A CNAM database contains calling party names to be used when identifying a calling party.

CNAM Lookup Services List:

www.VoIPCNAM.com offers CNAM lookup services to individuals and small businesses at economical prices. The service integrates easily with your existing Asterisk dialplan using the provided one-line examples. Rates start at $2/month including 25 lookups, and $0.02 per additional lookup.

http://www.squire-technologies.co.uk/products/CNAM.html

www.cnam.info offers both CNAM and a pseudo-CNAM service at a fraction of the cost. Integration with asterisk is as easy as downloading the AGI and adding a single line to your dial plan.


got-name.com - I am currently testing this service with an Asterisk PBX and it is working well. I also modified my callerid_shell.agi script to use their service after trying the sqlite database, google and anywho.

http://wholesale.metrostat.net - Provides real CNAM service to asterisk, openser and freeswith with simple http based API. No monthly fee just small deposit. Flat rate CNAM $0.018 per Query. Online access to your CNAM requests in realtime. Setup your account online instantly, CDR tool onine, add auth ip's and users online.

Add:

lookup_gotname() {
       out=""
       out=`/usr/bin/curl -s -m 2 -A Mozilla/4.0 http://cnam.got-name.com/?auth=<USERNAME>:<PASSWORD>\&type=http\&number=${1}`
       echo $out;
}

And:
lookup_order="sqlite3 anywho gotname google nanpa"
And:
                      411)
                               lu_name=`lookup_411 "${2}"`
                       ;;
                       gotname)
                               lu_name=`lookup_gotname "${2}"`
                       ;;
                       google)
                               lu_name=`lookup_google "${2}"`
                       ;;


An optional change: I (netplex/andrew) changed the lookup to not return the "NO AUTH" message because I wanted it to continue with other methods:
lookup_gotname () {
       out=""
       out=`/usr/bin/curl -s -m 2 -A Mozilla/4.0 http://cnam.got-name.com/?auth=USERNAME:PASSWORD\&type=http\&number=${1}`
       if  "${out}" = "NO AUTH"  ; then
               out=""
       fi
       echo $out
}


Commercial Blurb put in by Rehan:


CNAM is the caller ID on a call that is sent from a wholesale carrier.

The company that own's that DID number gets the INTERCONNECT income because it owns the number.

Companies who provide calling card and call centers don't care what is the caller ID (what is sent to the CUSTOMER when a call is made). Because of the non-concern, they can use a DID number from a carrier that is willing to share its CABS income. This way they make MORE MONEY and get some money back which they currently pay to the termination company.

For example, say you make a call using the calling card, but when your call goes through, the number will appear 1-212-6552222.

You being the calling card company or any other company has a lot of outgoing traffic.


Companies that share Cabs revenue:

• DIDX.org provides its wholesale members with DID's that pay up to .002 cent a min for sending the CABS. If you have 10,000,00+ terminating mins a month, DIDX can get this money to your pocket.

• ViaTalk White now provides an API for CNAM lookup. Haven't used it yet, but I've had decent luck with ViaTalk's other tools.
