Branch Office dialing plan 183
Configuration example for PSTN resources at the Branch Office
IP Phones registered to the main office Call Server can be grouped into
one of two categories:
• those configured with a main office dialing plan, similar to any other
non-IP Phone at the main office
• those configured with a Branch Office dialing plan because the
telephone is physically located in a Branch Office
Customer data must first be configured to recognize numbers that are local
to each location (a standard NARS configuration issue). This example
specifically focuses on the additional changes necessary to physically
enable an MG 1000B telephone, registered with the main office Call Server,
to reach PSTN resources in the Branch Office.
Assume that the main office and Branch Office have been configured with
local numbers, such as 555-1212 or 967-1111.
Table 18 "Example dialing string, area codes, and Access Codes" (page
183)
uses the following configuration at the main office for MG 1000B
telephones to reach the PSTN.

At the main office, the following items must be configured:
• Long-distance numbers in the same area code, such as 1-613-531-1234
or 1-613-320-1234.
• Long-distance numbers at the MG 1000B are configured to go over
the Virtual Trunk and use PSTN trunks at the Branch Office, such as
1-506-555-1212 or 1-506-472-1234.
