Skype gets all the press as a free Internet phone service -- a lot of it deserved. But Skype is far from the only game in town in terms of a free VOIP Internet phone service. Some VOIP providers offer free Internet phone services to anyone willing to limit calls to within the provider's network. This means that you can talk for free to anyone else subscribing to the same Internet phone service as you. These services can be limited -- no free access to public landlines, for example -- and certainly aren't ready for prime time in terms of replacing your current service.
