### Answer For the issue with your voice assistant not producing sound, it might be beneficial to check the assistant's configuration, especially if there were any changes or updates since it last worked. Verifying the assistant's setup in the Vapi dashboard could be helpful. Additionally, ensuring that the Twilio integration is correctly configured is crucial. Sometimes, issues can arise from changes on the Twilio side or within the assistant's settings in Vapi. For setting up your voice assistant in production with Twilio active, you can follow the process of importing a Twilio number into Vapi as outlined in the documentation. This involves using your Twilio credentials to verify the number and configure it with Vapi services [(1)]() . Furthermore, ensure that your assistant is correctly configured to handle inbound and outbound calls as needed. You might want to review the endpoints and configurations related to creating phone calls [(2)]() , handling phone numbers [(1)]() , and managing assistants [(3)]() for a comprehensive setup. If you've verified these configurations and the issue persists, it could be related to a specific error or configuration issue that's not directly covered in the information provided. In such cases, checking the call logs in Vapi's dashboard for any errors or unusual statuses that could indicate what went wrong might offer additional insights.
