Realization of the calls in queue will be done by mapping each precedence level to a specific attendant queue. Each queue has its own key on the attendant console. The administrator has to assign the description text for the different precedence levels to the corresponding call queue keys on the attendant console. The attendant has the ability to get the calls with the higher precedence first by hitting the key for the queue of the higher precedence first. This function is available on AC-Win-MQ only.
