In “Small meeting” mode, communication between participants are primarily sent through peer-to-peer connections, where audio and video streams are sent directly between participants and do not pass through any of our servers. Video and audio transmitted in the Service is then sent directly between the participants in a room and is encrypted (DTLS-SRTP) with client-generated encryption keys. In cases where a user is behind a strict firewall or NAT, video and audio need to be relayed via a TURN server, but end-to-end encryption is still maintained.</p> <p>
