One of the great features on the MCU is the ability to secure conferences from unwanted participants. The MCU provides two methods to do this; locking the conference or creating a pin code for the conference.
Locking the conference disables anyone from joining a conference who has not been invited as a pre-configured participant. To add preconfigured participants go to the Conferences tab and create a new conference. The “ADD Participants” tab will be in the upper right corner of the screen. Participants can still be invited after the conference has been locked. Adding participant after a conference has began can be performed in a similar fashion. From the Conferences tab select your active conference. Go to the Configuration tab of that conference and add your pre-configured participants. The process of allowing only preconfigured participants to join a conference is know as Whitelistening.
Anther option to secure a conference is the use of a pin. If configured, there could be two different pins. One for the normal user called a “guest”, and the other for a user with more privileges within the conference called “chairperson”. If the conference has no chairperson, then the meeting will act like a normal conference after the participants enter the pin. If there is a chairperson, only when the “chairperson” enters the conference will the video and audio for the conference initiate for the other participants. If the guest participants enter the conference prior to the chairperson entering all they will see is a blank screen with the text “waiting for conference chairperson”. There can be more than one chairperson for a meeting. The chair can also add, reset or clear the “guest” PIN. A PIN can also be applied separately to the participants who are “chairpersons”.
There is a lot of flexibility the MCU offers to settings this up. All of these options can be applied or none of them. It’s up to your organization to decide what will satisfy your needs.
