- This is a quick glossary of "caller ID" varieties, by Stanton McCandlish,
- mech@eff.org, Electronic Frontier Foundation Online Activist.
-
- CNI, CNID - Calling Number Identification. It's caller ID as we usually
- of it - the service individuals and businesses can buy from the
- telco; blockable by the caller usually with the code *67 on a
- per-call basis, and if you're lucky, even on a per-line
- permanent (but reversible) basis. The FCC has proposed, under
- pressure from commercial interests, to ban per-line blocking.
- CNID is not available in all areas, and is not fully compatible
- from one area to another.
-
- CID - Caller Identification; non-technical synonym of CNID.
-
- ANI - Automatic Number Identification - this is unblockable, and far more
- revealing - gives phone number, name, and address. It is a basic
- "feature" of all 800 numbers, and probably 900/976 numbers as well in
- the U.S., and cannot be blocked by the caller. It exists ostensibly
- to prevent fraud and to enable accurate billing, but is actually mostly
- used to collect personal information for commercial databases and
- mailing lists. ANI works no matter where you live in the US, and
- possibly in Canada as well. (???)
-
- AIN - Advanced Intelligent Network - rather vague and silly name for a
- caller-id type "service". Brock Meeks says of AIN: "Advanced
- Intelligent network is indeed used. At least, I used to run
- across it all the time when I was working for CommDaily, it's in
- conjunction with SS-7 services. hell, ask MCI about their AIN networks
- and how they've licensed that platform to the Canadians for "seamless"
- services between the two countries."
-
- CLI, CLID - Calling Line Identification; synonym of CNID.
-
- CPN, CPNI - Calling Party Number, Calling Party Number Identification.
- Synonymous with CLI & CNID.
-
- SS-7 - According to Brock Meeks of Communications Daily and CyberWire
- Dispatch, SS-7 [see AIN, above] is "not a 'service' but a
- *platform* on which Caller ID type services are built and delivered."
-
-
- These definitions are not very precise, and I don't make any warranty as
- to their perfect accuracy. - mech@eff.org
