This application should give you a ready-made starting point for writing your own voice apps with Twilio Client. Before we begin, we need to collect all the config values we need to run the application:

1. Create a configuration file for your application:

   cp .env.example .env

2. Edit config.js with the four configuration parameters we gathered from above.

3. Next, we need to install our dependencies from npm:

   npm install

4. Now we should be all set! Run the application using npm.

   npm start

   Your application should now be running at http://localhost:3000. Leave the server running and continue on in another command window.

5. Download and install ngrok

6. Run ngrok:

   ngrok http 3000

7. When ngrok starts up, it will assign a unique URL to your tunnel. It might be something like https://asdf456.ngrok.io. Take note of this. Note you must use the https URL, otherwise some browsers will block microphone access.

8. Configure your TwiML app's Voice "REQUEST URL" to be your ngrok URL plus /voice. For example:

   

   You should now be ready to rock! Make some phone calls. Open it on another device and call yourself. Note that Twilio Client requires WebRTC enabled browsers, so Edge and Internet Explorer will not work for testing. We'd recommend Google Chrome or Mozilla Firefox instead.
