Configuring a Cisco CallManager Device Pool

Gatekeeper Configuration
When configuring the Cisco CallManager gatekeeper, you are required to enter a
zone. Each Cisco CallManager will register with that zone: its zone prefix (this is
the directory number ranges), the bandwidth allowed for each call admission, and
the technology prefix for voice-enabled devices. Cisco CallManager will need the
gatekeeper to explicitly specify the IP address of the Cisco CallManager within a
single zone, and then you must disable the registration of all other IP address
ranges so it only exists within that zone. Cisco CallManager will register with the
gatekeeper using its IP address as its H.323 ID.
