+# Softphone AI Assistant - Complete Implementation
+
+## 🎉 Features Implemented
+
+### ✅ Real-time AI Call Assistant
+- **OpenAI Realtime API Integration** - Listens to live calls and provides suggestions
+- **Audio Streaming** - Twilio Media Streams fork audio to backend for AI processing
+- **Real-time Transcription** - Speech-to-text during calls
+- **Smart Suggestions** - AI analyzes conversation and advises the agent
+
+## 🔧 Architecture
+
+### Backend Flow
+```
+Inbound Call → TwiML (<Start><Stream> + <Dial>) 
+→ Media Stream WebSocket → OpenAI Realtime API 
+→ AI Processing → Socket.IO → Frontend
+```
+
+### Key Components
+
+1. **TwiML Structure** (`voice.controller.ts:226-234`)
+   - `<Start><Stream>` - Forks audio for AI processing
+   - `<Dial><Client>` - Connects call to agent's softphone
+
+2. **OpenAI Integration** (`voice.service.ts:431-519`)
+   - WebSocket connection to `wss://api.openai.com/v1/realtime?model=gpt-4o-realtime-preview-2024-10-01`
+   - Session config with custom instructions for agent assistance
+   - Handles transcripts and generates suggestions
+
+3. **AI Message Handler** (`voice.service.ts:609-707`)
+   - Processes OpenAI events (transcripts, suggestions, audio)
+   - Routes suggestions to frontend via Socket.IO
+   - Saves transcripts to database
+
+4. **Voice Gateway** (`voice.gateway.ts:272-289`)
+   - `notifyAiTranscript()` - Real-time transcript chunks
+   - `notifyAiSuggestion()` - AI suggestions to agent
+
+### Frontend Components
+
+1. **Softphone Dialog** (`SoftphoneDialog.vue:104-135`)
+   - AI Assistant section with badge showing suggestion count
+   - Color-coded suggestions (blue=response, green=action, purple=insight)
+   - Animated highlight for newest suggestion
+
+2. **Softphone Composable** (`useSoftphone.ts:515-535`)
+   - Socket.IO event handlers for `ai:suggestion` and `ai:transcript`
+   - Maintains history of last 10 suggestions
+   - Maintains history of last 50 transcript items
+
+## 📋 AI Prompt Configuration
+
+The AI is instructed to:
+- **Listen, not talk** - It advises the agent, not the caller
+- **Provide concise suggestions** - 1-2 sentences max
+- **Use formatted output**:
+  - `💡 Suggestion: [advice]`
+  - `⚠️ Alert: [important notice]`
+  - `📋 Action: [CRM action]`
+
+## 🎨 UI Features
+
+### Suggestion Types
+- **Response** (Blue) - Suggested replies or approaches
+- **Action** (Green) - Recommended CRM actions
+- **Insight** (Purple) - Important alerts or observations
+
+### Visual Feedback
+- Badge showing number of suggestions
+- Newest suggestion pulses for attention
+- Auto-scrolling suggestion list
+- Timestamp on each suggestion
+
+## 🔍 How to Monitor
+
+### 1. Backend Logs
+```bash
+# Watch for AI events
+docker logs -f neo-backend-1 | grep -E "AI|OpenAI|transcript|suggestion"
+```
+
+Key log markers:
+- `📝 Transcript chunk:` - Real-time speech detection
+- `✅ Final transcript:` - Complete transcript saved
+- `💡 AI Suggestion:` - AI-generated advice
+
+### 2. Database
+```sql
+-- View call transcripts
+SELECT call_sid, ai_transcript, created_at 
+FROM calls 
+ORDER BY created_at DESC 
+LIMIT 5;
+```
+
+### 3. Frontend Console
+- Open browser DevTools Console
+- Watch for: "AI suggestion:", "AI transcript:"
+
+## 🚀 Testing
+
+1. **Make a test call** to your Twilio number
+2. **Accept the call** in the softphone dialog
+3. **Talk during the call** - Say something like "I need to schedule a follow-up"
+4. **Watch the UI** - AI suggestions appear in real-time
+5. **Check logs** - See transcription and suggestion generation
+
+## 📊 Current Status
+
+✅ **Working**:
+- Inbound calls ring softphone
+- Media stream forks audio to backend
+- OpenAI processes audio (1300+ packets/call)
+- AI generates suggestions
+- Suggestions appear in frontend
+- Transcripts saved to database
+
+## 🔧 Configuration
+
+### Required Environment Variables
+```env
+# OpenAI API Key (set in tenant integrations config)
+OPENAI_API_KEY=sk-...
+
+# Optional overrides
+OPENAI_MODEL=gpt-4o-realtime-preview-2024-10-01
+OPENAI_VOICE=alloy
+```
+
+### Tenant Configuration
+Set in Settings > Integrations:
+- OpenAI API Key
+- Model (optional)
+- Voice (optional)
+
+## 🎯 Next Steps (Optional Enhancements)
+
+1. **CRM Tool Execution** - Implement actual tool calls (search contacts, create tasks)
+2. **Audio Response** - Send OpenAI audio back to caller (two-way AI interaction)
+3. **Sentiment Analysis** - Track call sentiment in real-time
+4. **Call Summary** - Generate post-call summary automatically
+5. **Custom Prompts** - Allow agents to customize AI instructions per call type
+
+## 🐛 Troubleshooting
+
+### No suggestions appearing?
+1. Check OpenAI API key is configured
+2. Verify WebSocket connection logs show "OpenAI Realtime connected"
+3. Check frontend Socket.IO connection is established
+4. Verify user ID matches between backend and frontend
+
+### Transcripts not saving?
+1. Check tenant database connection
+2. Verify `calls` table has `ai_transcript` column
+3. Check logs for "Failed to update transcript" errors
+
+### OpenAI connection fails?
+1. Verify API key is valid
+2. Check model name is correct
+3. Review WebSocket close codes in logs
