Jitsi Meet

Jitsi Meet is an open source video conferencing stack where people join browser based meetings, with a Videobridge server distributing media, Jicofo handling call signalling, and Jigasi bridging SIP calls into a room. Rooms can be locked with a password, guests can wait in a lobby, meetings can be recorded, and the media itself is protected with DTLS-SRTP encryption.

It suits distributed teams, online classes, and community calls that need screen sharing, chat, and participant controls without a commercial meeting service.

Deploying it on your own infrastructure keeps call traffic inside your network, avoids per-participant licence fees, and lets you set your own retention rules for recordings.
