## Overview

Vobiz is a cloud-based telephony service provider that offers global reach with competitive pricing. Dograh AI's Vobiz integration provides reliable voice connectivity for your conversational AI agents.

## Prerequisites

Before setting up Vobiz integration, you'll need:

- A [Vobiz account](https://vobiz.com)
- Auth ID and Auth Token from your Vobiz dashboard
- A Vobiz **Application** (used for inbound webhook routing)
- At least one Vobiz phone number
- Dograh AI instance running and accessible

## Configuration

### Step 1: Get Vobiz Credentials

1. Log in to your Vobiz dashboard
2. Find your **Auth ID** and generate an **Auth Token** for API access
3. Navigate to the **Applications** section and create (or open) the application you'll use with Dograh
4. Copy the **Application ID** — Dograh will manage its `answer_url`
5. Navigate to **Phone Numbers** and copy the numbers you plan to use

### Step 2: Configure in Dograh AI

1. Navigate to **/telephony-configurations** and click **Add configuration**
2. Select **Vobiz** as your provider
3. Enter your credentials:
   - Auth ID
   - Auth Token
   - Application ID
4. Click **Save Configuration**
5. Open the configuration you just created and add at least one **phone number** (with country code in E.164 format, e.g. `+1234567890`). The default caller ID is used for outbound calls.

### Step 3: Test Your Configuration

1. Create a test workflow
2. Click "Call" to verify connection
3. Check call logs for successful connection

## Inbound Calling Setup

Vobiz numbers don't carry an `answer_url` directly — the URL lives on a Vobiz **Application**, and each number is linked to one application. **When you save an inbound workflow on a phone number, Dograh automatically pushes the webhook URL to your Vobiz Application's `answer_url`** (provided the credentials are correct).

### Step 1: Link the Phone Number to Your Vobiz Application

1. Log in to your Vobiz Console and open the **Applications** section
2. Edit the application whose ID you configured in Dograh
3. Attach the phone number you want to use for inbound calls
4. Save

     alt="Vobiz application showing phone number attachment interface"
   />
   <img
     className="hidden dark:block"
     src="/images/vobiz-inbound-config-3.png"
     alt="Vobiz application showing phone number attachment interface"
   />

### Step 2: Assign an Inbound Workflow to the Phone Number in Dograh

1. Go to **/telephony-configurations** and open your Vobiz configuration
2. In the **Phone numbers** section, edit the number that should receive inbound calls
3. Set its **Inbound workflow** to the agent that should answer
4. Save

### Step 3: Verify the Answer URL on the Vobiz Application

1. Open your Vobiz Console and navigate to **Applications**
2. Open the application whose ID you configured in Dograh
3. Confirm:
   - **Answer URL** is set to: `https://api.dograh.com/api/v1/telephony/inbound/run`
   - **Answer Method** is `POST`

   <Note>
     Dograh pushed this URL automatically when you saved the inbound workflow
     in Step 2. The same URL is shared across every number linked to that
     application — Dograh routes each inbound call to the right agent based
     on the called number's inbound workflow assignment. If the field is
     empty, shows a different URL, or Dograh surfaced a sync warning on
     save, the auto-push failed — most often because the Auth ID/Token or
     Application ID in Dograh is incorrect. Paste the URL into the field
     yourself, set the method to `POST`, and save. On self-hosted Dograh,
     replace `api.dograh.com` with your backend domain.
   </Note>

### Step 4: Verify Setup

- Ensure your Dograh AI instance is publicly accessible
- Verify any firewalls allow Vobiz's webhook requests

### Test Inbound Calling

1. Call your configured Vobiz phone number from another phone
2. Verify your Dograh AI voice agent answers and responds
3. Check call logs in both Dograh AI dashboard and Vobiz dashboard

## Troubleshooting

<AccordionGroup>
  <Accordion title="Invalid phone number error">
    Ensure phone numbers include country code in E.164 format: `+1234567890`
  </Accordion>
  
  <Accordion title="Authentication failed">
    - Verify Auth ID and Auth Token are correct
    - Check for extra spaces in credentials
    - Ensure credentials haven't been regenerated in Vobiz dashboard
  </Accordion>
  
  <Accordion title="Webhook requests failing">
    - Confirm your Auth Token matches exactly
    - Verify the webhook URL is accessible from Vobiz servers
    - Check if you're behind a proxy that modifies requests
  </Accordion>
  
  <Accordion title="No audio on calls">
    - Verify WebSocket connection is established
    - Check firewall rules for WebSocket traffic
    - Ensure audio pipeline is configured correctly
  </Accordion>
  
  <Accordion title="Inbound calls go to voicemail or aren't answered">
    - Verify the phone number is linked to the same Vobiz Application whose
    ID you configured in Dograh - Confirm the called number exists in your
    Dograh telephony configuration and has an **Inbound workflow** assigned
    - After assigning the inbound workflow, confirm Dograh successfully
    updated the application's `answer_url` (no warning shown on save) -
    Verify Dograh AI instance is running and responding
  </Accordion>

  <Accordion title="Voice agent doesn't respond to inbound calls">
    - Confirm the phone number has an **Inbound workflow** assigned in
    /telephony-configurations - Check webhook signature validation is working
    (Auth Token in Dograh matches Vobiz dashboard) - Verify WebSocket connection
    establishes successfully - Review call logs for error messages
  </Accordion>
</AccordionGroup>

## Best Practices

- Test your configuration with a single call before running campaigns
- Monitor Vobiz dashboard for usage and billing
- Keep your Auth Token secure and rotate it periodically
- Use a dedicated Vobiz Application for Dograh so the shared `answer_url` doesn't conflict with other systems
