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.

• 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.

• 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.
