So in the initial beta we haven't turned on E2EE, purely because it will make it way harder to debug any problems which surface. However, at this rate, things are looking pretty stable and i'd expect us to enable it in the next few weeks. It uses normal Matrix E2EE, which means a Double Ratchet between the pairs of devices participating in a given conversation, which is then used to secure the signalling which is used to set up the calls between the devices. The call media is transport-layer encrypted via DTLS and SRTP, so as long as the signalling with the DTLS fingerprints is secured by Matrix E2EE, the whole call fabric will be E2EE. https://github.com/matrix-org/matrix-js-sdk/pull/2002 https://github.com/matrix-org/matrix-js-sdk/pull/2002 is the PR we actually need to merge in order to enable E2EE on it, ftr.
