## Evaluation Prompt

# Task
Using https://www.twilio.com/docs/voice/api, complete the following task:

Using the Twilio Python SDK, build me a script that performs a voice telephony workflow:

1. Install the official Twilio Python SDK (pip install)
2. Check the Twilio documentation to determine the easiest programmable voice workflow
3. **Preferred:** Create a ***** outbound voice call to "+15551234567" using a valid sandbox/***** caller ID and print the API response as JSON.
   If the provider requires a public answer URL, callback URL, or hosted instructions, use a simple public example from the official docs.
4. **If outbound voice calls are not practical in ***** mode but telephony messaging is supported:** Send a ***** SMS message to "+15551234567" and print the API response as JSON.
5. Print the response fields that identify the call or message and its status

You MUST use the official Twilio Python SDK — do not make raw HTTP/REST calls. 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/app && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
