Off Hook Signaling
n Description
When a user calls an extension busy on a call, they can send an off hook signal through the handset and
through the telephone's speaker indicating they are trying to get through. The signal is an off hook
ringing over the idle (second) line appearance. 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's Class of Service may block incoming Off Hook Signaling attempts. This is
beneficial to users that don't 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's Class of Service.
·
Manual Signaling
After reaching a busy extension, manual signalling gives the caller the choice of using Off Hook
Signaling or activating other features. Extensions without automatic signalling have manual
signalling. The users can dial a service code or press a Programmable Function Key to send Off
Hook Signaling to the called phone.
·
Selectable Off Hook Signaling Mode
The Off Hook Signal can be muted ringing, no off hook ringing, a single beep in the handset, a
beep in the speaker, or a beep in the handset - based on the caller's programming.
·
Off Hook Ringing
Use this option to enable or disable an extension's Off Hook Signaling for incoming calls (DID,
trunk). If enabled, Off Hook Signaling occurs normally. If disabled, calls queue behind the
extension's 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's Class of Service.
·
DID Call Waiting
An extension can optionally have DID calls camp on with Off Hook/Call Wait signalling, without
Off Hook/Call Wait signalling or no signalling. This is set in the called extension's Class of
Service.
·
Block Manual Off Hook Signals
This Class of Service option enables/disables a busy extension's ability to block off hook signals
manually sent from a co-worker. If disabled (not blocked), callers can dial the service code
(assigned in 11-16-04) at busy or busy/ring to signal the extension. If enabled (blocked), nothing
happens when the caller dials the service code (assigned in 11-16-04) to off hook signal.
·
Block Camp On
If an extension has Block Camp On enabled, callers to the extension cannot dial the service code
(assigned in 11-16-05) to Camp On after hearing busy or busy/ring. If the extension has Block
Camp On disabled, callers are not prevented from dialling the service code (assigned in 11-16-05)
to Camp on after hearing busy or busy/ring. This is set in the called extension's Class of Service.
