Twilio logs all TwiML responses from your application via the Request Inspector, a tool to debug call flows. Twilio retains these requests for 90 days. In some cases, you may need to disable this feature to meet data retention requirements. You can turn off the Request Inspector in a few simple steps:

1. Login to your account at www.twilio.com/console.
2. Click Voice from the navigation on the left (you may need visit Explore Products first).
   
3. Click Settings -> General.
    
4. Under Request Inspector, switch to Disabled.
    
   
5. Click Save.
