I'm not trying to start an aguement. I'm not even saying you're wrong. I'm simply questioning your findings. You said red boxing works these days, and that's true... But it all depends, as I explained ealier. You said that this "trick" works, and that's true... But only certain situations. You're making your findings out to be 100% fact. Trying to revive an old box isn't going to do much these days. Toll fruad is lame, anyway. =/
[edit] If you come across a carrier that is servicing an area that still relies on a toll center that pirmairly uses ACTS, good for you. There's a reason those are still around. The public switched telephone network (PSTN) has no set "standards", so to say, besides laws and FCC's. That's why a lot of these explotations in modern digital telephony are possible. Most switching systems weren't designed to handle such a level of flexability that the phone industry has adopted these days.
rbcp, what you're actually seeing is the calling party number (CPN) that the last switch is passing off to the terminated line. ANI is more handled by the switching facilities and ESS/SS7. This means that even if you're fowarding calls, everything is still nice and logged, just the way the g0v likes it
. Since 800 numbers are toll free, meaning you're the one paying the bills, you have the right to see who's calling you no matter what. I don't know why K7 displays CPN, or if that is even legal, but it's definitly a nice little trick. When I was getting prank called a few weeks ago by someone from the PLA (apparently, someone has been getting their hands on the telephone numbers of people who call into the bridge), they spoofed their CPN as well, so I was out of luck.
