The meeting itself
How this is scored
Whether the call works: participant capacity, video and audio quality under load, screen sharing, breakout rooms, moderation, and what happens on a bad connection.
0 — Not a meeting tool: no multi-party video calls, only one-to-one calls or recorded video.
3 — Video meetings with screen sharing, chat and host controls such as mute-all.
5 — Meetings with a stated participant limit per plan, screen sharing, breakout rooms or a waiting room, and host moderation (mute, remove, assign co-hosts).
8 — Large meetings and webinars with published capacity limits, per-participant moderation and waiting rooms, layout control, simulcast or adaptive bitrate stated, and behaviour on constrained or mobile networks documented.
10 — Scale and control are engineering claims the vendor stands behind: capacity published per plan and per region, selective forwarding with adaptive quality documented, live streaming, hardware-room support, and diagnostics an admin can read after a bad call.
The Skeptic
Screen sharing, an in-call whiteboard where access is granted by the host, Active Speaker and Continuous Presence layouts at up to 1440p30, and H.264 SVC adaptive layering documented to hold up over LTE, 3G and unmanaged networks are all on the record. What I never found is a participant limit per plan, a waiting room, breakout rooms, or documented mute and remove moderation; the one capacity figure covers 300 concurrent recording views, not meeting seats. Strong engineering story, but the numbers a buyer sizes a contract against are missing. 1 2 3 7
