Hi,
could you please reveal more about your call routing? Is there any IVR involved? Queuing?
CallsOffered means within the specified half-hour interval this many calls has "gone through" the specified Call Type.
CallsAnswered means within the specified half-hour interval this many calls were answered after the specified Call Type. But this does not necessarily mean that all the calls that have been answered at this interval, had gone through the Call Type in the same interval. If, for instance, there's an IVR after the Call Type, or a prompt, that might insert enough time to have a call answering moment slip to the next interval.
CallsRouted: for this many calls the script execution terminated in the specified interval (but also this does not necessarily mean the call was answered or handled - all we know is that the script execution stopped).
In this case, in 731 cases the script execution stopped (Routed) simply because the agent answered (CallsAnswered) the call.
I hope this makes sense.
