The plan on Discord-style voice/video/screensharing features is Element Call (https://call.element.io) which is built to be embeddable into Matrix clients. It’s already in Element X, and is in Element Web/Desktop behind a labs flag. Meanwhile you can always embed Jitsi.
As far as I'm able to tell most call functionality is built into the JS SDK (is this true), so what will embedding Element Call actually gain me? The (beautiful!) UI?
* The ability to use the end-to-end encryption identity & verification from your normal Matrix account, by piggybacking on the 'host' matrix client. Whereas call.element.io is not remotely designed (at all) to work with your normal Matrix account, and doesn't have any of the E2EE UI hooked up, and instead relies on a shared secret to access E2EE rooms
* The ability to place VoIP calls inside existing Matrix rooms from your normal Matrix account.
* The ability to reliably background the app & lock the phone when on a call.
* The ability to receive inbound calls via push notifications and CallKit/ConnectionService - i.e. presenting the calls in the native dialer UI of the phone, and treating Element X like a VoIP dialer.
You get the same beautiful UI whether you use call.element.io directly or embed it inside another Matrix client like Element X :P
