants have already been connected.
