Are there any plans for modems to capture caller ID? If so, what about the necessary commands for the computer to inquire what it is?

To the best of my knowledge, no major modem manufacturer has actually announced that they're going to support the Caller ID feature in their modems. Lots of folks are talking about it, but it appears that most are waiting to see how widespread the feature actually turns out to be and what the regulatory acceptance will be before investing much in the way of engineering. Caller ID uses a modulation scheme unlike any found in typical PC-class modems and also requires the ability to receive it without going off hook. Both of these require pretty significant changes in the modem; it's not trivial to support Caller ID in a modem. About the closest thing to a Caller ID "command" is what is contained in the Hayes ISDN AT Command Set. ISDN, as you may know, includes Caller ID as a built-in function. Our ISDN PC Adapter can deliver the information as part of the "RING" message, store it in a string register, or both. Any future modem implementation is likely to be similar, but no company has made any announcement to that affect as far as I know. -- Toby Nixon, Principal Engineer | Voice +1-404-449-8791 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.

That's ironic from a company that sells ISDN products. Caller-ID is widespread and I'm sure it will catch on much faster than ISDN, even if the latter will replace it in the long run. >Our ISDN PC Adapter can deliver the information as part >of the "RING" message, store it in a string register, or both.

So expand it a little, to make it *really* useful: the modem has a table of phone numbers to which it will auto-answer; all others it ignores. You can do the same thing in the host if you are a Big Site, but for little guys like my PDP-11 having the modem do it would be wonderful. It would be the best modem security feature to come along in ages. It would also mean I could leave the modem on-line on my regular house phone line, and not worry about it whistling at my mother. :-) <csg>

So expand it a little, to make it *really* useful: the modem has a table of phone numbers to which it will auto-answer; all others it ignores. You can Caller ID boxes are already being sold inexpensively. Hello Direct (1-800-HI-HELLO) has an AT & T unit, with an LCD display, for $59.95 This says that the price for a caller id board can potentially be much less. (Unless AT & T is artificially pricing them low ) A likely scenario is a standalone caller ID board that plugs into your pc bus, has 2 RJ11 jacks ; plug the telephone line into one of them, and plug the modem into the other. The board traps ringing until it picks up the caller id, wakes up a TSR to decide what to do, and either connects the incoming line to the outgoing jack, or lets it ring forever. So you can get the caller ID function without having to buy a new modem; you can use the 'filtered' output for your voice calls, fax, modem, or other purposes. As Toby says, people are probably waiting to see if the concept (caller ID) catches on. We're not making such a board ourselves :-) / Jon Sreekanth Assabet Valley Microsystems Fax and PC products 346 Lincoln St #722, Marlboro, MA 01752 508-562-0722 jon_sree@world.std.com

This would be a Really Good Thing except that even small sites usually have a news or mail neighbor that dials out from behind a PBX. The capability exists to have Caller ID pass a PBX extension, but in reality, you get the number of the trunk via which the call arrived. Therefore, the valid number table would have to know about all the trunks in the PBX's outgoing trunk group. Nasty. (There was much talk of this some time ago centered around the idea of using Caller ID to screen out calls from telemarketers. See the telecom-privacy [*not* comp.dcom.telecom!] mailing list for current discussion.) -Ed

My understanding is that it is possible to have an outgoing trunk group set up to ANI/Caller-ID to a single number -- that is, for Caller-ID purposes, they'd all display the same number, which could be the main INCOMING number of the company. Certainly makes a lot more sense than having it ID as a number that you can't even call back! -- Toby Nixon, Principal Engineer | Voice +1-404-449-8791 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.

The number you receive is sometimes the main inbound number, sometimes a fictitious 'billing number' which you cannot call back, sometimes the actual trunk number of the outbound trunk (sometimes you can call it and reach the PBX attendant, sometimes no answer), and sometimes the actual extension number (if the caller is using Centrex). What it comes down to is that with Caller*ID, there are lots of options, and you can't design a system that expects only one of them to work. Also, at least for the present time, any call from outside your LATA is displayed only as "OUT OF AREA". -- Dave Levenson Internet: dave@westmark.com Westmark, Inc.

I recently saw an advertisement about a PC-based call mgmt package. This package included a small database, a TSR monitor, and a little box that attached to the serial port of your PC. The little box looks like a simple RS232C to RJ11 adapter, but looked like it had a little circut board to decode the caller ID. You hooked it to your phone with a provided Y connector. Phone jack -> [+]-----------+----------------- Voice Line | | | /-+ +-------[ | RS232C \-+ When a call is received, the CallerID decoder would decode the signal into what I assume would be ASCII. The TSR would read this as incomming data, compare the number against the database, and pop up a "note card" data screen about your caller. What I want to know, does anyone know where just the CallerID decoder can be purchased, and for how much? If you could purchase the decoder, you could wrtie a TSR to monitor the RS232C port, and check the incomming number against a database of numbers, and if the number is in the database, send an auto-answer code to the modem.
