♦ Callback Number – If the previous option has been enabled, enter the
dial-in user's ISDN line number here.
♦ Check to enable Callback Budget Control – Enable the callback budget
control.
♦ Callback Budget (Unit: minutes) – By default, the callback function has
a 30-minute time restriction. The budget will be decreased automatically
per callback connection. Once the callback budget has been exhausted,
the callback mechanism will be disabled automatically.
