[cisco-voip] Calculating MOS using CAR / CDR / SQL

[Wes Sisk]

yes, this is a pseudo classification that CAR applies based on jitter, 
packet loss, etc.  It examines the stats for the call to reach this value.

later versions of CM get a true MOS calculation from the phones in the 
CDR/CAR database in table calldetailrecorddiagnostics in columns 
origvarVQMetrics and destvarVQMetrics

sample value:
MLQK=4.5000;MLQKav=4.5000;MLQKmn=4.5000;MLQKmx=4.5000;ICR=0.0000;CCR=0.0000;ICRmx=0.0000;CS=0;SCS=0;MLQKvr=0.95

for 4.x use the CDR definitions doc to correlate rows beteween 
calldetailrecord and calldetailrecorddiagnostic:
