Recently I used Cisco Unified Service Statistic Manager to monitor the call count (call volume) of our E1 trunks of our two voice gateway, however I noticed that the report is not consistent. Below my observation. I also attached the two graph files report for reference.
#1 Report. April 11, 2012 (between 12:00AM to 11:00PM) Report
Voice Gateway 1
Maximum Call = 8
Minimum Call = 1
Average Call = 4.731 - why there is a point here, not whole #?
