By the way, you can use Gmail to call Canada as well, and if you travel abroad, you can also call any telephone from abroad to Canada (not sure about the USA but it should also work). Recently, I was able to call Canada from Germany, France, Luxembourg, and Hong Kong, so I assume it will work from almost anywhere in the world. However, when I told a friend in Hong Kong to install it so she could call my cell phone via Gmail, Google did not let her install it from her location.
