Host a realistic Jitsi Meet call with the number of participants and devices your team actually uses. Try screen sharing, joining by link, switching microphone or camera, and recovering after a brief network drop. Include someone on mobile and someone with a slow connection.
If you self-host, measure server load and decide who maintains updates and access controls. Clarify recording and data-retention needs before inviting sensitive discussions. A video tool is successful when the meeting remains usable under ordinary disruptions, not only on a fast local network.
