FreeCNAM.org is providing a free CNAM API for Open Source PBX users.
This API queries a private CNAM database, and returns standard
15-Character CNAM results. Any entry not already in the database will
be queued for investigation, and added to the database as soon as
information is located. This system has access to several CNAM
backends, and is not a party to any use-limiting or no-caching
agreements.

The API is: http://freecnam.org/dip?q=2024561414

You can monitor the stats, including the current queue size, at freecnam.org

API Results will continually improve as the database grows, so please
be patient with limited results at this early stage.

  • BE WARY OF THIS ONE!

    If you click the link it comes up with a simple block Text Message
    “US GOVERNMENT”

    I doubt the US Government has any thing to do with it but… something is
    fishy here.

  • This is the main public Whitehouse switchboard number. I figured I
    would use a prominent phone number for my sample dip.

  • Well, that doesn’t make it very interesting: most calls I’d expect to
    get won’t have been seen by it before.

    I tried it, but it returns the same kind of junk that some of the databases
    do. For example, on a Florida number, it just says “FLORIDA” instead of
    the proper name (some of the CNAM databases have the right name).

  • The system uses real Telco CNAM Dips. Any generic names you get are
    from the subscriber’s carrier itself. We can only provide what we
    ourselves get.

  • So the question is, what is the angle?

    I have seen large scale outbound call centers make a nice sideline
    profit from CNAM lookups, you just have to hook up with the company
    that pays you the best share and make millions of calls after you set
    your CID to one of their numbers. Some give a generic opt out option.

    I have seen businesses built around just the take on CNAM dips from
    the telco. These operations only ring the phone long enough for a
    POTS line to grab CID info.

    I have used it not as primary income but because the outfit getting
    the kickbacks paid pretty well and the Opt out list was real, so they
    provided a service and they also provided a side revenue stream.

    Two extremes for sure. Both are taking advantage of the system. One
    in basically a rip-off and the second, as far as I am concerned, a
    valid revenue stream that helps offset operating costs of a true
    outbound call center.

    Is there some kind of money play here. Apologies for being a skeptic
    but so far only FreeSwitch didn’t have a hidden (some more than
    others) agenda. You know, dual licenses. People forced to sign over
    IP rights to get code committed to go into SwitchVox, not just Digium
    of course, that is just what popped to mind.

    Nothing leaps out at me, but I know for a fact that CID can equal big
    money. I am unsure of all the behind the scenes agreements on who
    gets paid and who pays.

    Can anyone elaborate? It seems like this would cost the developer in
    the beginning anyways.

    Again, skeptic, apologies if there is no harm, no foul. I just know
    that CID dips include money exchange. Just not sure how this would
    fit in.

  • Hi,

    The junk in CNAM databases like “FLORIDA”, “ONTARIO” etc. is IMO the
    carrier’s way to isolate their users and another excuse to charge more money
    for ‘the better plan’. In the end, it’s the carrier that inputs the info so
    if it shows “FLORIDA” with one database I can’t see how any other database
    would be different as the carrier is the only one that controls the outbound
    CID info. Calling me from POTS to snatch the CID will result in the same.

    …unless there were a user friendly CNAM service, where info could be
    updated by the end-user and queried freely by voip providers. I would update
    my cellular numbers for sure and know at least a dozen people that would do
    the same. Everyone is going VoIP so why not?

    Talking about ‘where’s the money or angle’… here is one, vanity. Charge
    $1/yr to a user per DID, if I don’t renew then delete it and re-query the
    original carrier.

  • I’ve been toying around with the idea of starting some kind of ‘Open
    CNAM’ project to destroy the current money hustle BS that dominates this
    industry. The ever-growing FreeCNAM database may be a good starting
    point for such a project.

    I would also like to use Bitcoin (BTC) as the micropayment solution for
    user-requested updates. Some nominal fee.

    If anyone wants to get involved, contact me.

  • If you can use curl, and can do some text parsing and know regular
    expressions, you may be able to use this free CNAM service:
    http://www.numberguru.com/ and integrate into your system. This one appears
    to have a more complete database. When I tried my number, I have gotten my
    full name, but when I use the FreeCNAM project below, I just get Florida.

  • Cool topic!

    Our company (generationD) developed some CID scripts for free use, and we would be interested in building and hosting this service.

    On the spec side, how do we avoid users claiming numbers belonging to others? (Could be an admin nightmare)
    Do we allow number ranges?
    Do we require caching, or limit lookups? (If not then this can get real expensive to host real fast)

    Just some ideas…

    Hi all,

    Let’s get some feedback going here and see if there is any general support in a user-driven CNAM concept.

    Assuming that your landline/mobile outbound provider does not push caller-name + number for you with your calling plan. Would you pay $1/yr to have the access to update your own personal CNAM info in a database that you can trust to be correct? One that 1000’s or even 100,000’s of other voip/pbx owners will use?
