Yes; there are several different privacy features. Each call has a unique Participant Access Code for entry. Participant Access Codes are uniquely assigned for all services, with the option to choose your own for our Web-Scheduled services. During the conference call, a short tone identifies users' entry and exit. The conference organizer can (1) find out the number of people on the call by pressing star-pound “*#” on the touch-tone keypad; (2) lock the conference (to prevent additional parties from entering) by pressing "*5" on the touch-tone keypad. For additional commands, see Hotkeys.
