Off-Hook Signaling
Description
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.
Off-Hook Signaling for Outside Calls
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
Volume Up and Volume Down 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).
Off-Hook Signaling for Intercom Calls
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
2 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.
Off-Hook Signaling for Hotline Calls
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.
Off-Hook Signaling helps important callers get through.
