ACD Queue – The system of arrangment for automatic call distribution. It determines how to handle calls – routes and prioritizes, according to who needs to handle them. The system’s order for the call jobs in a queue depends on the priority system being used. Usually, calls are moved in the same order that they were placed on the queue. But in some cases, certain calls are given higher priority. The queue is set by handling instructions in a database.
