Call Management Records - CMR

Call Management Records - CMR

Last updated on Dec 12, 2017 by dre in category CDR Reporting & Call Analytics

Cisco Unified Communications Manager generates call management records (CMRs) which can be used for post-processing activities such as call quality metrics (jitter, Latency, ect), generating billing records, tracking usage activity and network analysis.
 
You can configure CMRs on the Service Parameters Configuration window in Cisco Unified CM Administration. To access the Service Parameters Configuration window, open Cisco Unified CM Administration and choose System > Service Parameters. Choose the Advanced button to display the complete list of Service Parameters. Select the Call Diagnostics Enabled parameter.
 
This parameter determines whether the system generates CMRs, also called call diagnostic records. Valid values specify Disabled (do not generate CMRs), Enabled Only When CDR Enabled Flag is True (generate CMRs only when the CDR Enabled Flag service parameter is set to True), or Enabled Regardless of CDR Enabled Flag (generates CMRs without regard to the setting in the CDR Enabled Flag service parameter). This represents a required field. The default value specifies Disabled.
 
I have Enabled CMR, Why am I not seeing any data?
 
Cisco has identified a bug in which there is no CMR support for SIP endpoints and trunks.
 
Cisco Bugs:
 
CSCub07733: Update CMR records for calls from sip trunks
 
CSCub16565: Update documents that there is no CMR support for sip endpoints & trunks
 
As a work around you can change phones protocol from SIP to SCCP, however there is currently no known work around for Cisco Jabber.
