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
fi rst-in/ fi rst-out (FIFO) basis.
If an extension user leaves a Callback request and then fails to answer within four rings, the system cancels
the Callback.
Operation
With Callback, a user does not have to repeatedly call a busy extension back, hoping to fi nd it idle.
Leaving a Callback

[Super Display Soft Key]
[Keyset Soft Key]
To leave a Callback at a busy extension:
1.
Call the busy extension.
• Listen for busy or busy/ring tone.
2.

When the busy co-worker becomes free:
• You hear Intercom ring.

Answer the Intercom ring.
• The system automatically places a call to your co-worker.
• Speak to your co-worker when the call goes through.
