Queues are designed to receiving calls in a call center.

A queue is like a virtual waiting room, in which callers wait in line to talk with the available agent. Once the caller called in PBX and reached the queue, he/she will hear hold music and prompts, while the queue sends out the call to the logged-in and available agents. A number of configuration options on the queue help you to control how the incoming calls are routed to the agents and what callers hear and do while waiting in the line.
