This morning, when I opened my gmail account I found an alert about Google Voice call to phone.

It announces to give free call to USA and Canada until the end of this month (August 2010).

Unfortunately, it’s not available to call in Cambodia yet but you can ring from your gmail to your Cambodian mobile phone.
