Conference Lock

At anytime during a conference call, the Host may lock the conference by touching #5. This feature can be used to increase the security on a conference, ensuring that no additional participants can enter a conference when it is locked. Once a conference is locked, any new participants who try to enter the conference will not be allowed to join, and will hear the following announcement: "I'm sorry, the host has locked the conference. You may want to try calling back later". If desired, the host can unlock the conference by touching #5 again. The Host can lock and unlock the conference as many times as desired during the conference.
