Python

There are two methods for creating a Voice application:

  1. Using the Vonage CLI
  2. Using the Dashboard

Each of these methods is described in the following sections.

How to create a Voice application using the Vonage CLI

To create your application using the Vonage CLI, enter the following command into the shell replacing NGROK_HOST_NAME with the ngrok host that you got when you set up ngrok:

To create your application using the Vonage CLI, enter the following command:

Then add voice capabilities to your application (use the host name from ngrok in place of example.com)

This command creates a Vonage Application with Voice capability. It
configures the Application with your answer and event webhook URLs and generates a private key file private.key, which you should save in your project directory.

The command returns a unique Application ID. Use this Application ID to link your Vonage virtual number to your Application by executing the following:

This will link that Vonage Virtual Number to your application, which will cause all voice events occurring for that number to be routed to your designated URLs.

How to create a Voice application using the Dashboard

You can create Voice applications in the Dashboard.

To create your application using the Dashboard:

  1. Under Applications in the Dashboard, click the Create a new application button.

  2. Under Name, enter the Application name. Choose a name for ease of future reference.

  3. Click the button Generate public and private key. This will create a public/private key pair and the private key will be downloaded by your browser. Save the private key that was generated.

  4. Under Capabilities select the Voice button.

  5. In the Answer URL box, enter the URL for your inbound calls webhook, for example, http://example.com/webhooks/answer.

  6. In the Event URL box, enter the URL for your call status webhook, for example, http://example.com/webhooks/events.

  7. Click the Generate new application button.

  8. You are now taken to the next step of the Create Application procedure where you should link your Vonage number to the application.

You have now created your application.

NOTE: Before testing your application ensure that your webhooks are configured and your webhook server is running.
