The phone rings at half past eight, and nobody is at the desk.

This is a simulated AI receptionist for a plumbing and heating company. Take the call yourself: choose what the caller says and watch what the agent writes down, what it refuses to guess, and when it decides the call needs a human.

SimulationNothing here calls a phone network or a language model, and no call is placed. The scripted answers are fixed, which is the point: they show the behaviour, the guardrails and the escalation rules. The production build runs the same script against a live speech pipeline, and each outcome says what it would do differently.
