Callback

Conditions
Operation
54 ◆
When an extension user calls a co-worker that doesn't answer, they can leave a Callback request for
a return call. The user does not have to repeatedly call the unanswered extension back, hoping to
Þnd it idle.
The system processes Callback requests as follows:
1. Caller at extension A leaves a Callback at extension B.
Caller can place or answer additional calls in the mean time.
2. When extension B becomes idle, the system rings extension A. This is the Callback ring.
3. 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.
4. 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.
● Multiple Directory Number (virtual extension) keys do not support Call Waiting/Camp On
Programmable Function keys (code 35).
To place a Callback:
1. Call unavailable (busy or unanswered) extension.
2. Dial 2 or press Callback key (PGM 15-07 or SC 851: 35).
3. Hang up.
4. Lift handset when busy extension calls you back.
If the unavailable extension was unanswered (not busy), the Callback goes through
after your co-worker uses their phone for the Þrst time.
If you have Callback Automatic Answer, you automatically place a call to the formerly
busy extension when you lift the handset. If you don't have Callback Automatic Answer,
you must press the ringing line appearance to place the call.

1. At keyset, press idle CALL key and Dial 870.
