Associate a Set of E.164 Numbers to One Directory Number

Use this procedure to associate a set of E.164 numbers with one Directory Number (DN) at a customer or site. For example, you could associate a set of E.164 numbers for the sales department with an attendant’s DN.

If you create the association at a site, you can mix customer-level DNs and E.164 numbers with site-level DNs and E.164 numbers.

You can optionally specify a primary E.164 number to associate with the DN. This step can be useful when you perform a DN-to-E.164 translation (for example, when provisioning translation rules for LBO gateways) and the DN is associated to more than one E.164 presentation.

Note

  • You cannot associate numbers if Number Management has been disabled for the customer.
  • Only DNs or E.164 numbers that are not currently associated are available for association.

Procedure

  1. Log in as provider, reseller, customer, or site administrator.
  2. Set the hierarchy path to the customer or site where you are associating a set of E.164 numbers with one DN.
  3. Choose Dial Plan Management > Number Management > E164 Associations (N to 1 DN).
  4. Click Add.
  5. From the DN Number drop-down, choose an extension number. This field is mandatory.
  6. In the E164 Ranges table, click + as required, to add multiple sets of E.164 numbers. The E.164 numbers do not need to be contiguous. Provide the following information:
Field Description
E164 Range

Choose one of these ranges:

Note:

The range values you choose map to the mask value when the association translation pattern is created. For example, when 10 is chosen, all E.164 numbers and directory numbers that end in 0 are listed. The mask affects all digits 0 to 9, so you can’t start the mask on a nonzero number. Likewise, when 100 is chosen, the E.164 number and DN end in two zeros. This pattern results in a mask of XX.

  • 1 - To list all E.164 numbers
  • 10 - To list all E.164 numbers that end in one zero (0)
  • 100 - To list all E.164 numbers that end in two zeros (00)
  • 1000 - To list all E.164 numbers that end in three zeros (000)

This field is mandatory and affects what appears in the E.164 Number field.
E164 Number Choose the starting number of E.164 numbers. For a customer-level association, customer-level E.164 numbers are available. For a site-level configuration, both customer-level and site-level E.164 numbers are available. This field is mandatory.
  1. In the optional Primary E164 field, enter the primary E.164 number to associate with the DN. Make sure the E.164 number you enter starts with + and falls within the range you specified in the E164 Range drop-down.
  2. Click Save.
    • When listing the Directory Number Inventory and displaying a directory number, the E.164 number format is as listed in View Directory Number Inventory.
    • For a site-level association, one or more translation patterns that are used to route inbound PSTN calls to their proper DN are created on the Unified CM. These patterns are the mappings between the set of E.164 numbers and the single directory number. When you associate a set of E.164 numbers to a single DN, multiple translation patterns are created; that is, each DN-to-E.164 range association results in a translation pattern being created on Cisco Unified Communications Manager.
    • For a customer-level association, the translation patterns are created on each Unified CM cluster that has a dial plan provisioned.
    • For a site-level association, if the site has one or more SIP Local Gateways associated with it, the HcsSipLocalGwAddMultiE164AssociationEVT is generated. If enabled, the IOS Command Builder generates the default IOS commands associated with the event for each SIP Local Gateway.
    • For a customer-level association, if the E.164 number has the same country as any SIP Local Gateway configured for the customer, the HcsSipLocalGwAddE164AssociationEVT event is generated. If enabled, the IOS Command Builder generates the default IOS commands associated with the event for each SIP Local Gateway.
