116 N Section 3: Features
Feature Quick Steps
To place a call over a trunk group:
1. Lift handset + Press ICM + Dial 9 + Dial outside number.

Trunk Queuing

When all trunks are busy,
Trunk Queuing lets a user
wait in line for a trunk to
become free.

Trunk Callback

Trunk Callback will
automatically call the user
back when a trunk is
available.
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.

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.

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
