usage. To enforce this budget, check the Enforced checkbox.
in Override mode. Checking this option allows you to exceed your budget during the current time period
without tearing down active connections. At the end of the current time period this option is automatically
deactivated. If you want to be able to exceed your enforced budget again, you must check this option for

Checking Override disables call blocking, even if the call is over its limit. The override flag is automatically
reset to be off at the start of a new period. This is so that you don't need to set Enforced to off to by-pass
the limit, and then forget to turn it back on when the new period starts.
