I have tested the following stat,
When the agent receives an inbound call, the current number of ready agents will be
decreased by 1. But for these stat, the value is not decreasing
Current_Number_Wait_Status
Objects : GroupAgents,GroupPlaces
Category : CurrentNumber
MainMask : WaitForNextCall
Subject : DNAction
whether MainMask->WaitForNextCall is not applicable only with
category->DNAction.
