these destinations, and which telephone numbers to dial to reach these
destinations.
The dial plan configuration file is an ASCII text file that implements the
dial plan and specifies pretranslation (digit manipulation). The system is
shipped with several default dial plan configuration files, typically, a
3-digit and a 4-digit file for each supported country.
The dial plan configuration file includes several tables:
Internal — Must be table ID 1
■
Incoming — Must be table ID 2
■
Least Cost Routing — Must be table ID 3
■
Routes
■
Pretranslators
■
You can create additional tables if necessary.
Each dial plan table consists of a series of entries, each of which includes
a sequence of digits and the action the system performs in response to
sending or receiving those digits. For more information about the
Internal, Incoming, and Least Cost Routing dial plan tables, see
Tables" on page
You can access the dial plan configuration file and manage dial plan
operations, tables, pretranslators, and extension lists through the NBX
NetSet administration utility. However, if your dial plan is larger than
32,000 characters, you cannot use the NBX NetSet utility to edit it. You
must export the dial plan, edit it, and then import it.
Before you configure the dial plan, make sure that you understand these
