Troubleshoot duplicate phone count in VNQM

This issue occurs when the Cisco Unified Communications Manager (CUCM) phone tables have duplicates, or if there are multiple CUCMs with existing phones. 

• Consult your System Administrator before performing the following steps.
• This procedure requires a full back up of the SQL Server database in case you need to roll back later.

1. SQL method (Preferred)
Query to remove duplicates
Verify that your Cisco Unified Communications Manager phone tables are updated and that phones are not duplicated across the tables. Otherwise, the issue will recur on the next poll.

1. Connect to the SQL Server using Remote Desktop Connection.
2. Log in to the SQL Server Management Studio using a System Administrator account.
3. Create a Full Database Backup (SQL Server). For instructions, click here  (© 2017 Microsoft, available at https://www.microsoft.com/, obtained on 14 November 2018).
   Note: VERY IMPORTANT – DO NOT SKIP THIS STEP.
4. Expand the SQL Server and locate the SolarWinds database.
5. Right-click the SolarWinds database and select New Query.
6. Type the following query:
