  • the first control device and the second control device are configured to advertise a same external network address to videoconferencing terminals on at least one external network;

    each of the first control device and the second control device is configured to receive a videoconferencing session initiation request from a respective videoconferencing terminal on the at least one external network and to designate a respective processing device of the plurality of processing devices to receive data from the respective videoconferencing terminal during a respective videoconferencing session;

    each processing device of the plurality of processing devices is configured to;

    receive data packets for a videoconferencing session;

    process the data packets; and

    send the processed data packets across the packet-based transport network to other processing devices of the plurality of processing devices participating in the same videoconferencing session; and

    the videoconferencing system is configured so that the first control device and the second control device do not receive any audio-visual data packets, but receive control data relating to videoconferencing session initiation and management, while a designated processing device of the plurality of processing devices receives all audio-visual data packets sent by a videoconferencing terminal, within a particular videoconferencing session.
