Preparing for Installation
4 Application Gateway Hardware Installation Guide
Regardless of the network deployment chosen, the only requirements that
must be met to ensure correct operation are as follows:
The client devices (IP telephones; mobile devices) must be able to see
•
the Application Gateway on the network.
The Application Gateway must be able to see the requested content.
•
Content may be generated by servers on the local network and the
Web.
The following sections describe some possible deployment scenarios.
Connection to Application Server (In-Line)
In this configuration you connect an Application Gateway directly to an
application server, as shown in
Figure 1 Application Gateway Connected In-Line to an Application Server
This configuration is recommended for sites with one application server or
for sites that designate specific IP addresses for traffic. All traffic goes
through the Application Gateway, which passes HTML/XML requests to
the application server and handles requests from IP phones or other
microbrowser devices.
Connection to Switch
In this configuration you connect the Application Gateway and
application servers to a switch, as shown in
Figure 1.
