Off-Hook Signaling
Description
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:
J
Called Extension Block
The called extension’s Class of Service may block incoming Off-Hook Signaling
attempts. This is beneficial to users that do not want interruptions while on a call.
J
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.
J
Manual Signaling
After reaching a busy extension, manual signaling gives the caller the choice of using
off-hook Signaling or activating other features. Extension’s 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.
J
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.
J
Off-Hook Ringing
Use this option to enable or disable an extension’s Off-Hook Signaling for incoming
calls. 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.
J
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’s
Class of Service.
J
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
