# Rivet Voice Assistant - Deployment Complete ✅

**Date:** 2026-02-04
**Status:** RUNNING
**Service:** rivet-voice.service

## System Status

```
✅ Service: ACTIVE (systemd)
✅ Port: 8765 (listening on 0.0.0.0)
✅ Process: Running (PID: check with systemctl status)
✅ Logs: /home/ccuser/rateright-growth/voice-assistant/logs/
```

## What Was Built

A complete real-time voice phone AI system that connects:
1. **Twilio** (phone calls) → 
2. **Deepgram** (Australian English STT) → 
3. **Claude Opus 4.5** (conversation AI) → 
4. **ElevenLabs** (voice synthesis, "Charlie" voice) → 
5. Back to **Twilio** (caller hears response)

## Components

### 1. Main Voice Assistant (`voice_assistant.py`)
- WebSocket server on port 8765
- Handles Twilio Media Streams protocol
- Integrates Pipecat services (Deepgram, Claude, ElevenLabs)
- Conversation history management
- System prompt: "Rivet, COO of RateRight"

### 2. Outbound Call Script (`make_call.py`)
- Make calls to any number
- Automatically connects to voice assistant
- Usage: `python make_call.py +61426246472`

### 3. Systemd Service (`rivet-voice.service`)
- Auto-starts on boot
- Automatic restart on failure
- Logs to systemd journal

### 4. Environment Configuration (`.env`)
- All API keys securely stored
- Not committed to git
- Required keys: Anthropic, ElevenLabs, Deepgram, Twilio, OpenAI

## Service Management

### Start/Stop/Restart
```bash
sudo systemctl start rivet-voice
sudo systemctl stop rivet-voice
sudo systemctl restart rivet-voice
```

### Check Status
```bash
sudo systemctl status rivet-voice
```

### View Logs
```bash
# Live log stream
sudo journalctl -u rivet-voice -f

# Recent logs
sudo journalctl -u rivet-voice --since "10 minutes ago"

# File logs
tail -f /home/ccuser/rateright-growth/voice-assistant/logs/*.log
```

## Twilio Configuration

### Webhook URL
The voice assistant is accessible at:
```
ws://134.199.153.159:8765/media-stream
```

### Configure Inbound Calls

**Option 1: TwiML Bin**
1. Go to: https://console.twilio.com/us1/develop/voice/manage/twiml-bins
2. Create new TwiML Bin with:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Say voice="alice">Connecting to Rivet</Say>
    <Connect>
        <Stream url="ws://134.199.153.159:8765/media-stream"/>
    </Connect>
</Response>
```
3. Save and note the URL

**Option 2: Direct Phone Number Configuration**
1. Go to: https://console.twilio.com/us1/develop/phone-numbers/manage/incoming
2. Select: +61238205443
3. Under "Voice Configuration":
   - **A call comes in:** TwiML Bin
   - Select the TwiML Bin created above

### Configure Outbound Calls
Outbound calls use `make_call.py` which automatically includes the correct webhook.

## Making Calls

### Outbound Call to Michael
```bash
cd /home/ccuser/rateright-growth/voice-assistant
source venv/bin/activate
python make_call.py +61426246472
```

This will:
1. Call Michael's number
2. Play "Connecting to Rivet"
3. Connect to the voice assistant websocket
4. Start the AI conversation

### Inbound Calls
Once Twilio is configured:
1. Call +61238205443
2. Hear "Connecting to Rivet"
3. Get connected to the voice assistant
4. Talk to Rivet (Claude AI)

## Testing

### 1. Test Service is Running
```bash
systemctl is-active rivet-voice
# Should output: active
```

### 2. Test Port is Listening
```bash
lsof -i :8765
# Should show python process listening
```

### 3. Test Websocket Connection
```bash
# Install wscat if needed
npm install -g wscat

# Test connection
wscat -c ws://localhost:8765/media-stream
```

### 4. Make Test Call
```bash
python make_call.py +61426246472
```

## Monitoring

### Health Check Script
```bash
#!/bin/bash
# health_check.sh

if systemctl is-active --quiet rivet-voice; then
    echo "✅ Rivet Voice Assistant is RUNNING"
    lsof -i :8765 >/dev/null && echo "✅ Port 8765 is LISTENING"
else
    echo "❌ Rivet Voice Assistant is DOWN"
    exit 1
fi
```

### Add to Cron (Optional)
```bash
# Check health every 5 minutes
*/5 * * * * /home/ccuser/rateright-growth/voice-assistant/health_check.sh
```

## Troubleshooting

### Service Won't Start
```bash
# Check logs
sudo journalctl -u rivet-voice -n 50

# Check for errors
sudo journalctl -u rivet-voice --since "5 minutes ago" | grep -i error

# Test manually
cd /home/ccuser/rateright-growth/voice-assistant
source venv/bin/activate
python voice_assistant.py
```

### Port Already in Use
```bash
# Find process
sudo lsof -i :8765

# Kill if needed
sudo kill <PID>

# Restart service
sudo systemctl restart rivet-voice
```

### API Errors
- Check `.env` has all keys
- Verify Anthropic key: https://console.anthropic.com/settings/keys
- Verify ElevenLabs key: https://elevenlabs.io/app/settings/api-keys
- Verify Deepgram key: https://console.deepgram.com/
- Check Twilio credentials: https://console.twilio.com/

### Call Not Connecting
1. Check service is running: `systemctl status rivet-voice`
2. Check firewall allows port 8765:
   ```bash
   sudo ufw status
   sudo ufw allow 8765/tcp  # If blocked
   ```
3. Test websocket locally first
4. Check Twilio webhook configuration
5. Check Twilio console for call logs

## Next Steps

### Immediate
- [ ] Test inbound call to +61238205443
- [ ] Test outbound call to Michael
- [ ] Configure Twilio webhook
- [ ] Monitor logs for issues

### Future Enhancements
- [ ] Add conversation memory/context
- [ ] Integrate with Growth Engine CRM
- [ ] Add call recording
- [ ] Add analytics/metrics
- [ ] Support multiple concurrent calls
- [ ] Add voice authentication
- [ ] SMS notifications for missed calls

## Architecture Notes

### Why This Approach?
- **Pipecat**: Best framework for real-time voice AI pipelines
- **Websockets**: Direct connection with Twilio Media Streams
- **Deepgram**: Lowest latency for Australian English STT
- **Claude Opus 4.5**: Best conversation quality
- **ElevenLabs**: Best voice quality for "Rivet" persona

### Limitations
- Single conversation at a time (can be scaled)
- No conversation persistence (can be added)
- Basic error handling (can be improved)
- No call recording (can be added)

### Security Considerations
- API keys in `.env` (not in git)
- Service runs as root (consider non-root user)
- No authentication on websocket (Twilio-only access)
- No SSL/TLS (consider nginx proxy)
