Often, he would happily whistle to himself as he listened to the recordings, and one day, the recording stopped abruptly as he was whistling. He discovered that he could dial recorded messages, and listen to all kinds of fascinating things. When talking on the phone, it didn’t matter that he was blind. It was around 1957, and Joe was eight years old. I can’t say for certain the exact moment when phone phreaking was created, but I can tell you that Joe Engressia’s experience was one of the first, if not the first. Unfortunately, the only way to find it is through a friendly phone company employee or your neighborhood phone phreak. When I was wiring a phone board in a building with 20+ phone lines, the ANAC number saved me a huge amount of time and trouble, and it saved a lot of calls to the operator, too. This number is not given out to customers, and is often changed every quarter, or even more frequently. When you dial it, an automated voice reads back the number you’re calling from. Telephone linemen use a telephone number called the ANAC (Automatic Number Announcement Circuit). Have you ever dealt with a poorly-wired building with multiple telephone lines? Figuring out which number you’re using can be quite a pain. Long before they were available commercially, phreakers were building controls that flashed lights when the phone rang.

A little later in this article, you’ll read about someone who went to jail just for possessing a device that could make free long-distance telephone calls.
No other type of hacking has generated the wealth of hardware gadgets (“boxes”) and massive underground community that phreaking has. They might mess with trunk lines just to see how things work (like when Steve Wozniak and John “Captain Crunch” Draper tried to call the Pope in Rome), or break into the telephone switches themselves, as Kevin Poulsen did when he rerouted lines to manipulate a radio station contest and win a Porsche. How could anyone who fits that description not be drawn by the allure of something as ubiquitous as the telephone? The phone on your wall is an amazingly simple device, yet the phone system on the other end of those wires is one of the most complex switching systems ever created.Ī whole class of hackers arose in the last half of the 1900s that focused their attention and fascination on the telephone system, and they called themselves phone phreaks. Hackers are people fascinated by technology and its applications.

This article is also available in PDF format. Either way, DO NOT TRY THIS AT HOME! Even if the boxes don’t work, many of them are still illegal. I doubt that any of it would still work today.
