Agent occupancy

This is the percentage of time agents are actively engaged in customer interactions in relation to their available or idle time. As a statistic, it’s used to calculate call center productivity. Agent occupancy considers only live logged-in time, while agent utilization considers total time at work — including logged-out time such as training.
