This tutorial demonstrates how to implement warm human handoffs for AI voice agents using the AssemblyAI Voice Agent API and Twilio. Rather than forcing callers to repeat themselves after a transfer, the approach packages conversation context into a human-readable summary and maintains a live transcript using Universal-3 Pro Streaming. The article compares SIP REFER transfers with conferenced bridges, provides a full implementation walkthrough, and uses a dental-office receptionist as a practical example of production-ready AI voice automation.
