Random Facts Voice Call With PHP, Uselessfacts and AWS Lambda

You have successfully created a PHP application hosted on AWS Lambda that listens for a specific webhook URL, confirms the caller's number, and converts a random fact from text to speech using Vonage's API. The application uses Slim Framework for routing, GuzzleHttp for making API requests, Bref for support on PHP on AWS Lambda, and Vonage's PHP client to handle incoming webhook requests. You have also deployed the code to AWS Lambda and created an application in Vonage to enable your virtual phone number to know which endpoint it needs to request when a call is made.
