+description: "Configure inbound calling for Twilio, Vonage, and Cloudonix providers in Dograh AI"
+---
+
+## Overview
+
+Dograh AI supports inbound calling across all supported telephony providers. When someone calls your configured phone number, your voice agent automatically answers and handles the interaction. The inbound calling configuration in Dograh AI uses the same telephony settings as outbound calling.
+
+## Supported Providers for Inbound Calls
+
+<CardGroup cols={3}>
+  <Card title="Twilio" href="/integrations/telephony/twilio">
+    Industry-leading platform with robust inbound call handling
+  </Card>

+  <Card title="Vobiz" href="/integrations/telephony/vobiz">
+    Cloud-based telephony with global reach and competitive pricing
+  </Card>
+</CardGroup>
+
+<Note>
+**Vonage**: Inbound calling support is coming soon. Currently supports outbound calling only.
+</Note>
+
+## How Inbound Calling Works
+
+When someone calls your configured phone number:
+
+1. **Call Received**: The telephony provider receives the incoming call
+2. **Webhook Triggered**: The provider sends a webhook to Dograh AI
+3. **Agent Activated**: Dograh AI activates your configured voice agent workflow
+4. **Audio Streaming**: Real-time audio streams between caller and agent via WebSocket
+5. **Conversation Handled**: Your voice agent manages the entire conversation
+
+## Configuration in Dograh AI
+
+Setting up inbound calling requires three simple steps:
+
+### Step 1: Configure Telephony Provider
+
+The telephony configuration for inbound calling is **identical** to outbound calling. Follow the **Configuration** section in your provider's documentation page:
+
+- [Twilio Configuration](/integrations/telephony/twilio#configuration)
+- [Cloudonix Configuration](/integrations/telephony/cloudonix#configuration)
+- [Vobiz Configuration](/integrations/telephony/vobiz#configuration)
+
+### Step 2: Get Your Workflow Webhook URL
+
+1. **Find Your Workflow ID**: 
+   - Navigate to your workflow page (e.g., `https://app.dograh.com/workflow/3`)
+   - Note the workflow ID from the URL (in this example: `3`)
+
+2. **Construct Webhook URL**:
+   ```
+   https://api.dograh.com/api/v1/telephony/inbound/{workflow_id}
+   ```
+   
+   For example, if your workflow ID is `3`:
+   ```
+   https://api.dograh.com/api/v1/telephony/inbound/3
+   ```
+
+   <Note>
+   If you're using a self-hosted Dograh instance, replace `api.dograh.com` with your own domain.
+   </Note>
+
+### Step 3: Configure Provider-Specific Inbound Settings
+
+Each telephony provider requires additional configuration to route incoming calls to your Dograh AI webhook. Follow the provider-specific inbound setup instructions:
+
+- [Twilio Inbound Setup](/integrations/telephony/twilio#inbound-calling-setup)
+- [Vonage Inbound Setup](/integrations/telephony/vonage#inbound-calling-setup)
+- [Cloudonix Inbound Setup](/integrations/telephony/cloudonix#inbound-calling-setup)
+- [Vobiz Inbound Setup](/integrations/telephony/vobiz#inbound-calling-setup)
+
+
+## Testing Inbound Calls
+
+After completing both the Dograh AI configuration and provider-specific setup:
+
+1. **Test Call**: Call your configured phone number from another phone
+2. **Verify Connection**: Ensure your voice agent answers and responds appropriately
+3. **Check Logs**: Monitor call logs in both Dograh AI and your provider's dashboard
+4. **Audio Quality**: Verify clear two-way audio communication

+
+## Best Practices
+
+- **Single Configuration**: Use the same telephony configuration for both inbound and outbound calls
+- **Testing**: Always test inbound calling after configuration changes
+- **Monitoring**: Monitor both Dograh AI logs and provider dashboards for call analytics
+- **Backup Numbers**: Configure multiple phone numbers for redundancy
+- **Security**: Ensure webhook signature verification is enabled for security

+## Next Steps
+
+1. Choose your telephony provider and complete the basic configuration
+2. Follow the provider-specific setup instructions (to be detailed)
+3. Test your inbound calling setup
+4. Configure your voice agent workflow for optimal caller experience

+- 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

-## How It Works
+## Inbound Calling
 
-### Technical Details
+<Note>
+**Coming Soon**: Inbound calling support for Vonage is currently under development and will be available in a future release. For now, Vonage integration supports outbound calling only.
+</Note>
 
-Vonage integration differs from other providers in key ways:
+Vonage integration currently supports outbound calling. Inbound calling functionality is being developed and will include:
 
-- **Audio Format**: Uses 16kHz Linear PCM (vs Twilio's 8kHz μ-law)
-- **Protocol**: NCCO (Nexmo Call Control Objects) instead of TwiML
-- **Authentication**: JWT-based authentication using private keys
-- **WebSocket**: Binary audio frames instead of base64-encoded
+- Webhook configuration for incoming calls
+- NCCO response handling
+- Event tracking for call lifecycle management
+- WebSocket audio streaming for inbound calls
 
-### Call Flow
-
-1. Dograh AI generates a JWT token using your private key
-2. Call is initiated via Vonage Voice API
-3. Vonage requests NCCO instructions at the webhook URL
-4. Dograh returns WebSocket connection details
-5. Audio streams as 16kHz PCM over WebSocket
-6. Real-time voice interaction occurs with your agent
-
-### NCCO Response Example
-
-```json
-[
-  {
-    "action": "connect",
-    "endpoint": [{
-      "type": "websocket",
-      "uri": "wss://your-domain/api/v1/telephony/ws/123/456/789",
-      "content-type": "audio/l16;rate=16000",
-      "headers": {}
-    }]
-  }
-]
-```
-
-## Campaign Features
-
-When using Vonage with campaigns:
-- **Global Reach**: Excellent international call quality and coverage
-- **Number Pool Management**: Automatic rotation of configured numbers
-- **Call Analytics**: Detailed metrics via Vonage Dashboard
-- **Cost Tracking**: Per-call cost calculation for billing
+For inbound calling needs, consider using [Twilio](/integrations/telephony/twilio), [Cloudonix](/integrations/telephony/cloudonix), or [Vobiz](/integrations/telephony/vobiz) which have full inbound support.
