OutputCmrData

Unanswered Question
Apr 21st, 2010

Is there a document that tells what the fields are in the OutputCmrRecord line of the CallManager trace file?

Here is an example:

outputCmrData CMR data - 2,3,232851,3,"3313",59770361,1271856744,1103,35296,1097,35104,0,0,0,"ace5e2e2-943e-44a4-8235-818dc39c3f3a","Internal_PT","AMR-PUB-7825-Cluster","SEP0032100548A7","MLQK=3.7001;MLQKav=3.6884;MLQKmn=3.6706;MLQKmx=3.7001;ICR=0.0000;CCR=0.0009;ICRmx=0.0034;CS=2;SCS=0;MLQKvr=0.95"

I have this problem too.

I recognise some of the data as being call quality stats that are also recorded in CMR records (if it's turned on).

They are described in

CUCM Call Detail Records Administration Guide 7.1(2)

Field NamePhone Display NameD&I User Interface Text and Description
CCRCum Conceal RatioCumulative Conceal Ratio represents the cumulative ratio of concealment time over speech time that is observed after starting a call.
ICRInterval Conceal RatioInterval Conceal Ratio represents an interval-based average concealment rate that is the ratio of concealment time over speech time for the last 3 seconds of active speech.
ICRmxMax Conceal RatioInterval Conceal Ratio Max represents the maximum concealment ratio that is observed during the call.
CSConceal SecsConceal Secs represents the time during which some concealment is observed during a call.
SCSSeverely Conceal SecsSeverely Conceal Secs represents the time during which a significant amount of concealment is observed. If the concealment that is observed is usually greater than 50 milliseconds or approximately 5 percent, the speech probably does not seem very audible.
MLQKMOS LQKMOS Listening Quality K-factor provides an estimate of the MOS score of the last 8 seconds of speech on the reception signal path.
MLQKmnMin MOS LQKMOS Listening Quality K-factor Min represents the minimum score that is observed since the beginning of a call and represents the worst sounding 8-second interval.
MLQKmxMax MOS LQKMOS Listening Quality K-factor Max represents the maximum score that is observed since the beginning of a call and represents the best sounding 8-second interval.
MLQKavAvg MOS LQKMOS Listening Quality K-factor Avg8 represents the running average of scores that are observed since the beginning of a call.

I'm still looking for a description of "MLQKvr" if anyone has seen it. Just started looking.
