Enabling Cisco UCM CDR Collection

Yes, CUCM can collect CDR (Call Detail Record). This article will show you how to enable this feature (disabled by default).

Enabling CDR

Open Cisco Unified CM Administration interface:

Proceed to System → Service Parameters and select the following parameters:

  • Server — select the node to be manipulated,
  • Service — select Cisco CallManager (Active).

In the Parameters section that appears, find System and select:

  • CDR Enabled Flag * — True. This parameter indicates the call manager to create and store CDR records for each call passing through this UCM;
  • CDR Log Calls with Zero Duration Flag * — True. Enabling this parameter makes the server save the unsuccessful calls and calls that were shorter than 1 second (helpful for troubleshooting).

Don’t forget to apply the changes. Repeat this actions for each node in a cluster (if you have more than one server in System → Service Parameters → Server menu).

Additional configuration

Now let’s explore advanced parameters. On the configuration toolbar, click Advanced:

Select the following options:

  • Call Diagnostics Enabled – Enabled Only When CDR Enabled Flag is True. This parameter switches on so-called Call Management Records (CMR), which are very helpful for troubleshooting;
  • Display FAC in CDR – True. This parameter indicates whether Forced Authorization Code (FAC) should be displayed in CDR. Generally, this parameter depends on your security policies. We chose to display it;
  • Show Line Group Member DN in finalCalledPartyNumber CDR Field – True. Briefly, this parameter shows DN (directory number) of the group member that answered a call, instead of the group’s number;
  • Show Line Group Member Non Masked DN in finalCalledPartyNumber CDR Field – basically, the same as the previous one.

Open Cisco Unified Serviceability page, proceed to Tools → CDR Analysis and Reporting section. Now you can select CDR tab to use Search or export the data. Enjoy!
