Automatic Callback
When you reach a busy station, you can set Automatic Callback to have the system
monitor the busy extension and notify you when it becomes idle.
Automatic Callback can place you in queue for an available outside line, if you reach
a line group in which all lines are busy. When a station or line becomes available, the
system rings your telephone; when you answer the system automatically rings the
intended destination. The amount of time the system will wait for an idle destination is
set in system programming. Automatic Callback is also known as “CO Line
Queuing.”
³ To set Automatic Callback
1. If you hear busy tone after dialing an outside line access code or a station number,
press
Auto Callback or 4. Busy tone stops, followed by success tone, then busy
tone resumes.
2. Hang up. You can make other calls while waiting.
3. When the called station or outside line becomes idle, your telephone rings and you
will see a fast flashing LED.
• If you called a busy station, the extension LED flashes green (incoming call)
and the called number displays.
• If you called a busy outside line, the extension LED flashes green (incoming
call rate). The seized line’s number displays.
4. Answer within about three rings (can be programmed to ring up to three minutes)
to prevent the callback from being cancelled. After you answer, you hear success
tone, and the LED flashes green (in-use).
If you hear a busy tone after answering a callback, the called party is already on
another call or the line has already been seized or has received an incoming call.
Your request is not cancelled. You will be called again the next time a line becomes
idle.
If you were attempting to make an outside call, the telephone number is
automatically dialed, including the account code or override codes that were used.
