What is an MCU?
A Multipoint Control Unit (MCU), also known as a bridge, is a device that is used to bridge multiple video conferencing connections. Video conferencing systems can only make point-to-point calls on their own, or in other words, they can connect to one other video conferencing system at a time. MCU’s allow multiple video conferencing units to connect to one call. Some video systems have the option for an internal MCU otherwise a separate piece of hardware or a cloud based Virtual Meeting Room is necessary.
