phone call flow.txt

You've parsed the dictation and determined the user wants to call a contact...

1. Find the Contact
2. Get the Phone Number
3. Actually make the call

--------------------

func makeTheCall() {

  // if we don't have a Contact, get a Contact
  //    EXIT THIS FUNCTION
  
  // if we get here, we have Contact
  
  // if we don't have a Phone number, get a number
  //    EXIT THIS FUNCTION
  
  // if we get here, we have a Contact and a Phone number
  //    MAKE THE CALL
  
}

--------------------

...
  case "Call":
    resultMessage.text = "Switching to Phone for your call"
      // I'm assuming by this point you have determined that
      //   "actionType" is "Call" and
      //   you have word1 and word2
      makeTheCall()
      break
