74CHAPTER 7: GETTING MORE FROM YOUR TELEPHONE SYSTEM

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.

Using Site Codes Your administrator also can configure your telephone system to use site codes for dialing remote offices. Each site may have overlapping telephone extensions. In this example, you dial a site code first, followed by the extension at the site. Your administrator chooses the site codes.

For example, as shown in Figure 7, to call someone in Atlanta, a user in Chicago dials the site code 62 and then the extension (1000 through 3999). To reach a user in Dallas, a user in Chicago dials 63 and then the extension (1000 through 3999). The site code prevents conflicts between the remote extension and a duplicated extension at the local site.
