For our US and Canadian readers: Turn your PC into a Skype Gateway
Televoce's PontiVoce (PonTEE VO-che) Server is an interesting piece of software that lets you create a 100% software-based Skype (News - Alert) gateway that leverages the Skype API to turn your PC into a Skype gateway for relaying calls. It's worth pointing out that Skype has offered free phone calls within the U.S. and Canada to help acquire more Skype users.
Using TeleVoce solution, you can extend this "free offer" to friends and family outside this free calling zone. All you do is find a friend in this free calling zone who has Skype running on his or her PC -- along with the PontiVoce server piece installed. The PontiVoce server can serve any number of users, but only one at a time. When the server PC is used to relay a call, the PC cannot be used for other Skype calls and the PC audio is dedicated to the call.
