Area Code

Area codes are also known as Numbering Plan Areas (NPAs). These are necessary (for
the most part) only when dialed from outside the code area and from mobile phones.
Area codes usually indicate geographical areas within one country, although the
correlation to geographical area is becoming obsolete. For non-geographical numbers,
as well as mobile telephones outside of the United States and Canada, the "area code"
does not correlate to a particular geographic area.
To add the area code via the Web interface:
1) Choose Phone->Dialplan->Area Code.
2) Enter the Code, set the Min Length and the Max Length option, and then click the
Confirm button to save.

Block Out

The specific phone numbers can be forbidden to be called out from your IP phone.
1) Choose Phone->Dialplan->Block Out.
2) Enter the phone number, or choose the number from the list to edit/delete
3) You can not dial out the number from your IP phone unless it is removed from the
forbidden List.
