/**
 * This test is configured with two options:
 * 1. The dialIn.enabled expectation. If set to true we assert the config.js settings for dial-in are set, the dial-in
 * panel (including the PIN number) is displayed in the UI, and the "more numbers" page is displayed. If it's set to
 * false we assert the config.js settings are not set, and the PIN is not displayed.
 * 2. The DIAL_IN_REST_URL environment variable. If this is set and the environment supports dial-in, we invite a
 * dial-in participant via this URL and assert that it joins the conference and sends media.
