Quiet Termination lines are a type of test line used by the telephone company to test call routing. However here are some ways which either directly or indirectly have served the purpose of phreaks in the recent times. There hasn’t been much speculation about the new trends and methods of phone phreaking. Then you would get credited the time allotted for a quarter, nickel or dime, without even paying a trifle. And on hearing this sound the operator would know what coin you had just put in the phone. In the older times, they used to have a 3-coin payphone: when you put a nickel the sound was ding when you put a dime, the sound was of ding-ding and when you put a quarter, the sound which came was like gong.

These were similar boxes which were used to make free calls from payphones.Īll they used to do was to emulate or mimick the sound that the operator hears when you drop in a coin, without actually dropping the coin in the phone. Somehow, John Draper discovered that the toy whistle just happened to produce a perfect 2600Hz tone and so when he was transferred to England with his Air Force Unit he would receive calls from his friends and make them free for them by blowing his Cap'n crunch whistle into his end. In the 1960s, there was a breakfast cereal known as Cap'n Crunch which offered a toy-whistle] prize in every box of the cereal. He discovered that by sending a tone of 2600Hz over the telephone lines of AT&T, it was possible to make free calls. The Blue Box was invented by John Draper who was also known as Captain Crunch in early 60s. Being the first box in history, it was the one which started the whole phreaking scene. Party Lines were the numbers which were like numbers of a radio station that is … busy numbers.In these numbers, you could actually talk between the busy beeps, and could give information to one another … though it wasn’t much preferred because it was a hard thing listening between the beeps. So, if somebody called the 0045 at the time when you were on the 0044 call, both of you could get connected and could talk whatever you want, for as much time you wanted, absolutely free. They were numbers which on calling produced a 1000 Hz tone which was interrupted every 10 seconds.
Loop Around numbers were numbers which began with 0044 or 0045. But at the same time, you are listening to the audio because audio can travel through that 2.7K resistor to the phone. It makes you receive the call from the person who is calling you absolutely free…that means he won’t be charged anything.īecause you are not picking up the phone. Because of this, there wouldn’t be enough current to cause the telephone to be disconnected, and hence the billing equipment wouldn’t get triggered.

What the Mute Box generally did was that it used to take a 2.7 kilohms resistor in series with the phone line, so that when the call came in, you had a little button that you pushed really fast and that would stop the ringing tone but would still leave the connection open. The old Mute BoxĪ Mute Box was an electronic device which was used to receive long distance calls without being detected. There are a lot of methods which were used and we will talk about them in detail as we move on in the article. MethodsĪ lot of methods were used in phone phreaking but most of the older methods are no longer practical, the simple reason being the transformation of telephone lines from hand-worked job to digitised working.
Though there may be incidents which occurred prior to this, but this was the first reported incident about phone phreaks. Though nothing specifically is known about its origins, it is supposedly thought that the art of hacking telephone network had been in practice since 1960’s by a group of people who were caught making long distance calls. They may also be normal guys who have got exceptionally good hearing power and just by hearing the clicks, pops and whistle, they can do stuffs that we can’t. Who are phone phreaks?Ī phone phreak is generally a blind person whose life basically depends upon the sound he hears. Phreaking as we know it, is defined as playing, experimenting and exploiting the telephone network. The article presented here is about the various methods of phone phreaking as one of the early manifestations of hacking into systems.
