Hi
the below should clear your doubts
Expected Wait Time:
It actually determines how long a contact will wait before it is connected to an agent.
Formula for expected wait time:
Expected wait time = (Position of contact in queue * CSQ's average talk time) / Total number of working resources in CSQ.
The total number of working resources in CSQ = the sum of all resources in
Reserved state, Talking state, and Work state.
so Average Talk time includes the time taken to handle all the previous calls , which includes all the time call was in hold \unhold step in the script ,
