RinGo  0.6

Make voice calls from any PC in the world. Free voice connectivity with Internet users. RinGo allows you to make calls from any place in the world from your PC without the use of PSTN (traditional telephony provider) for local and international calls. Instead of a regular phone you may use your PC equipped with headset and Internet-connection instead of regular telephone line. Regardless of your location you may call from your PC to any regular phone worldwide using special tariffs, much lower than standard international tariffs. Rates depend on destination.
