Use this procedure to add a new gatekeeper to an existing dial plan for redundancy purposes. You can configure a second gatekeeper as an alternate, or configure a cluster (high-capacity gatekeeper feature) with multiple gatekeepers.
Prerequisite: The baseline dial plan has been defined, the gatekeeper you want to add is in the topology, and you are in the Design View.
Select the gatekeeper group that needs a redundant device.
Add the gatekeeper to the gatekeeper group.
Specify the redundancy mechanism for the gatekeeper group (HSRP, cluster, overlap, or both).
Commit your changes to the baseline dial plan. The redundant gatekeeper information is distributed to the primary gatekeeper and any associated gateways.
Note: Configure an overlap redundant gatekeeper configuration at the gateway. Configure a clustered redundant gatekeeper configuration at the gatekeeper.
