Currently we have two incoming lines, the second of which has call waiting, and a data line that is shared by a fax machine and a modem. We are currently not able to handle the phone traffic and the boss would like an automated solution rather than hiring a receptionist to answer the calls. We are interested in call routing to one of several phones and voice mail. A PC based PBX would be great! Basically, we would like the phone system to greet the caller and ask him or her for an extension number. The system would then route the call based on the touch-tones entered. The budget for this system is $5000 or less. Does anyone have any suggestions on how to do this or where I might find more information? Thanks in advance.

The Editor noted that this was done to make it easier to dial the most widely used codes (i.e. larger cities, centers of commerce, etc.) on the old rotary dial sets. Another story that I had heard was that AT&T had somehow concluded that people made fewer dialing mistakes when the codes were staggered across the country versus a smooth logical pattern like the ZIP codes. The staggered pattern was supposed to force people to pay attention to their dialing. (Of course, it doesn't work, as I've dialed a few wrong long-distance numbers myself.) At any rate, the continuity of a pattern like that would have been interrupted sooner or later with the introduction of new codes. BTW, am I by chance the only one who hates the newer X1X and X0X local prefixes? I always get them confused with area codes when taking messages or calling them. ------------------------------ Date: Tue, 22 Feb 94 17:15:58 EST From: Carl Moore Subject: Re: Area Code Closeness Flaw: 713 includes Houston, not Fort Worth.

Sounds unlikely. If you're going to use this definition, there are no "all digital" cells in commercial operation; there are merely cells which have some channels dedicated to digital traffic and some which are dedicated to analog traffic. Of course, if you're using Northern Telecom equipment, the point is moot because channels can be assigned to analog or digital traffic on a per-call basis. :-) David Boettger boettger@bnr.ca ------------------------------ From: Christopher.Vance@adfa.oz.au (CJS Vance) Subject: Re: 200 "Exchange" Within 1-900 Numbers Organization: University College, ADFA Canberra, Australia Date: Wed, 23 Feb 1994 00:00:41 GMT In article johnl@iecc.com (John R Levine) writes: >> is for instance 1-900-000-0000 available? > Probably not.

Maybe these phones only supported 666 channels? By checking the station class mark you can tell if your phone has extended channel capability (832 channels). The Motorola 8000-D sounds pretty old and may only support 666 channels. If the SCM is 00 to 07, then it only has 666 channels, if it's 08 to 15, then its 832 channels.

The larger pizza chains here collect ANI data and use a database. They usually ask if you want the same order as last time, etc., and often call back and verify if you are a first-time customer. The places not using ANI (caller-ID was just approved here and not yet implemented) ask for your number and call back to verify. You don't want to provide your number, that's fine, come in and use the counter service. It's not only the practical joke / unwanted pizza problem -- there's also the crime situation. Orders need to be verified as legitimate so they know they won't be sending delivery people to vacant houses to be robbed by someone in the bushes. True, you could still do that, but at least they would have a number where you were at one time, a clue of sorts. puma@netcom.com ------------------------------ From: William H.

Bill Glass [TELECOM Digest Editor's Note: This is true, it is ... or whether one should clean out the bathtub after one is finished using it or *before* one gets into it. Years ago when we had boarding houses with a common bathroom for all residents that was a subject of concern: what do you do about people who won't clean up the bathroom after they have used it, forcing the next person to have to clean it *before* he can use it? His sense of scruples tells him to clean it up after he is finished also, but that way he gets stuck cleaning it twice. Likewise, some residents would always manage to use all the paper and never bother to leave a new roll, forcing the next person to begin the process by rushing off to look for some. Courtesy is no longer the default as it once was in the USA. So many times now, we are forced into behaving like the people we dislike only from a sense of survival. We can either do things right (and do them twice as we adjust for what others are lacking) or we can get on the bandwagon with all the other fools. Years ago we used to expect the best from people; now it seems we expect the worst from people, and often that is what we get.

That's because the rate system is not designed to reflect costs, or even to promote "economically rational" behavior in some grand collectivist fashion, but rather to provide ways that business and high-volume residential users can subsidize low-volume residential users. (Most voters are low-volume residential users.) This is known as "Keeping Grandma's phone bill down." Since tone dialing is "new" and since Grandma doesn't have a tone-dial phone, tone dialing is extra.

As a matter of fact, not even the local telco operator can resolve the correct number in this circumstance. Last week, here in 314-land, at the government office building where I work, we had what turned out to be a "database error" in the PBX servicing us, which made a lot of the local phone numbers in St. Louis, including my home number, appear to be "busy" when we tried to call them. (It was a fast busy instead of a regular busy, so I suspected an internal problem, which is what it turned out to be.) While diagnosing the bug, I tried going thru the local SW Bell operator and, when I told her I was calling from a number in the 331 exchange, she said "No, you're not." Luckily, from TELECOM Digest experience, I knew what the problem was, and asked her, "You're showing 421-XXXX, right?" She said "Yes" and I told her that it was the billing number. She accepted that and tried dialing a couple numbers for me. (The problem got fixed shortly afterwards.) I would think this would cause a problem for the telco. It sure sounds like a security hole when it comes to tracing annoying or threatening calls. Identifying a culprit within a really big organization if someone is using one of its phones to make such calls could be nearly impossible. Will digital telephony change this, perhaps by forcing any PBX connected to the telco after some future date pass the real calling number on to the telco switch via some side-channel digital pathway? Or is this situation an un-correctable arrangement mandated by deregulation? Will [TELECOM Digest Editor's Note: Do government bureaucrats make obscene phone calls?

Surely the DTMF tones are just transmitted as any other sound on the voice channel? Here in NZ, well over 99.x percent of lines are connected to NEC NEAX 61 series electronic switches, and most of all the other older switches are DTMF capable.

The *big* difference is that people will no longer be able to easily tell what you encypted and what you haven't. Am coming to the conclusion that the "debate" is not about technical considerations at all, it is about power and money. The fact is that if the government can deliver Clipper phones for a $25 surcharge and Capstone modems/ethernet cards for $75, they will have filled a void (and in a year, if anyone else had an equivalent product, it should be available by now). Heard the same yammerheads bleating about Caller-ID but it is *very* effective in keeping unwanteds off dial-ups and can limit the need for tokens to the truely mobile. Like what the government has promised with C/C, for the authorized users it is invisible but a solid layer of protection (I do not trust *anything* 100%) against intrusion. I just want some to play with. *Then* I'll make a technical assessment. Warmly, Padgett [TELECOM Digest Editor's Note: It is like the 'war on drugs' and the jerry-rigging of the phones to not accept coins or have rotary dials.
