Ok maybe this has been posted but I will post it again. I have a Google voice number (Maine #) I got a while back and I used to forward it to my land line when I had a land line and lived in Maine. Now that I am in DR I now forward it to my Google chat (after I installed the call and video app) and I can now call US numbers with my Google voice forwarded to google chat. On my Macbook. Free. Not the best quality sound but still, great to have. I have an Iphone (but no phone, just use it as an Ipod touch) and plan on trying out the call quality when I have a better connection with the phone. Right now I am on free wifi (thanks neighbors) and so can't really complain at all.
