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

For example, as shown in Figure 6, to call someone in Atlanta, a user in Chicago dials the site code 62 and then the appropriate extension (1000 through 3999). To reach a user in Dallas, a user in Chicago dials 63 and then the appropriate extension (1000 through 3999). The site code prevents conflicts between the remote extension number and a duplicated extension number at the local site (Chicago).
