Jitsi videobridge install and usage

Hello, im interested in jitsi videobridge. I need SFU mediaserver so i can send video stream from desktop and android app (native WebRTC) to the mediaserver which then forwards stream to clients that are connected to it. Im wondering what kind of signaling does videobridge use so i can connect streaming device with mediaserver and mediaserver with clients. I currently have implemented signalling over websockets by sending JSON object over server so two clients can establish peer connection.

Uses xmpp (in case of using it with jitsi-meet) or can be used with REST api: https://github.com/jitsi/jitsi-videobridge/blob/master/doc/rest-colibri.md
