Skype offer two things currently, the actual noises-over-internet stuff, and the gateway out to the 'real' telephony system. The former you can use one of the free voip implementations, the latter you need some kind of account for. There are services that offer SIP+RTP to phone gateways that should interoperate with the free VOIP implementations. I posted the URL of one a couple of weeks ago, but I forget what it was. - Steve
