listen to a real call

A real recorded phone call answered by a Plivo voice agent at a dental clinic, shown with its transcript lighting up word by word. The caller asks to reschedule a Friday cleaning; the agent looks up the booking, checks availability, books a new slot, and sends a confirmation text, calling four tools along the way. Press play to hear the recording.
