CNAM

CNAM is an acronym which stands for Caller ID Name.

When phone calls are made, there are usually two user-facing identifiable pieces of information: a phone number and a Caller ID Name (usually a 15-character string). CNAM can be used to display the calling party's name alongside the phone number, to help users easily identify a caller.

There are numerous CNAM lookup services which allow you to pay a small fee to lookup the CNAM of a specified caller (by phone number).

Our goal is to make CNAM suck less. Join the cause!

http://www.reverseaustralia.com/developer/ - offers free lookups and spam caller information for Australian numbers.

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:


  • CallerID4u.com Calling Name (CNAM) Ready phone numbers are provisioned to receive “Calling Name” fees from a receiving carrier each time a call terminates on their platform. When this happens, Callerid4u’s Caller-ID name is retrieved and matched to a nationwide Caller ID database. These small fees are aggregated into monthly payments from which Callerid4u then pays you.

  • 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.

  • DipFees.com shares CNAM dip revenue, minimum U.S. termination of 400k calls / month. Customers have control over caller name and incoming calls can be picked up via sip.

  • StarcomPartners.com When you join Star Communication's CNAM Program, you can instantly add a monthly revenue stream to your business without changing your current telecom provider or day to day operations. Large Companies and organizations that make a large volume of outbound calls can benefit from our CNAM revenue program through revenue sharing. Many Telephone companies pay a small fee to the caller ID database providers each time they retrieve caller ID with name information for the end user. Minimum of 250,000 calls per month.

  • 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.
