Disassociate a Set of E.164 Numbers from a Directory Number
-----------------------------------------------------------

Use this procedure to disassociate a set of E.164 numbers from a Directory
Number (DN). When you disassociate a set of E.164 numbers from a DN,
multiple translation patterns are deleted. In other words, for each
association you delete, a translation pattern is deleted from Cisco
Unified Communications Manager.

.. note::

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

Procedure
.........

1. Log in as provider, reseller, customer, or site administrator.
2. Set the hierarchy path to the site where the E.164 numbers and DN are
   associated.
3. Choose **Dial Plan Management > Number Management > E164 Associations (N to 1 DN)**.

   An E164 Associations (N to 1 DN) table containing the following
   information is displayed:
   
.. tabularcolumns:: |p{3cm}|p{12cm}|   

+-----------+----------------------------------------------------+
| Column    | Description                                        |
+===========+====================================================+
| DN Number | The DN number                                      |
+-----------+----------------------------------------------------+
| Hierarchy | Indicates the hierarchy of the site where the E164 |
|           | number range and DN range association was created  |
+-----------+----------------------------------------------------+

4. Perform one of the following:

   * To disassociate multiple associations, click the check box in the
     far left column of the table, beside 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**.
6. Click **Yes** to confirm the disassociation.

   * The translation pattern mapping between the E.164 set and the DN is
     deleted from the Cisco Unified Communications Manager.

     The E164 number association with the DN Number will be removed 
     on the **Directory Number** list view, and in any **Lines** drop-down list
     and **Lines** displays.

   * If the site has one or more SIP Local Gateways associated with it, 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.
