Phone Dial Locks -- How to Beat'em courtesy of Exodus


Have you ever been in an office or somewhere and wanted to make a free phone

call but some asshole put a lock on the phone to prevent out-going calls? Fret

no more phellow phreake, for every system can be beaten with a little knowledge!

 

There are two ways to beat this obstacle, first pick the lock, I don't have

the time to teach locksmithing so we go to the second method which takes

advantage of telephone electronics.

 

To be as simple as possibnle when you pick up the phone you complete a

circuit known as a local loop. When you hang up you break the circuit. When

you dial (pulse) it also breaks the circuit but not long enough to hang up! So

you can "Push-dial." To do this you >>> RAPIDLY <<< depress the switchhook.

For example, to dial an operator (and then give her the number you want to call)

>>> RAPIDLY <<< & >>> EVENLY <<< depress the switchhook 10 times. To dial

634-1268, depress 6 X'S pause, then 3 X'S, pause, then 4X'S, etc. It takes a

little practice but you'll get the hang of it. Try practicing with your own #

so you'll get a busy tone when right. It'll also work on touch-tone(tm) since

a DTMF line will also accept pulse. Also, never depress the switchhook for

more than a second or it'll hang up!

 

Finally, remember that you have just as much right to that phone as the

asshole who put the lock on it!
