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]

General features[edit]

  • SIP over WebSocket transport
  • Audio-video calls, instant messaging and presence
  • Pure JavaScript built from the ground up
  • Easy to use and powerful user API
  • Works with OverSIP, Kamailio, and Asterisk servers
  • SIP standards

Standards[edit]

JsSIP implements the following SIP specifications:

  • RFC 3261 — SIP: Session Initiation Protocol
  • RFC 3311 — SIP Update Method
  • RFC 3326 — The Reason Header Field for SIP
  • RFC 3327 — SIP Extension Header Field for Registering Non-Adjacent Contacts (Path header)
  • RFC 3428 — SIP Extension for Instant Messaging (MESSAGE method)
  • RFC 4028 — Session Timers in SIP
  • RFC 5626 — Managing Client-Initiated Connections in SIP (Outbound mechanism)
  • RFC 5954 — Essential Correction for IPv6 ABNF and URI Comparison in RFC 3261
  • RFC 6026 — Correct Transaction Handling for 2xx Responses to SIP INVITE Requests
  • RFC 7118 — The WebSocket Protocol as a Transport for SIP

Interoperability[edit]

SIP proxies, servers[edit]

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:

WebRTC web browsers[edit]

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.
