I read of this several months ago and more recently read that Pacific Bell will be testing the new service in the San Fransisco area. Pacific Bell's plan sounds like the one I read about months ago; -There will be an additional charge for the feature plus the cost of buying the display unit. -There will be an addition charge/service for those who DON'T want THEIR number displayed on these devices. :-) If you can be patient for a couple of more years, my opinion is that you may then be able to get an answering machine with this feature. I've notice Pacific Bell on USENET before, maybe one of their users monitors this newsgroup and would be willing to provide more specifics. ------------------------------------------------------------------------------ Gordon Vickers 408/991-5370 (Sunnyvale,Ca); {mips|pyramid|philabs}!prls!gordon Every extinction, whether animal, mineral, or vegetable, hastens our own demise.

In some areas of the East Coast, you can now get ANI (automatic number identification) service by paying a service charge and buying a ~$40 box to display caller's number. As ISDN is installed (already available at many residences here in Phoenix), this service is automatic - part of the ISDN protocol includes the caller's number. There have been some privacy flames about this in the news media, so its possible that ANI will be outlawed.

Only if your local phone system supports this new service, and you're paying for it. If you take the device to an area which doesn't support it, it won't work. Very few areas will support it in the beginning. Standard voice phone service, at the moment, never sends the calling phone number to you, so it is inherently impossible for any device on your line to show it to you. -- Welcome to Mars!

I think they took place a couple of years ago. The device tested had the ability to display the telephone number of the incoming caller, "lock out" certain numbers from being able to call yours, and a couple others I can't remember.

One of the example is that Bell PA has temorarily suspended that experimental service.

Well, the local companies are starting to offer what here in NJ is called "Class Calling Service" -- part of which is a hack to identify the calling number [Caller*ID service]. It costs money and you need a decoder box to display the digits. The details on how the protocol works, I'm told, are available in various Bellcore technical bulletins: TR TSY 000030 -- customer premis data interface, or some such TR TSY 000031 -- calling number delivery TR TSY 000032 -- bulk calling number ID [?] These things are available from your nearest Bellcore but cost money, like $25 per TR or so. I am this close to stopping by the local office and picking them up, because we'll eventually have these services here too and I'm interested in building a decoder box for it [another Interesting Project for the list], but it's relatively low priority at this point, so I'm not sure when I'll get the chance to go get the TRs. Has anyone else gone out and fronted the bucks yet and can provide more details?? Rumor has it that it's done via a 212-modem-like signal between the first and second ring, but that's all I know about it. _H*

In article <1467@PSUECLB> was@psueclb.BITNET writes: > I have interest to buy an answering machine which has the >capability to display the incoming telephone number before I pick >up the phone receiver. There has been a debate in the New England area on whether to provide this service as part of a package. Yes, it's called tracing the call. On an old switching relay system, it's not trivial: Fike and Friend's "Undestanding Telephone Electronics" goes into some detail on the system. On the new computer switching systems, since there is some memory that remembers what phones are hooked to what bus lines, transmitting the number of the caller would be trivial with a well designed system. The problem is for confidential recipients, like suicide lines, and unlisted callers. Do you *really* want the suicide hotline to have your number if you call? Or to give out your unlisted number every time you call for pizza? -- Nico Garcia, Engineer, CIRL Mass. Eye and Ear Hospital raoul@eplunix

> The problem is for confidential recipients, like > suicide lines, and unlisted callers. Do you *really* want the > suicide hotline to have your number if you call? Or to give > out your unlisted number every time you call for pizza? Not everyone cares if other people know their phone number, and not everyone cares who is calling them. So give the caller a choice. If every phone had it's number, and an alternate id, and you gave the caller the choice on what to send, this should cover all bases: Send normal number: <area code> <xxx> <yyyy> Send id: <area code> <0XX> <YYYY> Send blank: <area code> <001> <0000> For phone solisitations, the caller may wish to leave a phone number, for return calls, or mearly the id. People can set their phones to screen all calls that are hidden or blanked, or to screen calls from all but select people. This would also add a possible additional security layer for phone in modems. Though how secure are the phone company computer? ID faking? Ghost phones? Another usefull thing about unique IDs: you can still register a complaint with the police of the phone company even if the other caller masks his call and send the "id". You don't know who it is but the phone company can find out. And finally, for people REALLY worried about being anonymous for calling in about taxes, drugs, or other things: There's always pay phones.
