Chapter 2
Application Gateway and
Broadcast Server Operation
As shown in the following illustration, Broadcast Server communicates
only with the Application Gateway. The Application Gateway provides
Broadcast Server with device information and manages all communication
with other servers and IP telephones. The Application Gateway also
transforms alerts so that they are in the appropriate format for display and
delivery to IP telephones.
Note Sites using a cluster of Application Gateways should configure all
Application Gateways in the cluster with the same Broadcast Server.
The Phone Applications Suite Configuration Guide explains the IP phone
setup required for Broadcast Server. To enable communication between
the Application Gateway and Broadcast Server, you specify in the
Application Gateway Administration Tool the base URL where Broadcast
Server is running. That is the only information that the Application
Gateway needs to register with Broadcast Server.
