Planning the System
Understanding the Dial Plan

Prepending the location prefix to dialed
numbers
Use the Insert Digits field on the Uniform Dial Plan Table screen to assign the location prefix from the
caller’s location on the Locations screen. The system adds the location prefix digits to the front of the
called number. The switch then analyzes the entire dialed string and routes the call based on the
administration on the
Dial Plan Parameters screen.
•
Non-IP phones and trunks inherit the location number of the hardware they are connected to (for
example, the cabinet, remote office, or media gateway).
•
IP phones indirectly obtain their location number.
— A location number is administered on the IP Network Region screen that applies to all
phones in that IP region.
— If a Location field is left blank on an IP Network Region screen, an IP phone derives its
location from the cabinet where the CLAN board is that the phone registered through.
•
IP trunks obtain their location from the location of its associated signaling group. Either direct
administration (only possible for signaling groups for remote offices), or the ways described for
IP phones, determines the location.
Other options for the dial plan
You can establish a dial plan so that users only need to dial one digit to reach another extension. You can
also establish a dial plan that allows users to dial, for example, three digits to reach one extension, and
four digits to reach another. This is particularly useful in the hospitality industry, where you want users to
be able to simply dial a room number to reach another guest. For more information, see
Single-Digit
Dialing and Mixed Station Numbering on page 1672.
Adding feature access codes
As your needs change, you may want to add a new set of FAC for your system. Before you can assign a
FAC on the Feature Access Code screen, it must conform to your dial plan.
In our example, if you want to assign a feature access code of 33 to
Last Number Dialed
, first you need
to add a new FAC range to the dial plan.
To add a FAC range from 30–39:
1
