Objective: The platform reaches a system nobody would rebuild — the office phone system. 3CX was onboarded through the manifest layer over its own APIs, and gets the router, the typed table cards and the confirmation gate for free. The integration signs in as you — your own 3CX login, no admin credential — so it has exactly your rights. Persona: E2E Employee (demo). Duration: ~100 s.
Suggested narration (one segment per on-screen caption, in order):
Your phone system now lives in the same chat. It was onboarded with a single
manifest — an MCP generated from the PBX’s own APIs, nothing rebuilt.
Am I on a call right now? Your live calls from the real PBX, as the same
typed table every app gets.
Your team. The integration signs in as you, with your own 3CX login — so it
sees exactly what your phone app sees, and nothing more.
Names and extensions straight from the PBX. No admin credential anywhere,
no model in the numbers.
Changing your phone’s profile is consequential: calls will route
differently. So the chat stops and asks — nothing has happened yet.
The model proposed. The backend wrote this card. You decide.
Confirmed — and only then did the PBX change. The receipt is the snapshot.
And back again, through the same gate, with the same receipt. The phone
system ends exactly as it started.
Expense, Microsoft 365, tasks, phones. Any application, one manifest, the
same guarantees. That’s the platform.
