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.
