# Rasa Open Source Configuration

##### Warning
These settings only work if you deployed Rasa Open Source via the Rasa Enterprise Helm chart. It's possible to deploy Rasa Open Source using the Rasa Enterprise Helm chart, but this option is deprecated and will be removed in the future.

See the [Rasa Helm chart](https://github.com/RasaHQ/helm-charts/tree/main/charts/rasa#configuring-messaging-channels) to learn how to configure Rasa Open Source Channels for deployment that was deployed via the Rasa Helm chart.

## Configuring Messaging and Voice Channels
To configure the [messaging and voice channels](/content/docs/rasa/user-guide/messaging-and-voice-channels/index.html) for Rasa Open Source servers started by the Rasa Enterprise Helm chart, add the credentials that would usually go in `credentials.yml` in `values.yml` as shown in this example:

```yaml
rasa:
  additionalChannelCredentials:
    socketio:
      user_message_evt: user_uttered
      bot_message_evt: bot_uttered
      session_persistence: true/false
```
