Preparing a Cisco Unified Communications Manager Environment › Collect CDRs and CMRs

Collect CDRs and CMRs

UC Monitor requires the collection of call detail records (CDRs) and call management records (CMRs) for reporting end-of-call metrics. IP phones send CDRs and CMRs to the Cisco Unified Communications Manager. UC Monitor receives CDR and CMR data from the SPAN of traffic into and out of the Cisco Unified Communications Manager.

CDRs and CMRs contain the following information:

• When calls were made
• Where calls were directed
• Which phones made the calls
• Whether the calls were successfully completed

Use the Cisco Unified Communications Manager Administration web interface to enable CDR and CMR collection. For more information about using the web interface, consult the documentation for your version of Cisco Unified Communications Manager.

Enable CDR and CMR collection on the call servers in each monitored cluster. In some secure environments, CDR data cannot be stored on the call server. In such a case, store the CMRs and discard the CDRs.

Follow these steps:

1. Perform the following steps on each call server to enable CDR and CMR collection:
   1. Set the CDR Enabled flag to True.
   2. Set the Call Diagnostics Enabled flag to True.

      By default, both settings are disabled.

      You do not need to restart the call server for the change to take effect.

2. Perform the following steps on each call server to enable CMR collection, but disable CDR collection:
   1. Set the CDR Enabled flag to False.
   2. Set the Call Diagnostics Enabled flag to True.

Note: With CDRs and CMRs enabled, the Cisco Unified Communications Manager may enable archiving of these records. UC Monitor does not require the archiving of CDRs and CMRs.
