A friend had one up in Buffalo. We checked out the various costs. It turned out that getting a Foreign Exchange line from our building to Newark, NJ, would have let my GF and I talk using an untimed local call, and let him and his... make a long distance interstate call. The call pricing was so much better that we were seriously considering getting that FX circuit. Afraid I no longer remember the cost structure, but if we'd have stayed there longer, and if our relationships had continued, we might have gone for it. Well, at least until Execunet came out... -- _____________________________________________________ Knowledge may be power, but communications is the key dannyb@panix.com [to foil spammers, my address has been double rot-13 encoded]

I remember the year I spent in Chicago, academic year 1964-5, seeing adverts for reduced-price calls within Illinois: services would route calls through switches they controlled in CA or GA or NY, charge the r/t tariff plus a service fee, and come in well under the in-state tariff for such in-state calls.

I presume you are talking about dialed direct station-to-station rates. In those days rates were usually in steps broken down by mileage. Could you provide a rate step schedule for a year that reflects those high figures for California and Illinois? At $3/minute, a three minute call would cost $9.00. FWIW, Pennsylvania's rates mirroed AT&T rates. New Jersey was less. > It was cheaper to call Los Angeles from Chicago, than it was to call > Springfield. Or even Urbana. MUCH cheaper.

For once, you presume correctly. The bleep-bleep '3 minute initial rate' that was charged the instant somebody answered the call, could make a one-minute duration call -very- expensive. >> It was cheaper to call Los Angeles from Chicago, than it was to call >> Springfield. Or even Urbana. MUCH cheaper. (Latter part of the 1970s, >> Chicago to L.A. was 10c/minute after the first 3 minutes; Calling from >> one edge of the Chicago LATA to the far edge could be over 30c/min. I >> don't have figures handy for any INTER-lata/IN-state calls.) > >30c/ minute isn't $3.00 a minute. 'No #$*&, Sherlock" applies. FIRST, It was a call 'across the county', not to the far end of the state (which, being more than 10 times the distance 'as the crow flies', was much more expensive). The numbers I cited were for two calls I made with some regularity, "back when", and for which I remember the costs. SECOND, those rates I quoted were after AT&T LD rates had plummeted, and were strictly for showing that in-state rates were rapaciously higher than inter-state ones. What you think you know about INTER-state rates is irrelevant to INTRA-state rates, as demonstrated by an intra-state, intra-LATA rate more than 3x higher than an inter-state rate, for roughly 0.2% of the distance. Call it FIVE HUNDRED times higher 'per mile'. ***** Moderator's Note ***** Gentlemen, That's enough. Bill Horne Moderator

This is correct only as long as the feds require any carrier that receives Caller-ID via SS7 from an earlier carrier to pass it along unchanged. But what I would like to see is an agreement among phone companies to be ethical, defined as follows. 1) An ethical telco does not pass along any Caller-ID from a call originating on its network (at least not without flagging it as "unreliable" in some machine readable way) unless it can authenticate that the number belongs to the originating subscriber. 2) Similarly, an ethical telco does not (uncritically) pass along Caller-ID it receives from another carrier unless that carrier is known to be ethical also. 3) If an ethical telco receives a large number of complaints that one of its subscribers placed unwanted calls, and technical records show that the calls did take place, the telco will disconnect the subscriber and share his identity with the other ethical telcos and the public in a blacklist. Allow this type of cooperation to take place (and let telcos write contracts giving subscribers the right to demand it) and regulation on the subject would no longer be necessary. Best of all, the marketers would still be allowed to have phone service, but the majority who don't want their calls would be effectively protected. Let the law ban any circumvention of the filters as it now (too broadly) bans the circumvention of "DRM" technology.

False to fact. Unfortunately. >But what I would like to see is an agreement among phone companies to be >ethical, defined as follows. You ... overlook several critical facts:
  1. There is no financial incentive for any telco to enter into any such agreement.
  2. Spending the money to do the authentication, does not bring in any additional revenues. Unless it is a required function, this is against the best interests of the stockholders.
  3. There can be no significant penalty if telco signs your 'ethical' contract, and reneges on the terms.

This is 'theoretically' possible. But the cost is very definitely non-trivial It involves adding a database dip to the processing of every incoming call, (where there currently aren't _any_) and creating/maintaining the database itself. > 3) If an ethical telco receives a large number of complaints that > one of its subscribers placed unwanted calls, and technical > records show that the calls did take place, the telco will > disconnect the subscriber and share his identity with the other > ethical telcos and the public in a blacklist. Unfortunately, with the current state of the law. This is simply NOT LEGALLY POSSIBLE. To -make- it possible, one would, FIRST, have to have a law that makes providing 'false' CID info a criminal action, and SECOND, have a criminal conviction for that violation before the common carrier can terminate service to that party. One of the -fundamental- aspects of 'common carrier' law is that a common carrier is required to provide service to ANYONE who can pay for it, unless they are using it for criminal activities. This is something that requires government regulation -- along the lines I described -- to accomplish. There are no viable alternatives.
