Off-Hook Signaling

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).
