[Bolna.ai](https://bolna.ai) is a platform for building conversational voice agents. Integrating with Vobiz gives your agents global calling capabilities through premium SIP trunking with superior reliability.

## What you'll build

A no-code integration that lets your Bolna voice agents make outbound calls and answer inbound calls on Vobiz phone numbers, with provisioning available directly inside the Bolna platform.

## Prerequisites

* **Vobiz account** with active balance - you need your `Auth Token` and `Auth Secret` from the Vobiz Console → [Create account](https://console.vobiz.ai/auth/signup)
* **Bolna.ai account** → [Sign up at bolna.ai](https://bolna.ai)

## Step 1: Add Vobiz as a provider

Log in to the [Bolna platform](https://platform.bolna.ai) and navigate to the **Providers** section.

Locate the Vobiz provider option and enter your **Vobiz Auth Token** and **Auth Secret**.

<Tip>
  Find your API credentials in the Vobiz Console under **Dashboard → Settings → API Keys**.
</Tip>

| Credential    | Where to find                       |
| ------------- | ----------------------------------- |
| `Auth Token`  | Vobiz Console → Settings → API Keys |
| `Auth Secret` | Vobiz Console → Settings → API Keys |

Once you've entered your credentials, the Vobiz telephony status shows as **Connected**.

<img className="block w-full rounded-xl border border-gray-200 my-4 shadow-sm" src="https://mintcdn.com/vobizai/OZ7y9Kg025aXyvCH/images/bolna/vobiz%20connected.png?fit=max&auto=format&n=OZ7y9Kg025aXyvCH&q=85&s=cd611f008fb819dd5b1dc6a47402b1f3" alt="Vobiz connected" width="549" height="167" data-path="images/bolna/vobiz connected.png" />

<Check>
  You've successfully authorized Bolna to use Vobiz for making phone calls.
</Check>

## Step 2: Configure outbound calls

To enable your agents to make outbound calls, select **Vobiz** as the telephony provider in the agent settings.

In the **Call Agent** section, select **Vobiz** from the provider dropdown.

<Note>
  Your AI agent will now route outbound calls directly through your Vobiz SIP trunk.
</Note>

## Step 3: Set up inbound calls

Configure which agent answers incoming calls to your Vobiz numbers.

<img className="block w-full rounded-xl border border-gray-200 my-4 shadow-sm" src="https://mintcdn.com/vobizai/OZ7y9Kg025aXyvCH/images/bolna/set%20inbound%20agent.png?fit=max&auto=format&n=OZ7y9Kg025aXyvCH&q=85&s=c728dfe3d93101f844f2ccb90c18708b" alt="Set inbound agent" width="392" height="157" data-path="images/bolna/set inbound agent.png" />

1. Go to the **Inbound** section in Bolna.
2. Select the agent that will handle incoming calls.
3. Select the specific Vobiz phone numbers to assign to the chosen agent.

## Step 4: Assign phone numbers

Provision and buy new phone numbers directly within the Bolna.ai platform using Vobiz inventory.

<Tip>
  If you already have numbers in your Vobiz account, they appear automatically in the selection list once you've added your credentials as a provider.
