Jitsi (formerly SIP Communicator) is a set of open-source projects that allows you to easily build and deploy secure videoconferencing solutions. It’s privacy focused, compatible with WebRTC, and supports advanced video routing concepts such as simulcast, bandwidth estimations, and scalable video coding.
At the centre of Jitsi are Jitsi Videobridge and Jitsi Meet, which let you have conferences on the internet, while other projects in the community enable other features such as audio, dial-in, recording, and simulcasting.
Jitsi is written in Java and some native code.
Jitsi combines open-source projects that you can use to meet your communication needs:
- Supports many protocols including SIP, XMPP/Jabber, AIM/ICQ, and IRC.
- Compatible with WebRTC, the open standard for Web communication.
- Supports advanced video routing concepts such as simulcast, bandwidth estimations, scalable video coding and many others.
- Built-in IPv6, NAT traversal and DNSSEC.
- Attended and blind call transfer.
- Auto away.
- Auto re-connect.
- Auto answer and Auto Forward.
- Call recording.
- Call encryption with SRTP and ZRTP.
- Conference calls.
- Direct media connection establishment with the ICE protocol.
- Desktop Streaming.
- Encrypted password storage using a master password.
- File transfer for XMPP, AIM/ICQ, Windows Live Messenger, YIM.
- Instant messaging encryption with OTR (end-to-end encrypted).
- Media relaying with the TURN protocol.
- Message Waiting Indication (RFC 3842).
- Voice and video calls for SIP and XMPP using H.264 and H.263 or VP8 for video encoding.
- Wideband audio with SILK, G.722, Speex and Opus.
- DTMF support with SIP INFO, RTP (RFC 2833/RFC 4733), In-band.
- Zeroconf via mDNS/DNS-SD ( Apple’s Bonjour).
- Group video support (Jitsi Videobridge).
- Packet loss concealment with the SILK and Opus codecs.
Features of the other packages:
- Efficient collaboration.
- Stream desktops or some windows.
- Supports document editing with Etherpad.
- Jitsi Videobridge – a WebRTC compatible video router or SFU that lets build highly scalable video conferencing infrastructure (i.e., up to hundreds of conferences per server).
- Does not mix the video channels into a composite video stream, but only relays the received video channels to all call participants.
- Not dependent on CPU horsepower. Lower latency, better quality and, if you are running your own service, a much more scalable and inexpensive solution.
- JItsi GAteway to SIP – a server-side application that links allows regular SIP clients to join JitMeet conferences hosted by Jitsi Videobridge.
- Jitsi Meet API library – use Jitsi Meet API to create Jitsi Meet video conferences with a custom GUI.
- Cross-platform support – software runs on Linux, Windows, Mac OS X, Android, and iOS.
- Internationalization support – Asturian, English, French, German, Bulgarian, Japanese, Spanish, Italian, Romanian, Greek and 25 more languages are supported.
