title: Twilio conference - Handle no one answering
body: <p>I want my main number to call two people and have them placed into a conference. My question is how to handle if one or both people don't answer the phone. If person A joins and is waiting for person B and they don't pick up, does the conference just end? Is person A waiting indefinitely? Not sure what is the best practice to gracefully handle this situation.</p>
  
  <p>Thanks,
  EE</p>
