Off-Hook Signaling
Description
Off-Hook ringing alerts a Multiline Terminal user that an incoming outside call is ringing to that station
during another call. Off-Hook Signaling helps important callers get through, without waiting in line for
the called extension to become free. The system provides the following Off-Hook Signaling options:
• Called Extension Block
The called extension Class of Service may block incoming Off-Hook Signaling attempts. This is
beneficial to users that do not want interruptions while on a call.
• Automatic Signaling
Calling a busy extension automatically initiates Off-Hook Signaling. This option is useful to
receptionists, operators and others that must quickly process calls. This is set in the called
extension Class of Service.
• Manual Signaling
After reaching a busy extension, manual signaling gives the caller the choice of using Off-Hook
Signaling or activating other features. Extensions without automatic signaling have manual
signaling. The users can dial a service code or press a
Programmable Function
key to send Off-
Hook Signaling to the called telephone.
• Selectable Off-Hook Signaling Mode
The Off-Hook Signal can be muted ringing, no off-hook ringing or a beep in the handset-based on
the caller’s programming.
• Off-Hook Ringing
Use this option to enable or disable an extension Off-Hook Signaling for incoming calls. If enabled,
Off-Hook Signaling occurs normally. If disabled, calls queue behind the extension busy line
appearance and the user gets no Off-Hook Signaling indication. The second line appearance stays
idle. The caller hears ringback tone while their call waits. This is set in the called extension Class of
Service.
• DID Call Waiting
An extension can optionally have DID calls camp-on with Off-Hook/Call Wait signaling, without Off-
Hook/Call Wait signaling or no signaling. This is set in the called extension Class of Service.
• Block Manual Off-Hook Signals
This Class of Service option enables/disables a busy extension ability to block off-hook signals
manually sent from a co-worker. If disabled (not blocked), callers can dial
*
at busy or busy/ring to
signal the extension. If enabled (blocked), nothing happens when the caller dials
*
to off-hook
signal.
• Block Camp-On
If an extension has Block Camp-On enabled, callers to the extension cannot dial 2 to Camp-On after
hearing busy or busy/ring. If the extension has Block Camp-On disabled, callers are not prevented
from dialing 2 to Camp-On after hearing busy or busy/ring. This is set in the called extension Class
of Service.
Conditions
• An extension user cannot Camp-On to a busy extension or leave a callback if Off-Hook Signaling
has already gone through. Off-Hook Signaling allows an extension to block a caller’s ability to dial #
to camp-on.
• You cannot send off-hook signals to an extension busy on a Handsfree (Speakerphone) call. The
called extension large LED flashes fast, with no ringing.
• The setting of PRG 20-13-06 affects the BLF display for Hotline and Reverse Voice Over. Refer to
Hotline on page 1-353
and
Reverse Voice Over on page 1-625
features for additional information.
• You cannot send off-hook signals to an extension that is already receiving a voice announcement.
