Dialing a Call to a
Remote Office
You can dial calls between sites in your organization that are separated
geographically but that are linked by a Wide Area Network (WAN)
connection. Each site must have an NBX system. Typical configurations
are described in the next sections.
Using Unique
Extensions
In the sample network shown in Figure 4 , everyone in the entire
organization has a unique telephone extension. Whenever you make a
call to an extension that is not located at your own site, your NBX system
sets up a connection to the NBX system at the other extension’s site.
In this example, to call a user in Dallas, a user in Chicago dials a Dallas
extension (3000 through 3999). The dial plan on the Chicago NBX system
sets up the necessary connection to the Dallas NBX system and then to
the extension at that site.
