This version of the Cisco UCM stores its call records in a Microsoft SQL Server database. However, by default, this functionality is not enabled. To enable it, the following settings must be configured on the Publisher using the Service Parameters Configuration window:

CDR Enabled
CDR Log Calls With Zero Duration Flag
Call Diagnostics Enabled
This version of the UCM outputs its call records to a table named CallDetailRecord in a database entitled CDR.

You need the following information to apply collector settings:

The username and password to connect to the CDR database.
