+### Voicemail detection
+
+To start the bot and test voicemail detection, send a POST request to /daily_start_bot with "detectVoicemail": true in the request body.
+
+- If you only include `"detectVoicemail": true`, the bot will not dial out. Instead, you can test it in Daily Prebuilt by visiting the URL provided in the response.
+- If you include both `"detectVoicemail": true` and a phone number under `"dialoutNumber"`, the bot will dial out to that number.
+
+Example: Testing in Daily Prebuilt:
+
+```shell
+curl -X POST "http://localhost:7860/daily_start_bot" \                                                                                                        py pipecat

+     -d '{"detectVoicemail": true}'
+```
+
+Example: Testing with Dial-Out:
+
+```shell
+curl -X POST "http://localhost:7860/daily_start_bot" \                                                                                                        py pipecat

+
+            ### **Standard Operating Procedure:**
+
+            #### **Step 1: Detect if You Are Speaking to Voicemail**
+            - If you hear **any variation** of the following:
+            - **"Please leave a message after the beep."**
+            - **"No one is available to take your call."**
+            - **"Record your message after the tone."**
+            - **Any phrase that suggests an answering machine or voicemail.**
+            - **ASSUME IT IS A VOICEMAIL. DO NOT WAIT FOR MORE CONFIRMATION.**
+
+            #### **Step 2: Leave a Voicemail Message**
+            - Immediately say:  
+            *"Hello, this is a message for Pipecat example user. This is Chatbot. Please call back on 123-456-7891. Thank you."*
+            - **IMMEDIATELY AFTER LEAVING THE MESSAGE, CALL `terminate_call`.**
+            - **DO NOT SPEAK AFTER CALLING `terminate_call`.**
+            - **FAILURE TO CALL `terminate_call` IMMEDIATELY IS A MISTAKE.**
+
+            #### **Step 3: If Speaking to a Human**
+            - If the call is answered by a human, say:  
+            *"Oh, hello! I'm a friendly chatbot. Is there anything I can help you with?"*
+            - Keep responses **brief and helpful**.
+            - If the user no longer needs assistance, **call `terminate_call` immediately.**
+
+            ---
+
+            ### **General Rules**
+            - **DO NOT continue speaking after leaving a voicemail.**
+            - **DO NOT wait after a voicemail message. ALWAYS call `terminate_call` immediately.**
+            - Your output will be converted to audio, so **do not include special characters or formatting.**
