# Live demo — hear Calltura answer a call with Calltura

> On this call, you'll hear Calltura live — we'll dial our own number and let the AI receptionist answer, same setup you'd get. You'll experience the greeting, natural conversation, and how it handles typical trade questions and bookings. Bring one real situation from your business (an emergency call scenario, a common quote question, a booking edge case) and we'll test the agent with it. If it looks like a fit, we'll walk through pricing and next steps at the end.
