+#### 6. Experimental Warm Transfer
+
+In this mode, Vapi dials the destination number and places the caller on hold (with a default ringtone). If the destination answers, Vapi connects the calls. If voicemail is detected or the call isn't answered, Vapi plays a fallback message to the caller.
+
+- **Configuration:**
+
+  - Set the `mode` to `"warm-transfer-experimental"`.
+  - Provide a `message` to be spoken to the operator when they answer.
+  - Optionally define a `summaryPlan` that will take precedence over the message if enabled.
+  - Configure a `fallbackPlan` with a message and whether to end the call if transfer fails.
+  - When voicemail detection is enabled in the assistant configuration (with either Google or OpenAI provider), it will use that configuration to detect if a human answered the call. Note that only Google or OpenAI providers are supported for voicemail detection with transfer plans, even if the assistant configuration supports other providers like Twilio or Vapi.

+          ]
+        }
+      }
+    }
+  ]

 **Notes:**
 
 - In all warm transfer modes, the `{{transcript}}` variable contains the full transcript of the call and can be used within the `summaryPlan`.
