Alternative to traditional land line set up

We are moving our telephone over to SKYPE. We intend to hang on to a basic line with France Telecom for a month or so - does anyone have any experiences with using Skpe only? - any other suggestions? We have WIBOX as an internet service at only 2 meg, and Orange is not an option in our area - bottom line is that we want to go over to " no phone" in the house. Thanks
