Making international calls with Google Voice can be done in two ways.
Google Voice is a free Voice-over-Internet (VoIP) application for Google account users to make free outbound U.S. and Canada calls to landlines and mobile phones. To make international calls, you need to purchase credit through Google Checkout. International rates vary per country and are charged by the minute. To make international calls with Google Voice, you can use the Google Voice website or access the Google Voice phone system from your phone.
