I'm sure this has been answered -- I did do a search here as well as on google's forum and most replies are over one year old.

I only recently discovered that one can now call directly from gmail account using their google voice number without having to use/go through either a linked landline or mobile number.

So I told my son in Taiwan to try calling home using google voice directly via his pc. No luck. When he calls, our phone at home rings but can only leave a message. When I call his GV, same - can only leave voice mail. And of course, he gets an email alert. Interesting, text messages can be sent back and forth.

Can someone confirm whether it's possible to make a call back stateside when overseas?
