# Telephony Provider Implementation
|
||||
|
||||
This module implements the telephony provider abstraction for Dograh AI. For user-facing documentation, see the [Mintlify docs](https://docs.dograh.com/integrations/telephony/overview).
|
||||
|
||||
## Architecture
|
||||
|
||||
```
|
||||
Business Logic → TelephonyProvider (Interface) → Concrete Provider (Twilio, Vonage, etc.)
|
||||
```
|
||||
|
||||
## Developer Quick Reference
|
||||
|
||||
### Using the Provider in Code
|
||||
|
||||
```python
|
||||
from api.services.telephony.factory import get_telephony_provider
|
||||
|
||||
# Get provider based on organization config
|
||||
provider = await get_telephony_provider(organization_id)
|
||||
|
||||
# Initiate a call
|
||||
result = await provider.initiate_call(
|
||||
to_number="+1987654321",
|
||||
webhook_url="https://your-app.com/webhook",
|
||||
workflow_run_id=123
|
||||
)
|
||||
```
|
||||

||||

|
||||
|
||||
## Implementing a New Provider
|
||||
|
||||
See the [Custom Provider Guide](https://docs.dograh.com/integrations/telephony/custom) in the documentation for detailed implementation instructions.
|
||||
|
||||
Quick checklist:
|
||||
1. Create `providers/your_provider.py` implementing `TelephonyProvider`
|
||||
2. Update `factory.py` to include your provider
|
||||
3. Write unit tests
|
||||
4. Update documentation
|
||||
|
||||
## Key Interfaces
|
||||
|
||||
```python
|
||||
class TelephonyProvider(ABC):
|
||||
@abstractmethod
|
||||
async def initiate_call(self, to_number: str, webhook_url: str, workflow_run_id: Optional[int] = None, **kwargs: Any) -> Dict[str, Any]
|
||||
|
||||
@abstractmethod
|
||||
async def get_call_status(self, call_id: str) -> Dict[str, Any]
|
||||
|
||||
@abstractmethod
|
||||
async def get_available_phone_numbers(self) -> List[str]
|
||||
|
||||
@abstractmethod
|
||||
def validate_config(self) -> bool
|
||||
|
||||
@abstractmethod
|
||||
async def verify_webhook_signature(self, url: str, params: Dict[str, Any], signature: str) -> bool
|
||||
|
||||
@abstractmethod
|
||||
async def get_webhook_response(self, workflow_id: int, user_id: int, workflow_run_id: int) -> str
|
||||
```
|
||||
|
||||
## Configuration Loading
|
||||
|
||||
The `factory.py` loads configuration from the database:
|
||||
|
||||
**Both Saas and OSS Modes**: Database configuration via UI
|
||||
```python
|
||||
# Loaded from organization_configuration table
|
||||
key: "TELEPHONY_CONFIGURATION"
|
||||
value: {
|
||||
"provider": "twilio", # or "vonage"
|
||||
"account_sid": "xxx", # for Twilio
|
||||
"auth_token": "xxx", # for Twilio
|
||||
"application_id": "xxx", # for Vonage
|
||||
"private_key": "xxx", # for Vonage
|
||||
"from_numbers": [...]
|
||||
}
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
### Unit Testing with Mock Provider
|
||||
|
||||
```python
|
||||
class MockProvider(TelephonyProvider):
|
||||
async def initiate_call(self, to_number, webhook_url, **kwargs):
|
||||
return {"call_id": "mock_123", "status": "initiated"}
|
||||
|
||||
async def get_call_status(self, call_id):
|
||||
return {"call_id": call_id, "status": "completed"}
|
||||
|
||||
# Implement other required methods...
|
||||
|
||||
# In tests
|
||||
@patch('api.services.telephony.factory.get_telephony_provider')
|
||||
async def test_call_initiation(mock_get_provider):
|
||||
mock_get_provider.return_value = MockProvider()
|
||||
# Test your business logic
|
||||
```
|
||||
|
||||
### Integration Testing
|
||||
|
||||
Run against actual providers in development:
|
||||
|
||||
1. Configure your provider through the UI:
|
||||
- Navigate to Settings → Integrations → Telephony
|
||||
- Select your provider (Twilio or Vonage)
|
||||
- Enter test credentials
|
||||
- Save configuration
|
||||
|
||||
2. Run integration tests:
|
||||
```bash
|
||||
pytest tests/integration/test_telephony.py
|
||||
```
|
||||
|
||||
## Migration Notes
|
||||
|
||||
### From Direct TwilioService Usage
|
||||
|
||||
Old code:
|
||||
```python
|
||||
from api.services.telephony.twilio import TwilioService
|
||||
service = TwilioService(org_id)
|
||||
await service.initiate_call(...)
|
||||
```
|
||||
|
||||
New code:
|
||||
```python
|
||||
from api.services.telephony.factory import get_telephony_provider
|
||||
provider = await get_telephony_provider(org_id)
|
||||
await provider.initiate_call(...)
|
||||
```
|
||||
|
||||
### Backward Compatibility
|
||||
|
||||
- Old `/api/v1/twilio/*` endpoints still work (redirect to `/api/v1/telephony/*`)
|
||||
- `TwilioService` class remains for legacy code
|
||||
- Database configuration key `TWILIO_CONFIGURATION` unchanged
|
||||
|
||||
## Common Issues
|
||||
|
||||
1. **Import Error**: Always import from `factory`, not directly from providers
|
||||
2. **Config Not Found**: Check database configuration via UI
|
||||
3. **Signature Verification**: Ensure auth tokens match between provider and config
|
||||
4. **WebSocket Issues**: Verify audio format compatibility (MULAW for Twilio)
