When an extension user calls a co-worker that does not answer or is busy, they can leave a Callback

request for a return call. The user does not have to repeatedly call the unanswered extension back,

hoping to find it idle.

The system processes Callback requests as follows:

Caller at extension A leaves a Callback at extension B.

Caller can place or answer additional calls in the meantime.

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 or unanswered)

extension B.

If caller A does not 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.

Callback Automatic Answer determines how an extension user answers the Callback ring. When

Callback Automatic Answer is enabled, a user answers the Callback ring when they lift the handset.

When Callback Automatic Answer is disabled, the user must press the ringing line appearance to

answer the Callback ring.

• An extension can leave only one Callback request at a time.

• Call Arrival(CAR) Key (virtual extension) keys do not support Call Waiting/Camp-On Programmable

Function keys (code 35).

• If an extension user initiates a Callback but does not hang up, their extension Camps-On to the

busy extension.

• Function Keys simplify Callback operation.
