Run the application

Now that the application is updated, you now need to expose a port your local machine is using. A good way to create an accessible URL is to use ngrok.

1. Refer to this tutorial to learn how to connect your local development server to the Nexmo API using an ngrok tunnel.

2. Next, run the application:

   npm start

3. On a separate device, make a phone call to your Smart Number. When the call is received by the application, it will generate a NCCO that will make a phone call out to the DEST_NUMBER.
