Press *31 to activate or deactivate the conference security code. The conference security code option requires all conference participants to enter the moderator-provided security code. When you activate the conference security code feature, you are prompted to enter the security code to be used for this conference. You will need to provide this security code to your participants so that they can enter the conference. Participants already in the conference will not need to enter the security code if this option is activated after the conference has started.
Pressing *31 in a conference that has the security code activated will deactivate this feature. Participants will not be prompted for the security code when joining the conference.
