app.post('/webhook', (req, res) => {
  const { event, payload } = req.body;
  
  if (event.startsWith('qss.')) {
    // Process QSS data
    const { meeting_id, participant_id, metrics } = payload;
    
    // Send to your monitoring dashboard
    dashboard.ingest({
      meetingId: meeting_id,
      participantId: participant_id,
      bitrate: metrics.bitrate,
      latency: metrics.latency,
      jitter: metrics.jitter,
      packetLoss: metrics.packet_loss
    });
  }
  
  res.status(200).send();
});
```

## Use Cases

| Use Case | Description |
|----------|-------------|
| **Network monitoring** | Track network quality across organization |
| **Troubleshooting** | Diagnose call quality issues in real-time |
| **Capacity planning** | Understand bandwidth usage patterns |
| **SLA compliance** | Monitor meeting quality for SLA reporting |
| **Proactive alerts** | Alert IT when quality degrades |
