9. BUYING NUMBERS
   You can buy phone numbers
   through Twilio
   
   In the US, you can choose by area
   code, or get a toll-free number
   
   Toll-free numbers have higher
   costs (per month, and per
   minute)

10. TWIML APPS
    Now that you have a number,
    how do you point it to your
    application?
    
    TwiML Apps map voice and
    messaging requests to a URL on
    the public internet
    
    You can also map voice and SMS
    URLs directly to a number

12. PROVIDING TWIML TO TWILIO
    After receiving a voice or SMS
    call to a Twilio phone number,
    Twilio will make an HTTP
    Request to the specified URL
    
    Twilio passes along metadata
    about the incoming call or text
    message
    
    Your web application returns
    TwiML to Twilio
