I don't know of any telco that vets them. Technically, this isn't that different from the way some people used to commit DDOS attacks against large parts of the Internet - simply by sending lots of network packets with random numbers where the From: IP address is supposed to go. Today this technique no longer works in most of the world, because your Internet provider checks that the packets your computer sends to it are "from" IP numbers registered as belonging to you or to itself. If too many aren't, the provider disables your account and tells you why. All telcos technically can, and ought to, similarly vet the numbers in Caller ID strings their PBX-owning subscribers send. But as long as the only effect of junk calls on telcos' bottom line is as paying traffic, the telcos will continue enabling the spammers and frustrating any tech that would help you block their calls. All this would be grounds for a well-deserved class action lawsuit, but apparently AT&T now has an unbreakable defense against those, too. Darn!

Reports Cyberattack Led to 'Very Major Breach' Message-ID: <p06240820ca19f3256277@[]> I.M.F. Reports Cyberattack Led to 'Very Major Breach' By DAVID E. SANGER and JOHN MARKOFF June 11, 2011 WASHINGTON - The International Monetary Fund, still struggling to find a new leader after the arrest of its managing director last month in New York, was hit recently by what computer experts describe as a large and sophisticated cyberattack whose dimensions are still unknown. The fund, which manages financial crises around the world and is the repository of highly confidential information about the fiscal condition of many nations, told its staff and its board of directors about the attack on Wednesday. But it did not make a public announcement. Several senior officials with knowledge of the attack said it was both sophisticated and serious. "This was a very major breach," said one official, who said that it had occurred over the last several months, even before Dominique Strauss-Kahn, the French politician who ran the fund, was arrested on charges of sexually assaulting a chamber maid in a New York hotel. ... http://www.nytimes.com/2011/06/12/world/12imf.html

Subject: Hackers and thieves a growing Web menace / Technology lag leaves systems vulnerable Message-ID: <p06240834ca1a9e2930fb@[]> Hackers and thieves a growing Web menace Technology lag leaves systems vulnerable By Hiawatha Bray Globe Staff / June 11, 2011 On the Internet, there's nowhere left to hide. Around the world, computer networks are getting more vulnerable even as they grow more sophisticated. They are being penetrated and looted by digital intruders. The personal records of 100 million people were stolen in an attack on Sony Corp.'s video game networks. Up to 210,000 unemployed Massachusetts residents were put at risk by data theft software that infected computers at the state's Executive Office of Labor and Workforce Development. And in March, criminals stole vital information from Bedford data protection company RSA Security, a division of Hopkinton storage giant EMC Corp. The stolen RSA data was later used in a hacker raid on defense contractor Lock heed Martin Corp., an RSA client. The list of data breaches grows almost daily, and while consumers and businesses can take steps to reduce the risk of losing sensitive information, security analysts say that making our computer networks truly secure is virtually impossible. ... http://www.boston.com/business/personalfinance/articles/2011/06/11/hackers_thieves_run_wild_on_internet/

You missed the whole point of the original Boston.com article. Going to Dish or DirecTV is simply a switch from one retailer to another. The point of the article (and my post a few hours after yours) is to point out the effect of monopoly situation at the WHOLESALE level. If Walmart wants to sell TV sets or cabbages or shoes at retail, it can choose among wholesalers, and negotiate prices based on its market power in the retail marketplace. It can use its market power to force wholesalers to compete for its business. Furthermore, it can choose to purchase, or not purchase, other products from the same wholesalers. Walmart's competitors are free to make the same choices. But if Comcast wants to sell (carry) the signal of WFXT (the Fox affiliate in the Boston DMA), at retail, it has one choice: News Corporation. News Corp has the market power to demand whatever it wishes. It has the power to force Comcast to carry, and pay for, other News Corp products such as FX, Fox News, Fox Sports, and WZMY-TV (the MyNetworkTV affiliate in the Boston DMA) as part of the deal. The fact that Comcast has competitors (Dish and DirecTV) increases News Corp's market power. And, of course, Dish and DirecTV face the same situation in their negotiations with News Corp. >***** Moderator's Note ***** > > If it doesn't happen for others, they get to bear the consequences. You have > your own choice. What choice? WFXT from Comcast, WFXT from Dish, or WFXT from DirecTV? No matter which you choose, News Corp still gets its pound of flesh. Now I realize, of course, that you could receive WFXT off the air for free and without being forced to pay for Fox News, Fox Sports, Fox Whatever. Good for you! But be sure to thank all those Comcast, Dish, and DirecTV subscribers that are subsidizing you. That's why it's called "consumer protection"! Neal McLain ***** Moderator's Note ***** "What choice?"? The choice to not watch it, of course. I've written about the evils of television in this and other forums, and my views haven't changed. If you want to believe that the Tall White Guy should make all the decisions, that's your choice. I don't care what WFXT-TV broadcasts, or what Comcrap pays to relay the ooze from one screen to another, because I don't watch it. Bill Horne Moderator

Order a T-1 from the telco. You send the telco the audio and the signalling information in digital format. That includes the CID. The ANI is determined by the telco itself; they don't want anyone spoofing that and not getting billed properly. But the CID is determined by the originator. >The caller ID info is injected during the space between the first and >second rings - right?

No. But if you're originating the call from a PBX or from a VoIP gateway, you can tell the exchange what the data are. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."
