Introduction

In this tutorial, you will learn how to create a web application using the Vonage JavaScript Client SDK, and then write the code to receive a phone call with your web app.

Two parts are needed to achieve this:

• An web application that will receive 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 phone-to-app-js folder.

This tutorial uses @vonage/client-sdk version 1.0 or greater
