Only a subset of some phones and MGCP gateways report CMR data.  If you are only using h323 phones, trunks, gateways then there will be no CMR information. If you are using CM as SME then there will be no CMR information. Any more information about the environment?

I have enabled the following on CUCM that is doing call processing only. 


CDR Enabled Flag Required Field                     "True"
CDR Log Calls with Zero Duration Flag              "True"
Digit Analysis Complexity Required Field          "StandardAnalysis"
Call Diagnostics Enabled Required Field           "Enabled only when CDR Enabled flag set to True"


However, in CDR record, no media information is captured for each call. It is always shown as null. 

I suppose with "Call Diagnostics Enabled" on, it will information such as MOS value of each call, etc.
