Correct Device Based Routing Class of Service to Enable Single Number Reach
---------------------------------------------------------------------------

Prior to VOSS Automate 11.5, country dial plans were configured with the
PreDBRteSel-PT route partition in the site DBRDevice Calling Seach Space (CSS).
This configuration causes problems with Single Number Reach(SNR). The correction
is to remove the PreDBRteSel-PT route partition from the site DBRDevice calling
search space, and add it to each Device Based Routing Class of Service CSS for
the site.

If you have deployed country dial plans, correct the deployed CSS using Correction
for SNR If Dial Plan Deployed.

If you have not deployed country dial plans, and have not done a new install of
VOSS Automate 11.5, correct the country dial plans schemas using Correction
for SNR If Dial Plan Not Deployed.

when the country dial plan is deployed to the customer site. 
Do this procedure for each affected country dial plan schema. 

1. Sign in as a provider administrator.                                    
#. Select **Dial Plan Management > Advanced Configuration > Dial Plan Schema**.                                                                 
#. Click the country site schema HcsGenericSite<ISOCoutnryCode>DP-V<Version>-SCH.
   Edit the instance at the provider hierarchy node.                                            
#. Click the **Calling Search Spaces** tab.                                    
#. Click the {{pwf.HcsDpUniqueSitePrefixMCR}}-<ISOCountryCode>DP-DBRDevice-CSS       
#. Click **More** under the Partitions column.
#. Click - to remove the {{pwf.HcsDpUniqueCustomerPrefixMCR}}-<ISOCountryCode>DP-PreDBRteSel-PT  
   partition (index 2).                                                    
#. Click a device base routing Class of Service CSS.
#. Click **More** under the Partitions column.                                 
#. Click + next to the last route partition.
#. For Route Partition Name, enter {{pwf.HcsDpUniqueCustomerPrefixMCR}}-<ISOCountryCode>DP-PreDBRteSel-PT, 
   where the <ISOCountryCode> is the three character country ISO code for this
   schema file (for example. USA).                                    
#. For Index, enter a value that is one greater than the current highest route
   partition index.                                                  
#. Repeat steps 8 through 12 for each device based routing Class of Service CSS
   in the site country dial plan schema.                       
#. Click **Save**.
