# Serving Twilio On Prem

> Enterprises can now connect their Twilio infrastructure securely to Bolna

<Note>
  Bolna will provide access to docker image for hosting a Twilio application which you can deploy and connect with your Twilio account in your own infrastructure (AWS/GCP/DigitalOcean etc.)<br />
</Note>

## Login to docker

Use the docker login command to access the docker images: `docker login  -u bolnahq`.
You will be given a password for authentication.

## Inject Twilio credentials as environment variables

Create a `.env` file:

```.env theme={"system"}
# Bolna API and Websocket hosts
BOLNA_HOST=https://api.bolna.ai
BOLNA_WS_URL=wss://ws.bolna.dev

# Twilio credentials
TWILIO_ACCOUNT_SID=
TWILIO_AUTH_TOKEN=
TWILIO_API_KEY=
TWILIO_API_SECRET=

# Twilio external auth URL
TWILIO_CREDENTIALS_FROM_URL=

# Call recording enable/disable
RECORD_CALL=True
RECORDING_CHANNELS=dual

```

<Note>
  Bolna will never have access to the recordings.
</Note>

This `.env` file will be used to inject the variables while running the docker image.

## Starting docker

The following example illustrates on how to start the docker image using docker compose using the `.env` file in the same directory. You can have any other method of starting docker.

```docker-compose.yml theme={"system"}
services:
  twilio-app:
    image: bolnahq/twilio-app:1.0.0
    ports:
      - "8081:5000"
    env_file:
      - .env
```

The `twilio-app` service uses the `bolnahq/twilio-app:1.0.0` image which runs on `5000` port.

It then binds the container and the host machine to the exposed port, `8081`. You can specify any other port to bind the container with the host machine.
