# Vobiz

> Connect your own Vobiz account to Sarvam Voice Agents for inbound and outbound calls: add your Auth ID and Auth Token, then create a voice application.

Connect your own Vobiz account to Voice Agents for inbound and outbound voice calling.

Setup has two parts: add your Vobiz credentials on Voice Agents, then create a voice application on Vobiz's platform.

> **Tip**
>
> Don't have a Vobiz account? You don't need one. Use [Rent from Sarvam](/voice-agents/deploy/telephony/rent-from-sarvam) instead - Sarvam manages everything for you, with no provider setup required.

> **Note**
>
> **Before you start:** an active Vobiz account with admin access to its platform, at least one Vobiz phone number, and Voice Agents access with permission to add telephony connections (**Deploy → Phone Numbers**).

## Watch the setup

## Add the connection on Voice Agents

Voice Agents needs two account-level values from Vobiz - your **Auth ID** and **Auth Token**.

#### Get your Auth Token and Auth ID (on Vobiz)

Log in to the Vobiz platform. In the left panel, go to **Voice → Voice Applications** and open the **Overview** tab - your account's **Auth Token** and **Auth ID** are shown there.

#### Enter and save on Voice Agents

In Voice Agents, go to **Deploy → Phone Numbers → Add Connection**, select **Vobiz**, enter both values, and click **Save**. The connection now appears under **Deploy → Phone Numbers**.

---

## Create the voice application on Vobiz

Create a voice application that links incoming calls to your Sarvam agent, then attach your numbers to it.

#### Open Voice Applications

In the Vobiz platform, go to **Voice → Voice Applications** and switch to the **Applications** tab.

#### Create a new application

Click **Create New Application** and enter:

| Field           | Value                                                      |
| --------------- | ---------------------------------------------------------- |
| **Name**        | Your choice (e.g. `sarvam-prod`)                           |
| **Answer URL**  | `https://apps.sarvam.ai/api/app-runtime/v1/channels/vobiz` |
| **Hangup URL**  | `https://apps.sarvam.ai/api/app-runtime/v1/channels/vobiz` |
| **HTTP method** | POST (for both URLs)                                       |

> **Note**
>
> The Answer URL and Hangup URL use the same Sarvam endpoint by design - Sarvam handles both call events at that address.

#### Save the application

Save the application.

#### Attach phone numbers

Once the application is created, attach the phone numbers you want to use to it.

> **Warning**
>
> Phone numbers you add on Voice Agents must also be attached to this voice application on Vobiz. Both sides need to know about the number.

---

## After connecting

Once both sides are configured:

#### Add your phone numbers

In Voice Agents, open your Vobiz connection under **Deploy → Phone Numbers** and add the numbers. See [Manage Phone Numbers](/voice-agents/deploy/telephony/manage-numbers).

#### Route calls to an agent

For incoming calls, create an [Inbound deployment](/voice-agents/deploy/inbounds) to route each number to an agent. To dial out, add the numbers to a [Campaign](/voice-agents/deploy/campaigns).

#### Verify with a test call

Place a test call to (or from) a number and confirm your agent connects. See [Manage Phone Numbers](/voice-agents/deploy/telephony/manage-numbers) for the test-call steps.

> **Note**
>
> **Outbound calling** uses this same connection - dial out by adding the numbers to a [Campaign](/voice-agents/deploy/campaigns). No separate credentials are required.

> **Warning**
>
> **Call queuing:** If it's enabled on your Vobiz account, Vobiz holds each outbound call before connecting it to Sarvam - and calls that connect too late are marked failed. Turning queuing off on the account prevents this; if the setting isn't available to you, Vobiz support can disable it for you.

> **Tip**
>
> Vobiz supports [call transfer](/voice-agents/build/tools/call-transfer) end to end. No extra configuration is required on the Vobiz platform.
