Using Callback
When you direct a call you have answered to another telephone, the system
monitors the call to make sure it is answered. If no one answers the call within a set
length of time, the system directs it back to you.
Callback generates a variety of displays. Most occur after a set delay and are listed
in the index. Some occur immediately if the telephone to which you are directing a
call is out of service or otherwise unavailable. These are listed with the descriptions
of the specific features such as Transfer or Camp-on.
