## Configuration Loading
The `factory.py` handles configuration from two sources:
The `factory.py` loads configuration from the database:
1. **OSS Mode** (default): Environment variables
```python
TELEPHONY_PROVIDER=twilio
TWILIO_ACCOUNT_SID=xxx
TWILIO_AUTH_TOKEN=xxx
TWILIO_FROM_NUMBER=+1234567890
```
2. **SaaS Mode**: Database configuration per organization
**Both Saas and OSS Modes**: Database configuration via UI

# Loaded from organization_configuration table
key: "TWILIO_CONFIGURATION"
value: {"account_sid": "xxx", "auth_token": "xxx", "from_numbers": [...]}
key: "TELEPHONY_CONFIGURATION"
value: {

1. Configure your provider through the UI:
- Navigate to Settings → Integrations → Telephony

- Enter test credentials
- Save configuration

1. **Import Error**: Always import from `factory`, not directly from providers
2. **Config Not Found**: Check environment variables or database configuration
2. **Config Not Found**: Check database configuration via UI
3. **Signature Verification**: Ensure auth tokens match between provider and config

## Reference Implementations
See the Twilio provider implementation at `api/services/telephony/providers/twilio_provider.py` for a complete example.
See these provider implementations for complete examples:
- **Twilio**: `api/services/telephony/providers/twilio_provider.py` - Basic authentication, XML (TwiML) responses
- **Vonage**: `api/services/telephony/providers/vonage_provider.py` - JWT authentication, JSON (NCCO) responses
<Note>
Other providers like Plivo, Telnyx, or custom SIP providers can be implemented following the same pattern.
These are not included out-of-the-box but can be easily added by implementing the TelephonyProvider interface.

title: "Vonage Integration"
description: "Configure Vonage (Nexmo) for voice communication in Dograh AI"
---
## Overview
Vonage (formerly Nexmo) is a cloud communications platform that provides global voice, messaging, and video capabilities. Dograh AI's Vonage integration enables high-quality voice interactions with your agents using Vonage's robust infrastructure.
## Prerequisites
Before setting up Vonage integration, you'll need:
- A [Vonage account](https://www.vonage.com/communications-apis/)
- Vonage Application with Voice capability enabled
- Application ID and Private Key from your Vonage Dashboard
- At least one Vonage phone number
- Dograh AI instance running and accessible
## Configuration
### Step 1: Create Vonage Application
1. Log in to your [Vonage Dashboard](https://dashboard.nexmo.com/)
2. Navigate to **Applications** → **Create a new application**
3. Enable **Voice** capability
4. Generate a private key (save this securely - you'll need it)
5. Note your **Application ID**
### Step 2: Get API Credentials
1. Find your **API Key** and **API Secret** in the dashboard
2. Navigate to **Numbers** → **Your Numbers**
3. Copy your phone number(s)
4. Link your numbers to your application
### Step 3: Configure in Dograh AI
1. Navigate to **Settings** → **Integrations** → **Telephony**
2. Select **Vonage** as your provider
3. Enter your credentials:
- Application ID
- Private Key (entire key including BEGIN/END lines)
- API Key
- API Secret
- Phone Numbers (comma-separated if multiple)
4. Click **Test Connection**
5. Save configuration
### Step 4: Test Your Configuration
1. Create a test workflow
2. Click "Test Call" to verify connection
3. Check call logs for successful connection
## How It Works
### Technical Details
Vonage integration differs from other providers in key ways:
- **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
### 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
## Audio Quality Optimization
Vonage uses higher quality audio (16kHz) which provides:
- Clearer voice reproduction
- Better speech recognition accuracy
- More natural-sounding TTS output
- Reduced transcription errors
## Troubleshooting
<AccordionGroup>
<Accordion title="Voice application capabilities error">
- Ensure "Voice" is enabled in your Vonage application
- Verify the application ID matches your configuration
- Check that your phone numbers are linked to the application
</Accordion>
<Accordion title="JWT authentication failed">
- Verify your private key is complete (including BEGIN/END lines)
- Check the Application ID is correct
- Ensure the private key hasn't been regenerated in Vonage Dashboard
</Accordion>
<Accordion title="Invalid phone number error">
- Remove the '+' prefix for Vonage (use `1234567890` not `+1234567890`)
- Ensure numbers are in E.164 format without the '+'
- Verify numbers are active in your Vonage account
</Accordion>
<Accordion title="No audio on calls">
- Verify WebSocket connection is established
- Check audio pipeline is configured for 16kHz PCM
- Monitor WebSocket for binary audio frames
- Review VAD (Voice Activity Detection) settings
</Accordion>
<Accordion title="Calls disconnecting early">
- Check WebSocket heartbeat/ping-pong frames
- Verify no timeout in load balancer/proxy
- Monitor for audio pipeline errors
- Review max call duration settings
</Accordion>
</AccordionGroup>
## Best Practices
- **Security**: Private keys are stored securely in the database
- **Testing**: Use Vonage Voice Inspector for debugging call issues
- **Numbers**: Configure multiple numbers for redundancy
- **Monitoring**: Set up alerts in Vonage Dashboard for failures
- **Cost Management**: Monitor usage to control costs
## Cost Considerations
Vonage pricing includes:
- Per-minute charges for calls
- Phone number rental fees
- Optional features (recording, transcription)
Check [Vonage pricing](https://www.vonage.com/communications-apis/voice/pricing/) for current rates.
## Advanced Configuration
### Custom Headers
Add custom headers to WebSocket connections:
```python
# In your webhook response
"headers": {
"X-Custom-Header": "value",
"Authorization": "Bearer token"
}
```
### Call Recording
Enable call recording via NCCO:
```json
{
"action": "record",
"eventUrl": ["https://your-domain/recording-webhook"],
"format": "mp3"
}
```
## API Differences from Twilio
| Feature | Twilio | Vonage |
|---------|---------|---------|
| Audio Format | 8kHz μ-law | 16kHz Linear PCM |
| Control Format | TwiML (XML) | NCCO (JSON) |
| Authentication | Basic Auth | JWT |
| WebSocket Data | Base64 text | Binary frames |
| Phone Format | With '+' | Without '+' |
## Next Steps
- Test your Vonage integration with a simple workflow
- Configure VAD settings for optimal voice detection
- Set up monitoring and alerts
- Explore advanced features like call recording

2. Passes them to the telephony provider when initiating calls
3. Verifies webhook signatures for security
3. Verifies webhook signatures for security:
