Lift handset + Press ICM + Dial 9 + Dial outside number.Trunk (Line) Queuing / Trunk CallbackTrunk QueuingAvailability: All versions.Trunk Queueing permits an extension user to queue (wait in line)off hook for a busy trunk or trunk group to become free. The sys-tem connects the queued extension as soon as the trunk is avail-able. The user does not have to manually retry the trunk later.Trunk CallbackAvailability: All versions.After queuing for a trunk, the extension user just hangs up to con-vert the Trunk Queue into a Trunk Callback. When the trunkbecomes free, the system automatically recalls the extension. Assoon as the extension user answers the callback ring, the system connects the extension to the trunk.An extension user can leave a Trunk Callback for many trunks. The system processes the callbacksas the trunks become free. In addition, many extensions can leave a Trunk Callback for the sametrunk. The system processes the Trunk Callbacks on a first-in/first-out (FIFO) basis.If an extension user leaves a Trunk Callback request and then fails to answer the callback ringwithin four rings, the system cancels the Callback.Trunk Queuing PrioritySelected extensions can have Trunk Queuing Priority enabled in their Class of Service. If more thanone extension queues for a busy trunk, the system services the extension with Trunk Queuing Prior-ity first. If more than one extension with priority is queued for the same busy trunk, the system ser-vices the priority extensions on a first-in/first-out (FIFO) basis.Feature Quick StepsTrunk (Line) Queuing1.
