If I could get Signal working on my Android tablet then that's what I'd use instead. As it is, most calls use Jitsi.

We're chronically short of bandwidth. If I were to self-host a Jitsi instance, would all video and audio streams come into my instance and radiate out to all participants, or is the protocol more peer-to-peer than that, so that adding more participants increases the bandwidth use for every participant? I'm assuming the former, because it scales better, but that makes self-hosting at home impossible.
