Manage Range of Internal Numbers Associated with a Range of E164 Numbers

View the Ranges of E164 Numbers Associated with a Range of Internal Numbers

Use this procedure to view the ranges of E164 numbers that are associated with a range of Internal Numbers (Directory Numbers - DNs).

On the E164 Associations ( N to N DN ) list (default menu Number Management > E164 Associations (N to N DN).

You can filter the list and change the hierarchy by selecting a link in the Located At column. A table containing this information is displayed:

Column	Description
E164 Number	The starting E164 number in the range.
DN Number	The starting internal number in the range.
Range	One of the following: 1 - To indicate that one E164 number and internal number are associated. 10 - To indicate that a range of ten numbers including the starting E164 and starting internal number are associated. 100 - To indicate that a range of 100 numbers including the starting E164 and starting internal number are associated. 1000 - To indicate that a range of 1000 numbers including the starting E164 and starting internal number are associated.
Located At	Indicates the hierarchy of the site where the E164 number range and internal number range association was created.

Associate a Range of E164 Numbers to a Range of Internal Numbers

Use this procedure to associate a single E164 number to a single internal number at a site. The association can also be done 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.

Note

• In VOSS-4-UC, the HcsSipLocalGwAddE164AssociationEVT event related to SIP Local Gateway is generated (see Considerations below).
• Only internal numbers or E164 numbers that are not currently associated are available for association.

Procedure:

1. From the E164 Associations ( N to N DN ) list (default menu Number Management > E164 Associations (N to N DN).
2. Click Add and select the site (if required).
3. Provide the following information:

Field	Description
Range	Select one of these ranges: Notes: The range values you select map to the mask value when the association translation pattern is created. For example, when 10 is selected, all E164 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 non zero number. Likewise, when 100 is selected, the E.164 number and DN end in two zeros. This pattern results in a mask of XX. 1 - To list all E164 numbers and internal numbers 10 - To list all E164 numbers and internal numbers that end in one zero (0) 100 - To list all E164 numbers and internal numbers that end in two zeros (00) 1000 - To list all E164 numbers and internal numbers that end in three zeros (000) This field is mandatory and affects what appears in the fields that follow.
E164 Number*	Choose the starting number of the range of E164 numbers from the drop-down. This field is mandatory. Notes: 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.
DN Number*	Choose the starting internal number from the drop-down menu. This field is mandatory. Notes: 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 that were added at either customer or site level. You cannot associate internal numbers that begin with the prefix ‘*’ (asterisk) or ‘#” (hash).

4. Click Save.

Considerations:

• When listing the Number Inventory and displaying an internal number, the E164 Number format is as listed in E164 Column - Number Inventory List.
• A translation pattern that is used to route inbound PSTN calls to their associated internal numbers is created on the Unified CM. This pattern is the mapping between the E164 range and internal number range.
• If the association is performed at site level the translation pattern will only be added to the Unified CM referenced by the site’s network device list (NDL).
• If the association is performed at customer level then the translation pattern will be added to all of the Unified CMs that exist for the customer.
• If the site has one or more SIP Local Gateways associated with it, 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.

Disassociate a Range of E164 Numbers from a Range of Internal Numbers

Use this procedure to disassociate a range of E164 numbers from a range of internal numbers.

Note

In VOSS-4-UC, the HcsSipLocalGwDelE164AssociationEVT event related to SIP Local Gateway is generated as a result.

Procedure:

1. From the E164 Associations ( N to N DN ) list (default menu Number Management > E164 Associations (N to N DN).
2. You can change your hierarchy if needed.
3. An E164 Associations (N to N DN) table containing this information is displayed:

Column	Description
E164 Number	The starting E164 number in the range.
DN Number	The starting DN number in the range.
Range	1 - To indicate that one E164 number and internal number are associated 10 - To indicate that a range of ten numbers including the starting E164 and starting internal number are associated 100 - To indicate that a range of 100 numbers including the starting E164 and starting internal number are associated 1000 - To indicate that a range of 1000 numbers including the starting E164 and starting internal numbers are associated
Located At	Indicates the hierarchy of the site where the E164 number range and internal number range association was created.

4. Perform one of these options:
   • To disassociate multiple ranges, select the check boxes in the far left column of the table for the ranges you want to disassociate.
   • To disassociate one range, click its row in the table. The details about the association appear.
5. Click Delete.
6. Click Yes to confirm the disassociation.

Considerations:

• The translation pattern mapping between the E.164 range and internal number range is deleted from Unified CM.

  The E164 number association with the internal number will be removed on the Number Inventory list view display and in any Lines drop-down list and Lines displays.

• If the site has one or more SIP Local Gateways associated with it, the HcsSipLocalGwDelE164AssociationEVT event is generated. If enabled, the IOS Command Builder generates the default IOS commands associated with the event for each SIP Local Gateway.
