I'm interested in a working version, to shrink the phone bill, which my wife with her sister in Italy are making big. Which are my best options? It's more cost effective to buy a separate device to take their ip from router or better install something on the iphone and go right? I do not even know what to ask now because I do not know much about this technology. I know that I have a linksys router and an internet connection wrt610N very good, which makes me think that I will not have traffic problems. I saw that there was a subscription to Skype 5.99 excluding VAT, is called Skype Unlimited Europe seems to me goodish. Course, limited to land lines. I have no idea if I have assigned a phone number where you can be called ... What do you think?
