E164 Associations ( N to 1 DN )

Overview

This topic describes managing single internal numbers associated with a range of E164 numbers.

View E164 Associations (N to 1 DN)

This procedure displays sets of E164 numbers associated with a single internal number (directory number, or DN).

1. Go to (default menus) Number Management > E164 Associations (N to 1 DN).

2. On the E164 Associations ( N to 1 DN ) list, view E164 Associations (N to 1 DN).

   Note

   You can filter the list and change the hierarchy by selecting a link in the Located At column.

   The table describes column data in the E164 Associations (N to 1 DN) list view:

   Column	Description
   DN Number	The associated internal number (directory number).
   Located At	The hierarchy of the site where the E164 number range and internal number association was created.

3. Click on a directory number in the list to view its details.

   The page displays read-only details about the E164 Association (N to 1 DN) configuration (the sets of E164 numbers that are associated with the internal number):

   DN Number	The number you’re viewing.
   Primary E164	Displays the E164 number associated to the internal number in the Number Inventory. Other E164s are indicated as [x] showing that there are more associated E164s to this internal number but their details are only available when opening the relevant Number Inventory.

Add E164 Association (N to 1 DN)

This procedure associates multiple E164 numbers (a set of E164 number) to a single internal number, at a site. For example, you could associate a set of E164 numbers for the sales department with an attendant’s internal number.

Note

You can also perform association in ranges of 10, 100, and 1000, on a one-to-one basis. These associations create Direct Dial Inward (DDI) associations so that incoming PSTN numbers are routed to internal numbers.

You can optionally specify a primary E164 number to associate with the internal number. This is useful when performing an internal number to E164 translation (for example, when provisioning translation rules for LBO gateways) and the internal number is associated to more than one E164 presentation.

You can only associate internal numbers or E164 numbers that are not currently associated.

Prerequisites:

• Number management must be enabled for the customer.

Perform these steps:

1. Go to (default menu) Number Management > E164 Associations (N to 1 DN) to open the list view.

2. Choose the site (if required).

3. In the E164 Associations ( N to 1 DN ) list view, click the Plus icon (+) to add a new record.

4. Configure E164 Association ( N to 1 DN ). The table describes configuration options:

Field	Description
DN Number	Choose an internal number. If the association is performed at Customer level, the drop-down only shows internal numbers that were added at Customer level. If the association is performed at Site level, the drop-down shows internal numbers added at either Customer or Site. You can’t associate internal numbers that begin with the prefix ‘*’ (asterisk) or ‘#” (hash).
E164 Ranges	Click the Plus icon (+) to add one or more sets of E164 numbers. These E164 numbers do not need to be contiguous. For each E164 number you add, choose an E164 range and the E164 number, as follows: E164 Range Choose an E164 range, either 1, 10, 100, or 1000. The range value you choose maps to the mask value when the association translation pattern is created. For example, choose 10 to list all E164 numbers and internal numbers ending in 0. The mask affects all digits 0 to 9, so you can’t start the mask on a non-zero number. When 100 is chosen the E164 number and internal number end in two zeros, resulting in a pattern with a mask of XX. 1 - to list all E164 numbers 10 - to list all E164 numbers ending in one zero (0) 100 - to list all E164 numbers ending in two zeros (00) 1000 - to list all E164 numbers that end in three zeros (000) This field is mandatory and affects what appears in the E164 Number field.
E164 Number	Mandatory. Choose the starting number of E164 numbers. If the association is performed at customer level, the drop-down only shows E164 numbers that were added at customer level. If the association is performed at site level, the drop-down contains E164 numbers that were added at either customer or site level provided the country matches the site’s country.
Primary E164	Optional. Fill out the primary E164 number to associate with the internal number. Ensure the E164 number you enter starts with \+ and falls within the range you specified in in E164 Range
Dial Plan Model Selection	This field displays only when the Enforce HCS Dialplan Rules setting in the Global Settings is set to False Defines the translation pattern template configured in the dial plan modeling tool. The values for the pattern, transform mask, and associated range masking are hard coded in the workflow. +1555 111 5555 (Range 10) = +1555 111 555X Other values, such as partition and CSS) come from this template. The translation pattern must have its description set to display in this drop-down.

5. Save your changes.

   Note

   • When listing the Number Inventory and displaying an internal number, the E164 number format is as listed in E164 Numbers in the Number Inventory.

   • One or more translation patterns are created on the CUCM. The translation patterns are the mappings between the set of E164 numbers and the single internal number, and are used to route inbound PSTN calls to their proper internal numbers.

     When you associate a set of E164 numbers to a single internal number, multiple translation patterns are created (each DN-to-E164 range association results in a translation pattern being created on the CUCM).

   • If the association is performed at Site level, the translation pattern is only added to the CUCM referenced by the site’s network device list (NDL).

   • If the association is performed at Customer level, the translation pattern is added to all of the CUCMs that exist for the customer.

   • If the site is associated with one or more SIP Local Gateways, the HcsSipLocalGwAddMultiE164AssociationEVT event is generated. If enabled, the IOS Command Builder generates the default IOS commands associated with the event for each SIP Local Gateway.

Delete an E164 Associations (N to 1 DN) Association

This procedure disassociates a set of E164 numbers from an internal number.

Note

• When disassociating a set of E164 numbers from an internal number, multiple translation patterns are deleted. For each association you delete, a translation pattern is deleted from the CUCM.

  In VOSS Automate, the HcsSipLocalGwDelMultiE164AssociationEVT event related to SIP Local Gateway is generated as a result.

• If the Local Gateway is set up to override the Voice Translation limit and the Enable Command Builder setting is enabled, disassociation will fail if it exceeds the default Voice Translation limit. In this case, first disable the Enable Command Builder setting.

1. Go to (default menu) Number Management > E164 Associations (N to 1 DN).

2. Change the hierarchy, if required.

3. In the E164 Associations ( N to 1 DN ) list, view the following details:

Column	Description
DN Number	The internal number.
Located At	The hierarchy of the site where the E164 number range and internal number range association was created.

4. Choose an option:

   • To disassociate multiple associations, click the check box in the far left column of the table, next to the numbers you want to disassociate.

   • To disassociate one association, click its row in the table. The details about the association appear.

5. Click Delete, then click Yes to confirm the disassociation.

   Note

   • The translation pattern mapping between the E164 set and the internal number is deleted from the CUCM.

     The E164 number association with the internal number is removed from the Number Inventory list view, and from any Lines drop-downs and Lines displays.

   • If the site is associated with one or more SIP Local Gateways, the HcsSipLocalGwDelMultiE164AssociationEVT event is generated. If enabled, the IOS Command Builder generates the default IOS commands associated with the event for each SIP Local Gateway.
