NEC 1093099 Manuale Utente

◆ Features

When a user is busy on a call, Off-Hook Signaling indicates that another caller is trying to get through. 
Off-Hook Signaling helps important callers get through, without waiting in line for the called extension to 
become free. After the user hears the off-hook signal, they can use other system features (such as Hold or 
Park) to process their active call and then answer the waiting call.

While a keyset user is on a call, Off-Hook Signaling for outside calls can be:

❥

While on a handset call, 

- A flashing green Ring/Message lamp
- A flashing red or green line/loop key
- Muted off-hook ringing 
(While Off-Hook Signaling ringing is occurring, use 

 and 

 to adjust the vol-

ume of ringing.)

❥

While on a handset or Handsfree call,

- A flashing green line/loop key
- Camp-On tones

The following chart shows when the two types of Off-Hook Signaling occur. Note that Camp-On tones occur 
for an extension when they are the exclusive recipient of the call (such as a DIL).

While an extension user is on a handset or Handsfree call, they can receive Camp-On tones from a co-worker 
that called them and dialed 

 to Camp-On. Turn to Call Waiting / Camp-On (page 28) for more on how to set 

this up. Off-hook ringing for Intercom calls is not available.

While an extension is busy on a handset call, the system provides unique handling of Off-Hook Signaling for 
calls from their Hotline partner. This unique handling occurs when the Hotline partner calls the extension by 
first pressing their Hotline key. The Off-Hook Signaling can be Camp-On tones or Voice Over. The default is 
Camp-On tones.
