Twilio logs all 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 HIPAA, PCI, or other data retention requirements. You can turn off the Request Inspector in a few simple steps:
2. Go to the Voice product area and click Configure.
2. Under Request Inspector, select "Disabled".
3. Click Save.
