QuteCom (previously: WengoPhone) – a free, open source software SIP-compliant VoIP client developed by the QuteCom (previously OpenWengo).
The application is available for Windows, Linux, OS X and Windows Mobile. It allows users to make free phone calls over the Internet from one computer to other with SIP compatible software. You can also make calls to landlines or mobile phones, send SMS messages and make video calls. These functions are not associated with any specific SIP provider, and therefore can be used with any provider on the market.
The application is not under development any more, and the last version was released in 2011.
