Vonage

Basic Rasa configuration

Create or edit your credentials.yml and add a new channel configuration:

credentials.yml

vonage:
  server_url: "<your-domain>"
  username: "<username>"
  password: "<password>"
  asr:
    name: "deepgram"  # or "azure"
    # ASR-specific configuration
  tts:
    name: "deepgram"  # or "cartesia", "azure"
    # TTS-specific configuration
  interruptions:  # optional
    enabled: true
    min_words: 3

You can run that assistant using rasa run. To configure the Vonage channel, you will need a URL to your Rasa assistant. You can use a tunneling solution like ngrok to expose your assistant for development.

Bot URLs for developmentVisit this section to learn how to generate the required bot URL when testing the channel on your local machine.

Configuring Vonage

To route calls to your Rasa assistant, you need to have a Vonage account and a phone number.

Once logged in, buy or port your number to Vonage.

Create an Application with Voice capabilities. To route calls to your assistant, Vonage needs an Answer webhook URL and Event webhook URL. You’ll either need to deploy your assistant to a server or use a tunneling solution like ngrok for development. The Answer webhook URL will be in the format wss://<your-server>/webhooks/vonage/webhook or if using ngrok, it will look like this: wss://recently-communal-duckling.ngrok-free.app/webhooks/vonage/webhook The Event webhook URL will be in the format wss://<your-server>/webhooks/vonage/call_status or in the case of ngrok look like this: wss://recently-communal-duckling.ngrok-free.app/webhooks/vonage/call_status

After saving the application, in the Link numbers section, link the chosen number to your application.
