It would be great if we have the ability to use our own self hosted Jitsi server instead of hardcoded https://meet.jit.si/. This feature exists in Rocket Chat, and would be awesome to see in Riot.

From a privacy view it is essential to use a self-hosted server. If a third party controls the server, communication can be monitored and recorded.

config.json from custom Riot instances will contain hints about where to find and how to integrate a self hosted Jitsi. Additionally self-hosted integration servers like Dimension also integrate with custom Jitsi instances.

These configurations might eventually be reused, if present.

@bmarty i guess this also needs a ~"riotx-go-live" tag, considering #611 is just about the 1:1 resp. p2p-feature, #1294 has it and the announcement in TWIM 2020-05-01, that WebRTC audio and video calls and Jitsi conference integration will be implemented.

Would it be possible to have all members of the room (where conference call is made) get a call notification similar to one-one calls so they can accept or reject? Currently one has to create a conference call and then message members to join which is okay for tech savy users but average users just say they didn't get a call notification.

@dhrunia that would need to be off by default, because for rooms with >20 members, it would be insane for everyone to be notified just because one user decided to go on voice chat.

[sruggier]

Rather than a per-room setting, that sounds like something that the user should have to select each time they initiate a call.

As long as the hypothetical interface for that has a dynamic filter, along with select all and invert selection commands, it should be reasonable for most use cases.

On recent Skype we can initiate group call as Loud and as Silent - https://support.skype.com/en/faq/FA10613/how-do-i-make-a-call-in-skype#

when you start a video call, you can choose whether you want the call to ring everyone in the group or be ringless. Ringless calls will send a notification to participants without interrupting them with a ring and if anyone needs a little extra "nudge," you have the option to ring them individually.
