A while ago, we announced global free calls to toll-free numbers. 1800FREE411 is just one of them. When you call it, it helps you look up a U.S. person or business from their directory service and then connects the call (assuming the person or business is listed in directory, of course). And the directory service bears the cost of the call as it seems to be ad-supported. So you use SkypeOut to connect to the service, and the service to connect to the one you’re calling.
I’ll have to give this a try soon, too bad they don’t support the foreign country that matters (*cough*…Norway *cough*)
