+### 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.

+curl -X POST "http://localhost:7860/daily_start_bot" \                                                                                                        py pipecat
