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:

  • FreeSWITCH
  • FRAFOS ABC WebRTC Gateway Archived 20 July 2016 at the Wayback Machine
  • OverSIP
  • Kamailio
  • Asterisk
  • reSIProcate and repro

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.
