Phone Dial Locks -- How to Beat'em Courtesy of the Jolly Roger
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~
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 b
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 possible 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!
