Callback
If a System 25 extension or outside line is busy when you place a
call, you can request a callback. Your call will wait in a line
(called a queue) for the extension or line to become available.
The system will then alert you with a priority ring and complete
the call.
For inside calls, use Callback when you hear a busy tone or a
special ringback tone. For outside calls, use Callback only when
you hear fast busy tone.
NOTE:
You may hear the callback request queueing tone
automatically when you place certain calls.
