SQL & PL/SQL

I haven't really done any work with JSON before and I'm trying to wrap my head around using JSON_TABLE to parse data into my database. I have a JSON document (sample from the docs):

{"PONumber" : 1600,
  "Reference" : "ABULL-20140421",
  "Requestor" : "Alexis Bull",
  "User" : "ABULL",
  "CostCenter" : "A50",
  "ShippingInstructions" : {"name" : "Alexis Bull",
  "Address": {"street" : "200 Sporting Green",
  "city" : "South San Francisco",
  "state" : "CA",
  "zipCode" : 99236,
  "country" : "United States of America"},
  "Phone" : [
     {"type" : "Office", "number" : "909-555-7307"},
     {"type" : "Mobile", "number" : "415-555-1234"}
     ]},
  "Special Instructions" : null,
  "AllowPartialShipment" : true,
  "LineItems" : [
     {"ItemNumber" : 1,
     "Part" : {"Description" : "One Magic Christmas",
     "UnitPrice" : 19.95,
     "UPCCode" : 13131092899},
     "Quantity" : 9.0},
     {"ItemNumber" : 2,
     "Part" : {"Description" : "Lethal Weapon",
     "UnitPrice" : 19.95,
     "UPCCode" : 85391628927},
     "Quantity" : 5.0}
     ]}

What I'm trying to do is fetch a value from a nested array and display is as a column. For example, I'd want the "Office" and "Mobile" phone numbers to be displayed like this:

What would be the best way to do this? All the examples I see in the documentation return each phone number type as an individual row like

this isn't what I'm after.
