Callback
The Callback feature allows you to place a Callback on a busy internal extension or an
extension that does not answer. The system automatically places the call when both
extensions are no longer busy.
• When another party has left a callback on your phone, the
softkey is
displayed in the menu.
• If a callback is left on a line other than your prime line, it will display only after you
select the line.
• Each extension can have 10 callbacks.
• Callbacks are returned on a first in/first out basis.
• If you try to leave a callback on an extension that has already received 10 callbacks,
you will hear a fast busy tone.
• If there is no answer when you return a callback, you may either hang up and cancel
the call or leave a callback on that extension.
• A callback that you place on another extension returns to your phone with a three-
ring system ring when both your phone and the called extension are on hook. That
call is automatically canceled if you do not answer within a system-defined time
period.
