This document discusses how to create a call ringout application in Java using the RingCentral API:
1. Create a Maven project in Eclipse or Spring Tool Suite and add the RingCentral dependency to pom.xml.
2. Create a main Java class and get credentials by creating a RingCentral app in the developer account.
3. Authorize the app using username, extension, and password and place a call by specifying the "from" and "to" phone numbers in the request body.
4. Run the application to see the call status response for the ringout call.
