If anyone is seriously interested in ANI SYSTEMS, (commonly known as
"Automated Number Identification", should contact Doc's House BBS, USA
FIRST QUESTION IS: What the heck is ANI??? Why should I know about it??
ANI is a "rumored" system to auto-trace any phone call from ANI-equipped
telephone systems. LET ME MAKE ONE POINT VERY CLEAR!!!!!!!!!!
.....................ANI is NO RUMOR GENTS!!!!!.........................
Let me begin by giving you some common examples of ANI systems presently
in operation not only in the US, but also in Canada and Europe:
1. 911 (emergency area service) is ANI. The second you call the system
can detect the calling number. Tied to a computerized database
consisting of phone company records of the address serviced and
the account name.....instant information as is passed to a
computer monitor for assistance in fire, police, medical crisis.
2. LD ANI credit card toll calling. If you have seen phones which take
credit cards where you can pass your "tape stripe" down the phone
......this is an ANI equipped system. It will automatically read
the credit card, report the calling number, number connected to,
the credit card, and the credit card company where multiple cards
are accepted
3. CO/411
Can you call your operator (usually 0 or 00), information (411),
or your local business office and have them tell that it is you
......or can they call you back without asking for your number??
If so, then the CO (Central Office) is providing ANI service to
the business offices.
HOW DOES IT OPERATE?????
ANI is a encrypted set of signals originating at your CO (exchange Central
Office) that passes in the signal thru all connections to the terminal pair
(the person you are calling). This signal is common on all ESS (electronic
switching systems) and has been around for years.
ONE POINT I WILL REITERATE....ANI HAS EXISTED FOR MANY YEARS!!!!!!!!!!!!!
The signal has always been around but was encrypted (thing of it like warp,
dms, ppak using a encryption password when you modem) so only telecomm
experts and phone company people knew it.
The signal floats all over the country so that telecos can track calls for
interco interstate LD revenue sharing on LD calls, monitoring, controlling
LD traffic, and many other tellco uses.
WHO HAS ANI CAPABILITY????
1. Obviously the telephone company
2. LAW ENFORCEMENT AGENCIES. It would stand to reason that if you have
911 or a telephone company with a security department that they
operate closely with the phone companies
3. "Audibon" This is a buzz work for the US Military communications
network which operates on bases, Supply Depots, and other installa-
tions where security of information and tracing is required.
4. GOVERNMENT AGENCIES- needless to say if we can send a man to the
moon, drop bombs down airshafts, and have other "high-tech" systems
you would not assume that the Secret Service, FBI, and other agencies
would not easily have the capability.
5. NOW THE KICKER.....
a. PUBLIC TELECO SERVICE - is being offered in test cases in New
Jersey and a few other locations for $ 3-4/month. That means
if you call these areas and the other party has signed for the
service they instantly have your number
b. "BLACK BOXES" - remember I said the "signature" passes from the
originator to all points as a part of the signal
(transmission or your telephone call). So anyone
having a "descrambler" can decipher this no matter
where they are or whether the local phone company
offers ANI service to the public.
c. CONSULTANTS/DEVELOPERS - obviously anyone who is involved in
telecommunications development, switch
technology, consulting, or other areas
would know of the technology and could
have ANI.
WHAT DOES IT LOOK LIKE??? CAN I TELL IF A CALL IS ANI detected????
NO.....to the later question you can not tell if your call was ANI
detected by the person you called. All they need do is to
decipher a code that was already in the line.
VARIES....basically looks like a little box with a display (LED/LCD)
which displays the number calling (including area code or
international where applicable).
The more sophisticated ANIs have a precision clock and a memory
to hold the exact date, time, length of call, number which called,
and other information for 10-100 units depending on the equipment.
WHAT ABOUT IF I AM INTERNATIONAL???? OR SAY AN OLD "STEPPER" OFFICE???
1. Old stepper type (rotary) is not ANI at the CO without very special
office adaptions....so chances are you are not automatically sending
ANI identification
2. INTERNATIONALLY.....this varies but generally the older systems will
not be ANI unless they meet one of the above
tests such as 911, credit card, etc.
HOWEVER>>>>>>>>THIS IS THE BIG HOWEVER SO PAY ATTENTION!!!!!!!!>>>>>>>>>
There is and "HAS BEEN" for a long time what I will call "reverse ANI".
People often shoot their mouths saying they can't be traced cause they are
in such-n-such a place, don't have ESS, or give me other lame explanations.
Well, you are TOTALLY WRONG!!!! We can reverse send an ANI IDENT!!!!
Just as most US phones automatically are now sending ANI codes, we can send
(add if you want to think of it that way) a reverse ident as phones are two-
way communications. This signal can be "encoded" as a SPECIAL TELECO ALERT
SEQUENCE. (For those that have flown this is like transponder squawking of
3300 or 7600....non-pilots that is a kidnap or highjack type situation).
Once "reverse-ANI" is initiated all stations are instantly alerted all the
way back to the originator. While it is true that perhaps then may not get
right to your individual phone instantly, within a few computer microseconds
then can get to any international system and call that system. Even those
system not yet totally equipped have ANI decoders and can trace a call in
a very few minutes by lookinf for the "fingerprint" of "reverse ANI ident"
on a particular trunk, cable, or pair (your phone)!!!!!
