Using Unique Extensions to Dial Remote Offices
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).
