I think you may have something here.
You can leave the call through number on your out going message.
If that number is not keyed in before the end of the out going message,
the line is hung up.
Its like the "to bypass this message press 1" message.
If the tele-scum is not really listening to the out going messages anyway,
they will never hear
this by-pass number.
