i also use voip which i set-up for my wife back in cebu and im in US..i have her an n95 and install a voip on the phone (truphone) with a wifi access... was actually pretty cool for ten months we can call back and forth, cause truphone has a localized number(a US-based number) like vonage.. she can call anywhere in the US for free but when that ten months expire we can only do one-way call which is always free for me to call her truphone number.... wer using it for almost a year now and a good quality call...
