The call server supplies the information needed by the Application
Gateway to create an IP/DN map. When the Application Gateway detects
that an IP telephone has come online, the Application Gateway obtains
from the IP telephone its IP address and uses that address to look up the
phone's extension in the IP/DN map. Extensions in the IP/DN map are
available to the administrator for the creation of custom zones.
The Application Gateway also imports departments from the Directory
server to create a zone for each department. The Application Gateway
synchronizes with those servers and manages IP phone requests to send
pages.
The Application Gateway must be on the same LAN segment as the
Note
call server.
When you add an Application Gateway to a cluster, the zones on that
Application Gateway are replaced by the cluster-wide zone list. Therefore,
when you configure Zone Paging for a cluster it is best to follow these
general steps:
Configure each Application Gateway to be included in the cluster,
1.
including the IP/DN mapping, synchronization, and the multicast IP
address range.
Add all member Application Gateways to the cluster.
2.
Synchronize the cluster.
3.
Create the zones to be used by the cluster.
4.
Zone Paging operation with a cluster is the same as with a single
Application Gateway, except as follows:
For zone paging across a cluster, multicasting must be enabled on the
•
router and each Application Gateway must have a different multicast
IP address range specified on the
