Automated call scheduling

A voice receptionist that handles appointment scheduling, rescheduling, and cancellation 24/7. The agent understands intent from natural speech rather than driving the caller through a phone menu.
Every call is logged with its transcript, recording, duration, and API cost, so the operation is measurable rather than a black box.
Appointment calls arrive outside business hours, and a missed call is usually a lost booking. An answering machine converts almost none of them.
Phone trees convert badly too, and the moment a caller needs something the tree does not anticipate — a genuine emergency, an unusual reschedule — the automation has to know it is out of its depth.
