Subject: Happy New Year! Message-ID: <20110101051544.GA11927@telecom.csail.mit.edu> Thank you all for your support and help in 2010. I appreciate your suggestions and kind words more than I can say, and I'm going to use your advice to improve this publication as much as I can in 2011. Here are my resolutions for the new year: 1. We'll have more information about VoIP and other non-traditional technologies. 2. I'll add more to our archives about the networks, technologies, and management of both the Bell System and of other companies. 3. I'll seek out and publish opinions from industry leaders. Happy New Year! Bill -- Bill Horne Moderator

The E911 database lists all these because the emergency responders need to know. The general public does not. There is a note in most phone books that the E911 PSAP will have all the informations about you, and if you want it not to be disclosed to them call the agency on its listed number, not 911.

I continually have to battle erroneous assumptions and misconceptions from the non-tech people I deal with in my various technology areas, and while it can be far easier to let people live with their bad ideas it is irresponsible (as well as career-threatening to me) if something that I knew needed attention was ignored just to avoid trying to set them straight (no matter how tough that can be - for various reasons). It may be convenient to pander to ignorance in technical matters, but does it really do anyone (except marketers) much good in the long run? Bah humbug I say, if us pedants can't keep a little of our domain intact in an area that demands accuracy for its basic function, where can we then go? :-) -- Regards, David.

Of course there is an authoritative answer. It comes from the database the network the call originated on contributes records to. Linking this with our recent discussion of Local Number Portability, this mess is an example of how things go wrong when information isn't managed neutrally. Also, there is an economic incentive to supply incorrect information on incoming calls. If the called party and the calling party are on two different networks, there is a charge to the inbound network to dip the database of a foreign network. To avoid this charge, the inbound network instead dips the database you described instead. On that database, records don't expire at times they should, like changing to another network per Local Number Portability, change of billing name, or disconnect then reconnect at a new service location with an unrelated subscriber. The incentive isn't "Supply accurate information," but "Supply something, anything at all." Now, one hopes that a telephone company, no matter how many subscribers it has, is capable of updating its own database with information about changes in billing name, disconnects, telephone numbers donated to Local Number Portability, and new connections/numbers received from LNP, even if foreign networks refuse to pay for the dip. But I know of instances in which a business's outbound trunks displayed CNAM of individuals (presumably the subscribers who once had those lines) when calling numbers belonging to the same telephone company. But the economic incentives are all wrong. Why should the called party's network be charged for CNAM? CNAM should be forwarded from the originating network for all calls as in enhancement to ANI. I think ANI is the correct model, not DNS. >- Since we were not the customer who saw the wrong name displayed, we > had to open a trouble ticket as a non-customer, which means the > far-end phone company could not verify who we were through an > account number and had to trust us to give the right CNAM.

I'm amazed that, as a nonsubscriber, you were even able to open a ticket. When I went through this with Comcast, the ticket had to be opened under the account of a Digital Voice subscriber. Of course, the correct solution to the error is to expire the record, which forces a new dip the database of the originating record. But these companies avoid paying for these dips like the plague, even though it's got to cost them more to perform their own data entry than the fraction of a cent the dip costs. >- CNAMs are only displayed by the recipient's landline phone company > (could be copper, fiber optic, cable TV or internet VoIP provider). > You can't test for correct CNAM by calling to a cell phone.

You will have no idea if a rural >independent in western Nebraska is dispalying the wrong name until >someone there complains to you. Overall, not a stellar system. Except that toll-free numbers CANNOT originate calls. A toll-free number either points to a group of inbound trunks or an ordinary phone line, which gives its own number in ANI. Outbound calls from a call center originate on outbound trunks with their own ANI. >***** Moderator's Note ***** >While there isn't a "root" LIDB database, the accuracy of the existing >ones could be dramatically improved by allowing them to copy some >items from the E911 database. . . . "Root" is the database of the originating network, where all such information should originate from. An E911 database is a third party, and shouldn't be used as source.
