Video Clustering
.. A maximum of 15 conference participants can be supported by a single
MCU.
.. Two or more MCUs can be cascaded to support larger conferences.
.. Conference participants are unaware of the cascaded nature of the
conference.
.. Only a single voice/video data stream exists between cascaded MCUs.
.. Voice/video traffic can be localized by correctly dispersing MCUs across
a network.
.. The number of MCUs that can be cascaded together depends on
available bandwidth.
.. To invite a MCU to join a conference from a terminal, dial the host
conference password, the invite code **, followed by the conference
password of the invited MCU.
