The system includes a Hono.js webhook server that:

- **Receives real-time callbacks** from Bland.ai when calls complete
- **Processes IVR responses** automatically (Press 1/2 handling)
- **Sends SMS messages** with Calendly links for interested prospects
- **Manages do-not-call lists** for opt-outs
- **Generates analytics** and call statistics
- **Logs all call outcomes** to JSON files

#### Webhook Endpoints

- `POST /webhook` - Main Bland.ai callback endpoint
- `GET /health` - Health check
- `GET /logs` - Retrieve call logs
- `GET /stats` - Get call statistics
- `DELETE /logs` - Clear logs (testing)

### Voice Campaign Analytics

Track comprehensive metrics:

- **Answer Rate**: Percentage of calls answered
- **Conversion Rate**: Percentage who pressed 1 (interested)
- **Opt-out Rate**: Percentage who pressed 2
- **Average Call Duration**: Mean call length
- **Campaign ROI**: Cost per interested prospect

Example analytics output:
```json
{
  "total": 100,
  "answered": 65,
  "scheduledMeetings": 12,
  "optedOut": 8,
  "answerRate": "65.00%",

## Troubleshooting

### Common Issues

**"Mailgun API key is required"**
- Ensure `MAILGUN_API_KEY` is set in your `.env` file
- Verify the API key is correct in your Mailgun dashboard

**"No valid leads found"**
- Check your CSV file format
- Ensure required columns (`FirstName`, `Company`) are present
- Verify at least one email field (`WorkEmail` or `PersonalEmail`) has valid data

**"Rate limit exceeded"**
- Increase the delay between batches with `--delay` option
- Reduce batch size with `--batch-size` option
- Check your Mailgun sending limits

**AI personalization fails**
- Verify `OPENAI_API_KEY` is set correctly
- Check your OpenAI account has sufficient credits
- Use `--ai-personalization false` to disable AI features

### Debug Mode
