H.323 architecture
An H.323 network consists of terminals, voice gateways, an optional gatekeeper, and multipoint control
units (MCUs). If a gatekeeper is present in an H.323 network, the terminals, gateways, and MCUs
registered with the gatekeeper form a zone. In this zone, the gatekeeper provides the following functions
for H.323 terminals, gateways, or MCUs:
• Address translation
• Admission control
• Bandwidth control
