[cisco-voip] How to capture voice quality information in CDR?

[Ki Wi]

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.
