Linphone is a free and lightweight VoIP (Voice over IP) software that will help you stay in touch with people over internet using text, video, voice and instant messaging. The program uses the SIP (Session Initiation Protocol) protocol , which is an open standard used by Web phones. This application can be used with any SIP VoIP operator, even with the free SIP audio/video service.

Linphone features a SIP user agent which is compliant with the RFC3261 standard and is capable of supporting multiple calls at once. It also provides an useful set of call management features: resume, hold on with music, transfer call, and many more.

In order to offer the best audio quality, Linphone uses a wide range of audio codecs, including G711 (ulaw,alaw), GSM, opus, speex (narrow band and wideband), etc. Its functionality may be extended using traditional plug-ins which allows it to support AMR-WB, SILK, AMR, and iLBC as well.

For video calls, the software uses the following codecs: MPEG4, H263, VP8, H264, and H263-1998, providing resolutions of up to 1080p if it's used on powerful machines. It also provides full screen mode for video calls and allows you to initiate audio call conferences.

Linphone supports the IPv6 network protocol and is compatible with any webcam. Additionally, the program provides a comprehensive address book. The program also allows you to communicate via text instant messages using the SIMPLE standard.

Linphone also provides a set of powerful functions to enhance your calls, such as acoustic echo cancellation, digest authentication, support for DTMF (telephone tones) via SIP INFO or RFC2833 and support for multiple SIP accounts, including proxies, registrar, and outbound proxies.

The ICE technology will let you benefit from direct (fastest) media connection when the firewall allows it. In addition, the program offers codec bitrate adaptation to available bandwidth in order to offer the best quality of service.
