The GNP (Global Numbering Plan
also known as Public Numbering Plan
or E.164 Numbering Plan
) is used to set up routing rules that are common to all business groups and allow them to communicate with each other. The Global Numbering Plan is often used for interbusiness group call routing. It is separate from Business Groups.
The components of the global numbering plan are accessible from all business groups and numbering plans. Any data table that needs to be accessed from all BGs/PNPs must be placed in the GNP.
