JsSIP is a library for the programming language JavaScript. It takes advantage of SIP and WebRTC to provide a fully featured SIP endpoint in any website. JsSIP allows any website to get real-time communication features using audio and video. It makes it possible to build SIP user agents that send and receive audio and video calls as well as and text messages.[2]

Interoperability
[edit | edit source]SIP proxies, servers
[edit | edit source]JsSIP uses the SIP over WebSocket transport for sending and receiving SIP requests and responses, and thus, it requires a SIP proxy/server with WebSocket support. Currently the following SIP servers have been tested and are using JsSIP as the basis for their WebRTC Gateway functionality:
- FreeSWITCH
- FRAFOS ABC WebRTC Gateway Archived 20 July 2016 at the Wayback Machine
- OverSIP
- Kamailio
- Asterisk
- reSIProcate and repro
WebRTC web browsers
[edit | edit source]At the media plane (audio calls), JsSIP version 0.2.0 works with Chrome browser from version 24. At the signaling plane (SIP protocol), JsSIP runs in any WebSocket capable browser.
