You can configure the following parameters in the General section when you create or modify a dialplan:
Name: Enter a name to easily identify the dialplan, e.g., Stuttgart office.
Country code: Enter the country code without any prefixes for the country in which the computer with the
installed Diva SIPcontrol is located, e.g. 1 for US or 49 for Germany.
North-American
numbering plan:
Select this option if the North American numbering plan (NANP) is needed for your
configuration. With the NANP, a city can have more than one area code, consequently it is
not evident how to dial a number in the same city. Diva SIPcontrol allows you to enter
various area codes that are considered local and should be called without long-distance
prefix. See Area code and Other local areas for more information.
Area code: If you do not use the North American numbering plan (NANP), enter the area code without
the leading zero here. If the NANP is needed for your configuration, enter the code for the
home area here and enter the codes for the other local areas in Other local areas.
If you need to use the NANP, you can choose between the following number transmission
methods:
With national prefix: The long-distance code is added to the number.
Local: The number is transmitted without any area code.
Without national prefix: The number is transmitted without the long-distance prefix.
Other local areas: You can enter various area codes that are considered local and should be called without
the long-distance prefix. This is the case in some countries where the North American
numbering plan is deployed, e.g., in the USA. With the NANP, a city can have more than
one area code; consequently, it is not clear how to dial a number in the same city.
Base number: Enter your subscriber or trunk number without a country and area code. If you use MSNs,
leave this field empty and enter the length of the MSNs in Maximum extension digits.
Maximum extension
digits:
Specify the maximum number of extension digits. Use the "arrow up" and "arrow down"
buttons to do so.
International prefix: Enter the international prefix for your country, e.g., 00.
National prefix: Enter the digits of the national prefix, e.g., 0 in Germany.
