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” later in this chapter.
If you make changes to the default dial plan, you can test them by
making a simulated call. See “Testing a Dial Plan” later in this chapter.
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 are autodiscovering 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.
Importing a
User-Defined Dial Plan
To import a customer-defined (user-defined) dial plan configuration file:
1 In the NBX NetSet – Main Menu window, click Dial Plan . The Dial Plan
window appears, displaying the Operations tab (Figure 3).
2 In the field to the right of the User-Defined File radio button, 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.

Import
and reboot the system.
