Extensions in the IP/DN map areavailable to the administrator for the creation of custom zones.The Application Gateway also imports departments from the Directoryserver to create a zone for each department. The Application Gatewaysynchronizes with those servers and manages IP phone requests to sendpages.Note The Application Gateway must be on the same LAN segment as thecall server.Paging Setup and Operation with ClustersWhen you add an Application Gateway to a cluster, the zones on thatApplication Gateway are replaced by the cluster-wide zone list. Therefore,when you configure Zone Paging for a cluster it is best to follow thesegeneral steps:1. Configure each Application Gateway to be included in the cluster,including the IP/DN mapping, synchronization, and the multicast IPaddress range.2. Add all member Application Gateways to the cluster.3. Synchronize the cluster.4. Create the zones to be used by the cluster.Zone Paging operation with a cluster is the same as with a singleApplication Gateway, except as follows:• For zone paging across a cluster, multicasting must be enabled on therouter and each Application Gateway must have a different multicastIP address range specified on the
