Update the USA Device-Based Routing Dial Plan
---------------------------------------------

Use this procedure if you deployed the United States country dial plan using
VOSS-4-UC 10.1(1) and are using Device-Based
Routing. Update the calling search spaces (CSS) for each customer that uses the
United States dial plan. Update one customer-level CSS and one site-level CSS for
each USA site.

.. note::

   Perform this procedure only once. For example, if you performed this procedure
   when you upgraded to Unified CDM 10.6(1), do not perform it again when upgrading
   to a later release.                              


1. Log in to Cisco Unified Communications Manager.
2. Navigate to **Call Routing > Class of Control > Calling Search Space**.
3. Find the calling search space where the CSS Name ends with USADP-DBRDevice-CSS.

   .. note::

      Records for each of your USA sites appear in the  following format:
      Cu<customerId>Si<siteId>-USADP-DBRDevice-CSS.
4. Edit each calling search space to include the pre-device-based route selection
   partition instead of the device-based route selection partition:

   a. Remove the following partition: Cu<customerId>-USADP-DBRteSel-PT.                    
   b. Add the following partition: Cu<customerId>-USADP-PreDBRteSel-PT.                 
   c. Click **Save**.                                          
5. Find the calling search space where the CSS Name ends with USADP-DBRteSel-CSS.

   .. note::

      Records for each of your USA sites appear in the following format:
      Cu<customerId>Si<siteId>-USADP-DBRteSel-CSS.     
6. Edit this calling search space to include the device-based route selection
   partition instead of the line-based route selection partition:

   a. Remove the following partition: Cu<customerId>-USADP-LBRteSel-PT.                    
   b. Add the following partition: Cu<customerId>-USADP-DBRteSel-PT.
