Liblinphone, high level VoIP library

Liblinphone is a high level library integrating all the SIP call and instant messaging features into a single easy to use API.

Usually telecommunications is made of two things: media (transport of voice or video, encoding and decoding...), and signaling (routing calls, ringing, accepting a call etc...).

Liblinphone aims at combining the two things together and doing most things automatically. This makes it easier to the programmer to implement video calls and instant messaging in any application, without being an expert in VoIP and telecommunications. Liblinphone is an open source library based on Mediastreamer2 for voice/video streaming, and belle-sip for SIP signaling.

Liblinphone is dual licensed. It can be licensed and distributed:

  • under GNU GPLv2 license - for free (open source)
  • under proprietary and commercial license to be used in closed source applications.
