Gizmo, do you say that because flaws don't exist like they used to, so, we're limited to lineman's sets?

sorcerer, it's always good to know how to hide your phone number and get free calls, and generally exploit the phone system in ways it wasn't intended to be used. it doesn't seem like much has changed from back in the old days, just that we can't use flaws in their routing systems (that I'm aware of) using simple electronics...or whistles.

I would think that would be considered hacking more than anything since everything is controlled by computers these days.
