Off-Hook Signaling 2 - 751
O
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/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.
