AllFreeCalls.net is offering free international calls to select countries. All you have to do is call this Iowa phone number: (712) 858-8094, and then enter the usual 011 + Country Code + Phone Number. How do they make money? Via TechCrunch:
Iowa is apparently the only state taking advantage of an FCC kickback scheme that gives telco?s a portion of the fees generated from every inbound call to an Iowa number. So when you call the AllFreeCalls phone number, a portion of any long distance fees you are paying go to the company. The kickback is apparently authorized via the Universal Service Fund. These kickbacks are enough on average to more than cover the international outbound calling fees.
