- Hacking Voice Mail Systems
-
- Voice Mail is a relatively new concept and not much has been said about it.
- It is a very useful tool for the business person and the phreak. The way it
- works is that somebody wishing to get in touch with you calls a number,
- usually a 1-800, and punches in on his touch-pad your mailbox number and then
- he is able to leave a message for you. Business experts report that this
- almost totally eliminates telephone tag. When a person wishes to pick up his
- message all he needs to do is call the number enter a certain code and he can
- hear his messages, transfer them, and do other misc. mailbox utilities.
-
- Most VMSs are similar in the way they work. There are a few different ways
- the VMSs store the voice. One way is that the voice is recorded digitally and
- compressed and when heard it is reproduced back into the voice that recorded
- it. Another method that is slower and uses more space, but costs less, stores
- the voice on magnetic tape, the same type that is used to store data on a
- computer, and then runs the tape at a slow speed. Using this method the voice
- does not need to be reproduced in any way and will sound normal as long as the
- tape is running at a constant speed. On some of the newer VMSs the voice is
- digitally recorded and is transformed from the magnetic tape at about 2400
- bits per second.
-
- There are many different types and versions of voice mail systems. Some of
- the best and easiest to get on will be discussed.
-
- Centagram
-
- These are direct dial (you don't have to enter a box number). To get on one
- of these, first have a number to any box on the system. All of the other
- boxes will be on the same prefix; just start scanning them until you find one
- that has a message saying that person you are calling is not available. This
- usually means that the box has not been assigned to anybody yet. Before the
- nice lady's voice tells you to leave the message, hit #. You will then be
- prompted for your password. The password will usually be the same as the last
- four digits of the box's number or a simple number like 1000, 2000, etc. Once
- you get on, they are very user friendly and will prompt you with a menu of
- options. If you can't find any empty boxes or want to do more, you can hack
- but the system administrators box, which will usually be 9999 on the same
- prefix as the other boxes, will allow you to hear anybody's messages and
- create and delete boxes.
-
- Sperry Link
-
- These systems are very nice. They will usually be found on an 800 number.
- These are one of the hardest to get a box on because you must hack out a user
- ID (different from the person's box number) and a password. When it answers,
- if it says, "This is a Sperry Link voice station. Please enter your user ID,"
- you will have to start trying to find a valid user ID. On most Sperrys it
- will be a five digit number. If it answers and says, "This is an X answering
- service," you first have to hit *# to get the user number prompt. Once you
- get a valid user number will have to guess the password on most systems, it
- will be 4 digits. Once you get in, these are also very user friendly and have
- many different options available.
-
-
- RSVP
-
- This is probably one of the worst VMSs but it is by far the easiest to get
- yourself a box. When it answers you can hit * for a directory of the boxes on
- it (it will only hold 23). If you hit # you will be given a menu of options
- and when you choose an option you will then be prompted for your ID number.
- The ID number on an RSVP system will just about always be the same as the
- mailbox number, which are always only 2 digits.

- The Aspen voice message systems made by Octel Telecommunications is in my
- opinion the BEST VMS made. To get a box on an Aspen, you need to find an
- empty box. To find an empty box, scan the box numbers and if one says, "You
- entered XXXX. Please leave a message at the tone," then this is an empty box.
- You next just press # and when prompted for your box number enter the number
- of the empty box and friendly voice of the nice lady will guide you through
- all of the steps of setting up your box. She first tells you what you can do
- with the box and then will prompt you with, "Please enter the temporary
- password assigned to you by your system manager." This password will usually
- be 4 digits long and the same as the box number like 1000, etc. Once you get
- on their are many things you can do. You can make a distribution list where
- if you want to leave a certain message to more than one person, you can enter
- the list number and all of the boxes on the list will get the message. You can
- also have the system call you and notify you that you have new messages. These
- systems also have what they call "Information center mailboxes" that are
- listen only and can also have a password on them so the person calling has to
- enter the password before he hears the greeting message. Aspen VMSs have a
- system managers mailbox that will just about give you total control of the
- whole system and let you listen to people's mail, create and delete boxes, and
- many other things.
