Callback
Description
When an extension user calls a busy co-worker, they can leave a Callback request for a return call. The sys-
tem services Callback requests as follows:
❥ Caller at extension A leaves a Callback at extension B.
- Caller can place or answer additional calls in the mean time.
❥ When extension B becomes idle, the system rings extension A. This is the Callback ring.
❥ Once caller A answers the Callback ring, the system rings (formerly busy) extension B.
- If caller A doesn’t answer the Callback ring, the system cancels the Callback.
❥ As soon as caller B answers, the system sets up an Intercom call between A and B.
An extension user can leave a Callback at many extensions simultaneously. The system processes the Call-
backs as the extensions become free. In addition, many extensions can leave a Callback at the same exten-
sion. The system processes these Callbacks on a first-in/first-out (FIFO) basis.
If an extension user leaves a Callback request and then fails to answer within four rings, the system cancels
the Callback.
Conditions
• A system reset or power failure cancels all Callbacks system-wide.
Default Setting
• Callback enabled.
Programming
1. In 2102-01: Class of Service (page 724), check the receiving extension’s Class of Service level.
2. If yes:
- In 1512-02: Call Waiting Tones (page 657), be sure Camp-On is enabled system-wide (Yes).
- In 2116-01: Off Hook Signaling for Incoming Intercom Calls (page 749), enter 1 to enable receiv-
ing Camp-On tones at an extension.
- In 1401-03: Privacy (page 628), enter No to be sure that Privacy does not block incoming
Camp-On signals.
3. If no, do one of the following:
- To disable Camp-On system-wide, in 1512-02: Call Waiting Tones (page 657) enter No.
- To disable Camp-On for a specific extension, in 2116-01: Off Hook Signaling for Incoming Inter-
com Calls (page 749) enter 0.
- To have Privacy block incoming Camp-On tones, in 1401-03: Privacy (page 628) enter No.
With Callback, a user does not have to repeatedly call a busy extension back, hoping to find it idle.

Should an extension be able to receive Camp-On tones when a co-worker leaves them a
Callback request?
