How to Enable CUCM CDR Data Collection

Enable CUCM CDR Data Collection - CUCM Administration

This is a step-by-step guide for how to enable CUCM CDR Data Collection in your Cisco Unified Communications Cluster. CDR Data Collection is not enabled by default in CUCM.

Enable CUCM CDR Data Collection

Standard CUCM CDR Service Parameters

Login to CUCM Administration on your Cisco Unified Communications Cluster.

Under the System menu, select the Service Parameters option.

On the resulting page, select one of the servers in the cluster which has the Cisco CallManager Service activated and running.

Select the Cisco CallManager Service option from the list in the Service field.

Enable CUCM CDR Data Collection - Cisco CallManager Service Parameters for CDR

One the service parameters are shown on the page, locate the System section and enable the following settings to true:

  • CDR Enabled Flag
  • CDR Log Calls with Zero Duration Flag

By default, these will likely be false. Enabling these triggers CUCM to create and store CDR records for calls processed with this CUCM Server. Enabling the CDR Log Calls with Zero Duration Flag field allows CDR records to be created for calls which do not connect or those which last for less than 1 second in duration. This data can be very helpful in measuring the performance of the system.
