body: <p>I am trying to make a twilio call with hosting an xml file on Twilio TwiMl Bins and hosting an mp3 file in Assets:</p>

  <p>I just want to say a simple sentence and then play a 5-10 second clip. Currently when I run my code:</p>
  
  <pre><code># Download the helper library from https://www.twilio.com/docs/python/install
  import os
  from twilio.rest import Client
  
  
  # Your Account Sid and Auth Token from twilio.com/console
  account_sid = "stuff"
  auth_token = "stuff"
  client = Client(account_sid, auth_token)
  
  call = client.calls.create(
              url="https://handler.twilio.com/twiml/EHdff1ba57cc168191864794c6c44c1723",
              from_="+1mytwilionumber",
              to="+1mynumber"                  
          )
  
  print(call.sid)
  </code></pre>
  
  <p>I just get a call - the trial message and then silence and then the call is concluded. Any tips?</p>
