Linphone is a free VoIP application available on PCs running Linux, BSD operating systems such as FreeBSD,[3] Windows, or Mac OS X, and mobile phones running BlackBerry OS, Android,[5] Windows Phone,[6] or iOS.[7] It uses the Session Initiation Protocol (SIP) for communication and is licensed under the GNU General Public License (GPL). It supports IPv6, encryption via Transport Layer Security (TLS) and can be used behind network address translator (NAT), meaning it can run behind home routers. Linphone uses GTK+ for GUI and on Linux it can be also run as a console-mode application. It is compatible with telephony by using an Internet telephony service provider (ITSP).
