- "Answering Machines: How to Crack Them"
-
-
- Ok, here's my first article for BAR. It's no big deal because I've done
- this a million times before so don't worry to much about getting caught.
- It's the easiest thing to find as many telephone answering machines as
- you want in any city you want. Just dial numbers at random when people
- are likely to be out and chances are you will get a machine. Many
- telephone answering machines with "beeperless remote" can be "cracked"
- fairly easily. They usually require a one, two, or three digit access
- code to activate the hidden features. These features include listening
- to messages that have been left by others, changing the outgoing message,
- rewinding the tape, and even eavesdroping on the room the machine is in.
-
- I will first describe how you would use various methods to cheat someone
- out of free telephone calls, if you were an unscrupulous telephone hacker
- (which, of course, we all are hehe)
-
- DISCLAIMER: I in all ways recommend the use of the techniques described in
- this paper, as they may be illegal. This information is for your
- INFORMATION and USE only.
-
- 1. If the access code is only one digit, the method is simple-try them all!
- To discover a two digit access code, you could try all pairs of digits
- (there are only 100 of them) but this means pressing 200 digits. Since
- extra digits are usually ignored, you can cut this in half and try all
- 100 codes with only 101 digits by using the following sequence:
-
- 01122334455667788991
- 35790246803692581471
- 59370494838272616051
- 72959628408529639974
- 197531864209876543210
-
-
- Some machines are restricted to only a few possible digits for the code.
- For example, if the digits must be 3, 5, or 6 as in some Panasonic models,
- you can use the sequence:
-
- 33556636653
-
- Of course, you stop as soon as the machine responds (Usually with a beep,
- the number of beeps indicating how many messages there are.)
-
- Three digit access codes are harder to "crack," but still you can try
- common sequences like 123 or all digits the same. Also, most machines
- with three digit access codes reset to a 000.
-
- Some 2 digit machines: Panasonic models KX-T1450, KX-T1460,KX-T1423
- Some 3 digit machines: Code-a-Phone models 2770, 5530, AT&T1330
-
- 2. Once you know the code for remote access, there is usually a one digit
- code for selecting a special function. For our Panasonic example, the
- one digit codes are as follows:
-
- 1 Backspace
- 2 Skip Forward
- 3 Reset
- 4 Memory Playback
- 5 Room Monitor
- 6 <Nothing>
- 7 Record Outgoing Message
- 8 <Nothing>
- 9 End Outgoing Message
- 0 Turn Off
- * Skip Outgoing Message
- # <Nothing>
-
- Even if the machine is turned off, you can activate it by calling and
- waiting for exactly 15 rings, then hang up.
-
- A little trial-and-error will usually get you a list like the one above.
- After a while, you may recognize the sound of the beep or tape rewind,
- or realize what machine you are talking to by guessing at only a few of
- the one digit codes. You can also go to your local electronics store
- and ask to see the instruction booklet of any of the models they carry.
-
- As another example, here is the list of commands for the Code-a-Phone
- model 2770:
-
- 1 Rewind
- 2 Repeat
- 3 Fast Forward
- 4 Change Outgoing Message (Press again to stop)
- 5 Stop Playback
- 6 Record Message
- 7 <Nothing>
- 8 Play NEW Messages
- 9 Turn Off
- 0 Time/Day Annoucement
- * <Nothing>
- # <Nothing>
-
- 3. Since you now know how to operate anyone's answering machine as if it
- were your own, let's see how you can "beat the system" using all this
- fancy technology. Let's say you live in Bangor, Maine and you have a
- friend in Yakima, Washington. You "crack" an answering machine in
- Yakima (or better yet, have your friend do it where the cracking is a
- local call). You change the outgoing message to the following:
-
- "Hello?...<LONG PAUSE>.... Yes, operator, I will accept.
- Hey, buddy, how are you?"
-
- Now you are all set to make a COLLECT call to the answering machine and
- IT WILL ACCEPT THE CHARGES! You can then leave a message as long as you
- want. When you are through, your friend calls the machine, gets the
- message, and can leave a message for you which you call back and hear
- COLLECT! When you are done, your friend calls up the machine, erases
- the messages and puts back something like the original outgoing message
- (or leaves it blank) and no one is any the wiser.
-
- If you use different machines and don't run up too big a bill on one
- phone number, it might not ever be noticed.
-
- You can signal your friend to call by ringing twice and hanging up,
- or placing a collect call from "Fred" which is refused, or simply by
- waiting until a pre-arranged time.
-
- You can also find a similar machine in your city, so your friend only
- has to call the answering machine collect and you do all the answering
- machine hacking. Long distance collect calls are safest when done from
- a pay phone.
-
- 4. A method that does not require making collect calls (and using an
- operator) is a little more complicated, but may work very well on
- some answering machines. The idea is to get the answering machine
- to make an OUTGOING CALL! Here's how to do it:
-
- First, "crack" a machine in your local area. Then, call up the machine
- and leave the following message:
-
- "Wait about a minute (make some noise in case the
- machine is a voice activated one.) Then dial in
- the number to be called (1-XXX-XXX-XXXX.) and
- let the tape run for about another minute like
- earlier. Then leave the message to your friend."
-
- After you have left a message as long as you want, hang up and call
- back. Enter the access code and the one digit command code for message
- playback. Wait for your message to start, then hang up!
-
- If you are lucky, the machine will keep playing its message into the
- phone, even though the connection is broken and eventually a new dial
- tone appears on the line. After the new dial tone is there, the digits
- you put in your message dial the phone, and after a few rings, your
- friend picks up the phone and hears the rest of your message.
-
- After enough time for the message to get there, call back and rewind
- the machine, "erasing" your message. For more safety, record a new
- nonsense message over the old one.
-
- Most "beeperless remote" answering machines will detect when you have
- hung up on them, but we suspect that some of them finish playing the
- message in progress before they turn off. Experimentation will show
- which ones can be used with this method.
-
- That's all folks...so enjoy and always keep an open line.
