For example:
```shell
url -X "POST" "http://localhost:7860/daily_start_bot" \
curl -X "POST" "http://localhost:7860/daily_start_bot" \
-H 'Content-Type: application/json; charset=utf-8' \
-d $'{

}'
```
### 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
-H "Content-Type: application/json" \
-d '{"detectVoicemail": true}'
```
Example: Testing with Dial-Out:
```shell
curl -X POST "http://localhost:7860/daily_start_bot" \ py pipecat
-H "Content-Type: application/json" \
-d '{"dialoutNumber": "+18057145330", "detectVoicemail": true}'
```
### More information
For more configuration options, please consult [Daily's API documentation](https://docs.daily.co).
