Calls
Trunk Queuing
The Trunk Queuing features complete calls for you to outside numbers
when all available trunks (outside lines) have been busy.
Trunk Callback Queuing
Trunk Callback Queuing lets you hang up and have the
communications server call you back with triple rings when a trunk
becomes free for an outside call. When you then answer, the
communications server automatically dials the number.
To queue for a
trunk callback ➩ Listen for the queuing tone.
➩ Hang up. The Callback status light will
turn on.
Note: If you receive a busy tone instead of a queuing tone, Trunk
Callback Queuing is not available.
To accept the
trunk callback ➩ Listen for the triple rings.
If you have a display telephone, FREE is
displayed.
➩ Answer the telephone. The
communications server will automatically
place your call.
You will hear the external number that you
called begin to ring.
To cancel trunk
callback queuing
from a display
telephone ➩ Press the Callback (CALLBCK) key until
the auto-callback request you wish to
cancel is displayed. The status light next to
the Program key turns on, indicating that
your telephone is in program mode.
