Enter your number and receive a call
When you start the phone call, this code makes a request to Twilio providing both a phone number to call, and a server location that will provide TwiML instructions on how to route the phone call.
This call logic relies on a number of TwiML verbs including <Say> to speak audio to the caller, <Gather> to take dialpad input from the user, and <Play> to play audio back to the user.
