Code Black - Express Teleconferencing High Security Conference Calls   Background   Some conference calls are of such a confidential nature that the host has to be 100% confident that only select people are able to attend the conference call and that what is said does not go beyond this select group.   Solution   Express Teleconferencing has introduced the Code Black Conference Call.   The organiser provides the Express Conferencing Consultants with the following details:   Time and date of the Code Black Conference Call Host Access Code Host’s name and contact number (plus secondary number if available) Guest’s name and contact number (plus secondary number if available)   The Express Conferencing Consultant will call all the participants, connect them into the conference call and conduct a role call. The Host will be advised that the conference call is ready to be locked by pressing *7 on their telephone key pad.   Once the Lock feature is pressed an announcement is played into the conference stating “The conference is now locked’ ensuring that no one is able to enter the conference call (including the operator).   Should the Host require assistance from the operator, the conference can be unlocked by pressing *7 again and a message stating “The conference is now unlocked” will be played and the operator can be signalled by pressing *0 on the telephone keypad.   For further information on the Code Black High Security Conference Call please call Express Teleconferencing on 1800 266 337.
