JavaScript

Introduction

In this tutorial, you will learn how to create a Client SDK application and write the code to make a phone call from your web app to a phone.

Two parts are needed to achieve this:

  • A web application that will make the voice call using the Client SDK.
  • A publicly accessible URL that serves instructions on how to handle the call. To accomplish this, you will create a webhook server using Node.js, Express and localtunnel.

Completed project

If you would like to follow along without building the app yourself, the completed project is available on Github - please see the app-to-phone-js folder.
