title: Retrieving phone number when using Twilio Flex
body: <p>I'm using Twilio Flex, with incoming SMS messages first going through a Studio flow. Specifically, I am querying whether the incoming phone number has texted before (or is a subscriber) by checking it against a CRM database.</p>
  <p>However, it looks like Flex sends a hash of the incoming phone number to Studio. So, when I use <code>{{trigger.message.From}}</code> I get something like <strong>SMS_XXXXXXXXXXXXXXXXX</strong>.</p>
  <p>Is there a way to retrieve the phone number in Studio when using Flex?</p>
  <p>The flow otherwise functions as it should without Flex.</p>
  <p>Thanks!</p>
