Build an After-Hours AI Voice Agent with Retell AI & Copilot Studio
Automate your after-hours calls with an AI receptionist using Retail AI and Microsoft Copilot Studio. In this tutorial, you'll learn how to set up an AI phone agent that answers calls, collects key details, extracts information with AI, and logs everything into a clean spreadsheet—no more late-night voicemails or missed customers. In the video, I walk you through building the full workflow step-by-step. You’ll see how an AI voice agent handles a real after-hours customer call, gathers the name, callback number, and reason for calling, then sends the full transcript to Power Automate. From there, Copilot Studio extracts important fields like urgency, reason for the call, and contact details using a custom prompt and converts them into structured data. Finally, the system logs everything into Excel—giving you a neat call log every morning. You’ll also learn how to configure Retail AI voice agents, connect custom prompts, pass transcripts to automations, set up JSON parsing, and attach additional actions like email alerts for urgent calls. Whether you're a business owner or an automation builder, this setup saves time, improves customer response, and gives your business a more professional after-hours experience.
