Managing the Dial Plan Configuration File 47
International Dial Plan Issues
Several international dial plan issues warrant attention. See these topics:
Customizing an International Dial Plan. If there is no customized
dial plan for your country, you may need to modify the default dial plan.
See “
Modifying a Dial Plan Configuration File” on page 51. If you edit the
default dial plan, you can test the changes by making a simulated call.
See “
Testing a Dial Plan” on page 49.
Autodiscovering Internal Telephones. The default dial plan for the
NBX 100 allows you to allocate internal telephones to extension numbers
100 through 449. The default dial plan for the SuperStack 3 NBX system
allows you to allocate internal telephones to extension numbers 1000
through 3999. If you autodiscover your company’s internal telephones,
Auto Discovery usually begins at number 100 or 1000. However, for
some countries, internal telephones begin at a higher number to allow
you to directly dial numbers of “national importance.” Auto Discovery
allocates telephone extensions numbers within this range. For more
information on Auto Discovery, see “Using Auto Discovery for Initial
System Configuration” in the NBX Installation Guide.
Dialing Outside Lines. To obtain an outside line, dial 9 or 0 as
appropriate for your country.
WARNING: You must first obtain an outside line before you can dial
emergency numbers.

1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan
window appears, displaying the Operations tab.
2 In the User-Defined File box, enter the path and name of the user-defined
configuration file, or click
Browse to find the file that you want.
The NBX system has no predefined location for dial plan configuration
files. You can specify any directory or path that you want.
3 Click
Import and reboot the system.
CAUTION: When you import a dial plan configuration file, the
NBX system immediately implements the dial plan. You are always
warned that the system may become inoperative. The system becomes
inoperative only if you have manually modified a dial plan and have
