Which of the following activity codes would indicate an agent is unavailable?

The activity code that indicates an agent is unavailable is "Unavailable." This code is specifically designed to reflect moments when an agent is not able to handle incoming contacts. This could be due to various reasons, such as taking a personal break or being occupied with tasks that prevent them from responding to customers. Using this code allows management to accurately track and report on agent availability, crucial for effective workforce management.

In contrast, "On Queue" indicates that the agent is available and ready to receive contacts, while "Training" signifies that the agent is engaged in learning or development activities but technically may still be considered unavailable for customer interactions. "Break" tells that the agent is taking a brief rest, which also contributes to their unavailability but specifies the nature of the downtime rather than a pause from all interactions. Only the "Unavailable" code categorically communicates an agent's status as not being able to take calls or messages at that moment.
