Warm Transfer
A call transfer where the AI briefs a human agent with context before connecting the caller.
A warm transfer (also called an attended transfer) is a call transfer method where the transferring party — in this context, an AI voice agent — speaks to the receiving party before connecting the original caller. This ensures the human agent has context before taking the call.
Warm transfer vs. cold transfer
- Cold transfer (blind transfer): The call is transferred directly to the new destination without any introduction. The human agent receives the caller with no prior context and must re-ask for information the AI already collected.
- Warm transfer: The AI agent places the caller on hold, connects to the human agent, and provides a verbal or data summary — then bridges the caller through. The human agent is already briefed.
How warm transfers work in AI voice agents
- The AI voice agent determines that escalation is needed (caller request, sentiment trigger, topic outside agent scope)
- The AI places the caller on hold with appropriate hold messaging
- The AI connects to the available human agent and delivers a briefing: "Hi, I have John Smith on the line. He's calling about his March 15 appointment and wants to discuss a billing dispute. His account number is 48291."
- The human agent acknowledges, and the AI bridges the call through
Data transfer: Modern implementations like TurboCall also push a structured data packet to the human agent's screen (via CRM integration) simultaneously — showing the full call transcript, caller details, and AI-captured data before the agent says hello.
