Trunk (Line) Queuing / Trunk Callback
Trunk Queuing
Availability: 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 Callback
Availability: 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 trunk
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 trunk.
An extension user can leave a Trunk Callback for many trunks. The system processes the callbacks
as the trunks become free. In addition, many extensions can leave a Trunk Callback for the same
trunk. 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 ring
within four rings, the system cancels the Callback.
Trunk Queuing Priority
Selected extensions can have Trunk Queuing Priority enabled in their Class of Service. If more than
one 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.
