Host a Galène room with the expected number of participants, including mobile and weaker connections. Test joining, screen sharing, audio recovery, and the effect of someone leaving and rejoining. Measure server bandwidth and CPU during the call, not just whether the room starts.
Review moderation and access settings before using it for private meetings. Document how to update and recover the server. A self-hosted video tool is a good fit when users can enter easily and the operator can handle a failed meeting.
