Ok, I determined that the number is not actual ASA, but apparently "avg queue time". I assume this to mean the clock starts when the caller is placed in the queue, after completing the call tree.
I figured out how to calculate the time provided, and it matches the time in History Reporting for the "avg queue time". But the time we ACTUALLY want is the "avg speed to answer", as found in History Reporting for each queue.
What table would I find the ASA from the time the caller enters the call tree?
