Your administrator chooses the site codes foryour system. In this example, you dial a site code first, followed by theextension at the site.For example, as shown in Figure 8, to call someone in Atlanta, a user inChicago dials the site code 62 and then the appropriate extension (1000through 3999). To reach a user in Dallas, a user in Chicago dials 63 andthen the appropriate extension (1000 through 3999).
