Multipoint videoconferencing is largely very similar to point to point (P2P) videoconference. What differentiates the two is that there can be more than two participants in different locations involved in a multipoint system, meaning that multiple people can be displayed on screen instead of just one. To initiate a multipoint videoconference the multipoint control unit (MCU) either makes or receives calls from participants who dial the network ID of the multipoint control unit. Due to its cost and complex nature, multipoint videoconferencing systems are most commonly used in large corporations to conduct large business meetings with multiple parties.
