The text discusses creating an application using PHP and Nexmo's Voice API to automate tasks such as calling and sending SMS messages. The author shares their personal experience working in a web agency where distractions were common, leading them to design a solution to improve workflow efficiency. They outline the steps to set up a Voice Application on the Nexmo dashboard, including generating an application name, event URL, public/private key pair, and API credentials. The text then delves into implementing the Nexmo client in PHP, creating a reusable service class, and adding functionality to send SMS messages using the Nexmo messaging API or its existing client. Finally, the author shares their completed example code, which includes a controller that reacts to event webhooks sent by Nexmo after every call, echoing an alert if the call fails. The goal is to create a simple phone status checker that can be expanded upon in various ways.
