Cisco Cisco Customer Voice Portal 8.0(1)

The term alternate gatekeeper has multiple meanings:

•

The ability of an H.323 endpoint, such as a gateway, to statically configure two gatekeepers
to provide a backup in the event the primary fails.

•

The ability of an H.323 endpoint to register to a GUP cluster.

Best results are achieved when Unified CVP uses the GUP cluster method of alternate gatekeeper
since solution tests have shown that proper load-balancing to Unified CVP devices is difficult
to achieve with straight alternate gatekeeper methods. Although Unified CVP itself cannot
process GUP messages, it can participate in the GUP cluster. It simply ignores GUP messages
and functions as a straight alternate gatekeeper client as described below.

The following is a simple example of Unified CVP being used in a gatekeeper cluster.
