[asterisk-users] Free CNAM

Thu Jun 2 20:15:16 CDT 2011

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?

I just checked several of my numbers and several others known to me, it really isn't much better
2 of them returned names other than mine, and all had the wrong city, though at least the state was correct.
All but one also had the wrong carrier.
I fear these databases are are so full of errors that they are mostly worthless.

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.

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.

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.
