Free International Phone Calls

This might be stretching the confines of the blog, but I recently came across this article in the New York Times. Realizing that many of us travel extensively and have family and friends in all parts of the world, I thought you might be interested in a way to get a free international 10 minute phone call. I tried it out last week with my wife who was in Guadalajara, Mexico until yesterday, and it worked fine. http://pogue.blogs.nytimes.com/2011/01/04/free-phone-calls/?scp=1&sq=freephone2phone&st=cse
