Introduction to E164 inventory management
--------------------------------------------

.. index:: Flowchart;E164 Inventory Management (Provider)

E164 inventory management uses translation patterns in Automate to provide a Direct Dial-In (DDI)/Direct Inward Dialing (DID)
mapping to internal numbers.

DDI-to-DN mapping allows you to route incoming PSTN calls to the appropriate internal number.

Managing the E164 inventory involves: 

* Viewing, adding, or deleting E164 number inventory
* Associating a range of E164 numbers to a range of internal numbers
* Viewing an associated range of E164 numbers to a range of internal numbers
* Disassociating a range of E164 numbers from a range of internal numbers
* Associating a range or set of E164 numbers to a single internal number
* Disassociating a range or set of E164 numbers from a single internal number
* Viewing single internal number associations

The E164 inventory is available in the drop-down menus for Site Published
Number and Emergency Number when creating a Site Dial Plan.
