Multiple Zones
If you have a large H.323 installation with more than three RADVision Gateways, you will
need more than one Gatekeeper and have more than one zone.
For Gatekeepers to direct calls to and from endpoints in other zones they have to be able to
communicate with the Gatekeepers in the other zones. The RADVision Gatekeeper can
communicate with other Gatekeepers if you define these Gatekeepers as neighbors.
The Neighbor Gatekeepers option in the Gatekeeper Setup allows you to specify the IP
addresses of Gatekeepers in other zones. You need to build a table that defines all neighbor
Gatekeepers that the current Gatekeeper can access through IP unicast. When a call is
directed to another zone, the Gatekeeper uses neighbors to resolve the destination IP
address.
Note: It is important to define all other known Gatekeepers in the network as neighbors to
allow calls from the current Gatekeeper zone to reach their zones.
