What is a Gatekeeper?What is a Gatekeeper?
A gatekeeper as defined by the ITU-T H.323 standardsis an optional device that provides access andbandwidth usage controls for H.323 devices on an IPnetwork.
May also provide address lookup and translation,conference accounting, and site/conference statusinformation.
It is the key element in the network that allowsendpoints to find other endpoints, gateways, and to
join multipoint conferences

Unit Operation - Conference ModesUnit Operation - Conference Modes
VOICE SWITCH All audio from all participants is mixed within the MCU and distributed. The loudest audio stream is selected and video from this participant is broadcast to all other participants.
FIXED BROADCAST
Video from a selected participant is broadcast to all other participants regardless of audio (audio continues to be mixed and distributed). This feature is available only through the Web management interface.
CONTINUOUS PRESENCE
Video from the four loudest sites is sent simultaneously to every terminal in the conference (in QCIF format). Each terminal combines the four signals into a single, quadranted display. Audio continues to be mixed from ALL sites and distributed back to ALL sites.
