Mechanics of Conference Calling

All conference call participants are provided a phone number to use to dial into the conference call, as well as a bridge number. A few minutes before the conference call is scheduled to begin, the moderator dials the conference call number, keys in the bridge number, and then keys in the moderator's personal identification number (PIN). After the moderator opens the conference call, then the other participants can join in. Participants dial the conference call number, and then key in the bridge number. As long as the moderator has opened the conference call, then the participants immediately join the conference call. Other conference call participants hear a chime to let them know that another person has joined the conference call.
