The client’s problem

Inbound calls needed a consistent greeting and qualification, and booking a call meant someone checking the calendar live.

What I built

Retell AI voice agents greet callers, collect business details, and gauge interest. A backend n8n workflow checks real calendar availability and confirms the appointment during the call.

The outcome

Callers are qualified the same way every time and leave with a confirmed slot from the real calendar.
