JavaScript SIP library from the authors of the standard

    I already wrote a note on this topic, since then another JavaScript SIP library has become available . In the first article I mentioned it, but at that time all the information about the library included: a description of the authors and a video showing the work. Now the source code is open under the MIT license, there is documentation and a forum .

    It is noteworthy that this library is developed by the authors of the same standard, which describes the features of the SIP protocol when working on top of WebSocket. In addition, the developers indicate the following advantages:
    • lightweight, ~ 140KB
    • simple and powerful API
    • compatible with popular SIP servers
    • audio video calls; instant messaging
    • user status (this feature is unique while not available in other libraries)

    From myself, I will add to the advantages: the competence and responsiveness of the authors, they close the bug reports very quickly.

    Under the cut is a long detailed video with step-by-step instructions in the first half for those who want to try it on their own, and a demonstration of work in the second half (c 3:10). By the way, in the latest versions of Chrome, WebRTC - a protocol for exchanging audio-video data, is available and is enabled by default.
