Line Queueing permits an extension user to queue (wait in line) on hook for a busy line or Line Group to become free. The system connects the queued extension as soon as the line is available. The user does not have to manually retry the line later.
After queuing for a line, the extension user just hangs up to convert the Line Queue into a Line Callback. When the line becomes free, the system automatically recalls the extension. As soon as the extension user answers the callback ring, the system connects the extension to the line.
An extension user can leave a Line Callback for many lines. The system processes the callbacks as the lines become free. In addition, many extensions can leave a Line Callback for the same line. The system processes the Callbacks on a first-in/first-out (FIFO) basis.
If an extension user leaves a Line Callback request and then fails to answer the callback ring, the system cancels the Callback.
Selected extensions can have Line Queuing Priority enabled in their Class of Service. If more than one extension queues or leaves a Callback for a busy line, the system services the extension with Line Queuing Priority first. If more than one extension with priority is queued for the same busy line, the system services the priority extensions on a first-in/first-out (FIFO) basis.
