Introducing the Toll-Free Anonymizer Due to concerns of blowback from participants of the World Wide Wardial Project, I decided to make a "telephone condom" for those who wish to explore the depths of in-WATS. The Anonymizer is a very simple diverter service, which provides dialtone for placing US toll-free calls. What makes this service special is that every call is automatically placed with a completely random Caller*ID. The Anonymizer takes an exhaustive list of valid US npa-nxx pairs, and couples them with a random 4-digit subscriber number, to create a valid-looking Caller*ID associated with a random city somewhere in America. Only valid in-service exchanges from the 50 US states are used. This service combines a free DID from IPKall with Toll-Free termination from Alcazar Networks. Because of these free services, this system does not cost me anything to operate, and I invite anyone to use it, as much as you like. By using this system, you agree to obey all applicable laws. To use this service, simply dial: 1-425-606-3712 At the dialtone, enter your US toll-free number, including the country code (1): 1-8xx-nxx-xxxx Your anonymous call will then immediately connect. Once the dial-sequence has been completed, my server will remove itself from the data-stream by remotely bridging the SIP connections between IPKall and Alcazar, providing a crystal-clear call experience. If you have access to an Anonymous SIP client such as Ekiga, you can use this service by placing calls directly to my server, using a SIP URI such as: sip:18004444444@quickspoof.kb3tpa.pgh.pa.us This entire system is beautifully simplistic, and the pertinent parts of the source code are as follows: ; Toll-Free Anonymizerexten => 14256063712,1,Goto(tollfree,disa,1)exten => _1800NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1822NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1833NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1844NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1855NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1866NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1877NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1880NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1881NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1882NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1883NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1884NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1885NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1886NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1887NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1888NXXXXXX,1,Goto(tollfree,${EXTEN},1)exten => _1889NXXXXXX,1,Goto(tollfree,${EXTEN},1)[tollfree]exten => disa,1,Answer()exten => disa,n,DISA(no-password,tollfree)exten => _1NXXNXXXXXX,1,Set(CALLERID(all)=${CURL(http://quickspoof.kb3tpa.pgh.pa.us/api/random_cid.php)})exten => _1NXXNXXXXXX,n,Dial(SIP/${EXTEN}@tollfree.alcazarnetworks.com) The Random Caller*ID number is generated by a PHP script located at: http://quickspoof.kb3tpa.pgh.pa.us/api/random_cid.php The source code for this script is available at: http://quickspoof.kb3tpa.pgh.pa.us/api/random_cid.php.txt If you find this service useful, I would encourage you to contribute back to the community by adopting an exchange for the World Wide Wardial project.
