### Answer When you turn off the whisper message during a warm transfer in the Call Transfer Node, the whisper message feature is simply disabled [(1) ]() . The whisper message is described as "a message spoken privately to the transfer target before connecting them to the original caller" . If you disable the whisper message, the AI agent will not deliver that private briefing to the person picking up the phone . However, you still have other warm transfer configuration options available : - **Human detection**: When enabled, the agent will check if a human is present after the transfer target answers, and the original caller will only be connected once a human is detected - **Auto-greet**: If enabled, the agent will immediately say "Hello" when the transfer target picks up, which encourages a response and increases the likelihood of detecting a human - **Three-way message**: This is an optional message spoken to both the transfer target and the original caller once the connection is established So to directly answer your question: No, turning off the whisper message doesn't mean the AI has a conversation with the person picking up. The whisper message is just a one-way private briefing. Without it, the transfer proceeds based on your other configured settings (like human detection and three-way messages) .

### Answer Not exactly. Even with both whisper and three-way messages turned off, the warm transfer still includes human detection by default [(1) ]() . When human detection is enabled, the AI agent will check if a human is present after the transfer target answers, and the original caller will only be connected once a human is detected . The agent detection timeout setting determines the maximum amount of time the AI agent will wait to determine whether the transfer target is a human—the caller is connected only if human detection succeeds within this timeframe, otherwise the transfer is marked as failed . The default timeout is 30 seconds . So the transfer flow would be: 1. Transfer target picks up 2. AI agent performs human detection (with optional auto-greet if enabled) 3. Once human is confirmed, the original caller is connected 4. No whisper or three-way messages are delivered If you want a truly direct transfer with no AI interaction at the transfer destination, you'd need to use a cold transfer instead of warm transfer [(1) ]() [(2) ]() .
