Off-Hook Signaling
Trying to get in touch with a co-worker who is busy on a call? Use
Off-Hook Signaling to let your co-worker know you're trying to get
through.
There are two types of Off-Hook Signaling: CO Off-Hook Signaling
and Intercom Off-Hook Signaling. With CO Off-Hook Signaling, an
incoming CO call will send muted ringing to your phone if you are on
a handset call or one short burst of tones if on a Handsfree Intercom
call.
Intercom Off-Hook Signaling lets you send a signal to a busy exten-
sion, then wait for a reply. The signal is one short burst of tones,
which comes over the speaker of the busy extension. In addition, the
ICM key at the busy extension flashes. The busy extension user can
choose not to reply to the signal if it is inconvenient to do so.
Signals can be sent manually or automatically. If your system requires
you to manually send the signal, you simply press a key on the dial
pad. The automatic type sends a signal any time you call a busy exten-
sion. Intercom Off-Hook Signaling cannot be sent to a busy extension
when it is using Handsfree Answerback.
You can use other options when you are trying to get through. Use
Call Waiting (page 15) to wait in line without hanging up. Or, you can
leave a Callback request for a return call (page 22). If you want, send
your co-worker a Message Waiting indication (page 43). You can also
send a Selectable Display Message to your busy co-worker, if they
have a display phone, while they stay on their initial call. They can
then send you a reverse message to your display phone asking you to
call back later, take a message, etc. (page 65).
