setup element call as an alternative to jitsi

[BentEngbers]

Element recently announced that element call is enabled by default in element x and element desktop https://element.io/blog/we-have-lift-off-element-x-call-and-server-suite-are-ready.

There is documentation available about how to setup element call with the latest LTS version of ESS
https://ems-docs.element.io/books/element-on-premise-documentation-lts-2404/page/setting-up-element-call.

Maybe we can track progress in this issue?

I have created a PR to try and add Element call to the playbook.
#3562

I have not successfully seen media flowing through the livekit instance and I am trying to understand why the PR works you and not me

I tried both element-web and element-call and I see a blank screen in the call window

I am running into this error. Any ideas?

@saket424 yes, ita because it's expecting to lookup a user in Matrix Authentication Service (MAS), which isn't implement in this playbook yet. MAS is a requirement of Element Call Sonita can perform user lookups. You'll notice the error in your last comment references openID (openIDSFU.ts:71:23).

@wjbeckett
If you have a temporary standalone MAS recipe that I can augment with your nearly complete element-call PR, I would be grateful and ready to try it even if it is not fully in ansible

Here is another blog post I cam across related to MAS just as a reference

@wjbeckett I've downloaded your version and applied it to my server. I've even seen Update Element Call configuration in config.json and Update Element Call configuration in config.json tasks were succeed. But still, it's sending request to "https://livekit-jwt.call.element.io/sfu/get" when I check network tab on my browser while joining video rooms. I've tried to reset browser cache and disable cloudflare cache but still it is same. I'm getting "Failed to look up user info from homeserver" error, also with Delayed events are not supported on this server (not sure if this one is related)
Is there any way to fix it for now?
