Can Jitsi Videobridge be used with Conferencing endpoints?

Good day,

I am still new to the wide wide world of video conferencing. So my question is simple, can I connect my Avaya XT 5000 to a OpenFire server running Jitsi videobridge and have it work for audio and video? The Avaya XT 5000 is able to use SIP and H.323. I currently have the server running and working for desktop clients. We do not have a SIP server established as of now, but could.

Thank you for your time
