Unable to parse user settings `tsp.call_out_countries`

[Jericho]

This JSON node (any many others) are undocumented in the Zoom API documentation and therefore I don't know how to parse it.

I reported the lack of documentation here:
https://devforum.zoom.us/t/user-settings-documentation/135736/3

Here's a snippet of the documentation that shows a sample of this property but since there is no documentation, I don't know what to do with this property:

"tsp": {
    "call_out": true,
    "call_out_countries": [
      {}
    ],

I will comment out the "call_out_countries" property for the time being, until we get some help from the Zoom team.
