title: Twilio: Don't want to keep logs of voice callers' numbers
body: <p>I use Twilio to operate an automated phone line that connects callers to resources for some very sensitive topics. If the phone numbers of callers were revealed due to a data breach or subpoena, it could have negative consequences for them. There's no need for us to log callers' numbers, and ideally I'd like to not store that information at all. However, these numbers show up in my usage logs:</p>

  <p>I've searched for ways to prevent these numbers from being logged or to delete them after they've been logged, but I can't find anything documented. Is there a way to do this? </p>
