There are VOIP Plans that have no monthly or per-call charges under certain conditions. Skype is perhaps the best-known, with talk services from AOL, Microsoft and Google right behind them. It's true that these services can be free. But look at the fine print. Skype, for example, is free only if you're calling other Skype users. Calling anyone outside the network costs money. This might work well for you, if your frequent calling partners are also on Skype. Otherwise, it's just another phone plan.
