AllFreeCalls.net offers free calls if you call a number in Iowa. As Techcrunch reports, the founder created his own telephone company in Iowa under an FCC kickback scheme that gives telephone companies a portion of the fees generated from every inbound call to an Iowa number. So, when you call them, a portion of the fees go to the company, and they use it to cover the international calling fees.

They offer service to Argentina, Australia, Belgium, Brazil (Rio De Janerio), Canada, China, Christmas & Coco’s Island, Cyprus, Denmark, France, Germany, Greece, Hungary, Ireland, Israel, Italy, Mexico, Netherlands, Norway, Poland (Warsaw), Portugal, Russia, Singapore, South Korea, Spain, Sweden, Switzerland, Thailand, UK and USA, with more coming soon.
