[cisco-voip] Percentage of good calls went below the limit specified on Apr 16, 2008

[Ryan Ratliff]

The CAR classifications for QOS are all based on the CMR records.   
You can look in the CAR config to see what the thresholds are for  
each classification level but if any one of the metrics is below Good  
then the whole call is classified at that lower level.  The last time  
I looked it classified on jitter, lost packets, and maybe one more  
thing.

Hello all, we have a small CUCM system with about 200 phones with an
average of 2 or 3 active calls at the time going through our gateway.
CAR is set up like this:
Daily QoS Parameters
  When Good Calls lesser than*   20 %
  When Poor Calls greater than*   30 %

In the docs I see: "when good calls represent less than 20 percent of
all calls per day, an alert gets sent. The default for poor calls
specifies greater than 30 percent, meaning that when poor calls
represent more than 30 percent of all calls per day, an alert gets
sent."
(http://www.cisco.com/univercd/cc/td/doc/product/voice/c_callmg/5_0/serv
ice/serv504/car/carrport.pdf) so, the way I'm interpreting this, it's
saying that 80% of our calls are bad. How is it determining this? we
know the calls are fine and nobody has been complaining.
TIA
