This interactive voice response system, built using Twilio's Programmable Voice and Java with Gradle, allows users to interact with a Party Cookie Dessert hotline through various phone numbers. The system consists of multiple servlets that handle different types of requests, including gathering user input, playing audio files, and redirecting calls to other phone lines. The `WelcomeServlet` handles the initial call, prompting the user to enter a number to navigate to different options. The `ShowServlet` handles the user's input, displaying options for connecting with the dessert shop or checking delivery status. The `ConnectServlet` handles connections to specific phone numbers. The system is configured using Twilio's webhook feature and can be tested by dialing the provided phone number.
