+# Debugging Incoming Call Issue
+
+## Current Problem
+- Hear "Connecting to your call" message (TwiML is executing)
+- No ring on mobile after "Connecting" message
+- Click Accept button does nothing
+- Call never connects
+
+## Root Cause Hypothesis
+The Twilio Device SDK is likely **NOT receiving the incoming call event** from Twilio's Signaling Server. This could be because:
+
+1. **Identity Mismatch**: The Device's identity (from JWT token) doesn't match the `<Client>ID</Client>` in TwiML
+2. **Device Not Registered**: Device registration isn't completing before the call arrives
+3. **Twilio Signaling Issue**: Device isn't connected to Twilio Signaling Server
+
+## How to Debug
+
+### Step 1: Check Device Identity in Console
+When you open the softphone dialog, **open Browser DevTools Console (F12)**
+
+You should see logs like:
+```
+Token received, creating Device...
+Token identity: e6d45fa3-a108-4085-81e5-a8e05e85e6fb
+Token grants: {voice: {...}}
+Registering Twilio Device...
+✓ Twilio Device registered - ready to receive calls
+Device identity: e6d45fa3-a108-4085-81e5-a8e05e85e6fb
+Device state: ready
+```
+
+**Note the Device identity value** - e.g., "e6d45fa3-a108-4085-81e5-a8e05e85e6fb"
+
+### Step 2: Check Backend Logs
+When you make an inbound call, look for backend logs showing:
+
+```
+╔════════════════════════════════════════╗
+║ === INBOUND CALL RECEIVED ===
+╚════════════════════════════════════════╝
+...
+Client IDs to dial: e6d45fa3-a108-4085-81e5-a8e05e85e6fb
+First Client ID format check: "e6d45fa3-a108-4085-81e5-a8e05e85e6fb" (length: 36)
+```
+
+### Step 3: Compare Identities
+The Device identity from frontend console MUST MATCH the Client ID from backend logs.
+
+**If they match**: The issue is with Twilio Signaling or Device SDK configuration
+**If they don't match**: We found the bug - identity mismatch
+
+### Step 4: Monitor Incoming Event
+When you make the inbound call, keep watching the browser console for:
+
+```
+🔔 Twilio Device INCOMING event received: {...}
+```
+
+**If this appears**: The Device SDK IS receiving the call, so the Accept button issue is frontend
+**If this doesn't appear**: The Device SDK is NOT receiving the call, so it's an identity/registration issue
+
+## What Changed
+- Frontend now relies on **Twilio Device SDK `incoming` event** (not Socket.IO) for showing incoming call
+- Added comprehensive logging to Device initialization
+- Added logging to Accept button handler
+- Backend logs Device ID format for comparison
+
+## Next Steps
+
+1. Make an inbound call
+2. Check browser console for the 5 logs above
+3. Check backend logs for Client ID
+4. Look for "🔔 Twilio Device INCOMING event" in browser console
+5. Try clicking Accept and watch console for "📞 Accepting call" logs
+6. Report back with:
+   - Device identity from console
+   - Client ID from backend logs
+   - Whether "🔔 Twilio Device INCOMING event" appears
+   - Whether any accept logs appear
+
+## Important Files
+- Backend: `/backend/src/voice/voice.controller.ts` (lines 205-210 show Client ID logging)
+- Frontend: `/frontend/composables/useSoftphone.ts` (Device initialization and incoming handler)

+# 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

+
+# Check frontend build  
+cd frontend && npm run build
+
+# Verify migrations
+cd backend && npm run migrate:status
+
+# Test WebSocket (after starting backend)
+# In browser console:
+const socket = io('http://localhost:3000/voice', {
+  auth: { token: 'YOUR_JWT_TOKEN' }
+});
+socket.on('connect', () => console.log('Connected!'));
+```
+
+## Common Issues & Solutions
+
+| Issue | Check | Solution |
+|-------|-------|----------|
+| "Not connected" | WebSocket URL | Verify BACKEND_URL in frontend .env |
+| Build fails | Dependencies | Run `npm install` again |
+| Twilio errors | Credentials | Re-enter credentials in settings |
+| No AI features | OpenAI key | Add API key in integrations |
+| Webhook 404 | URL format | Ensure `/api/voice/...` prefix |
+| HTTPS required | Twilio webhooks | Deploy with HTTPS or use ngrok for testing |
+
+## Post-Deployment Tasks
+
+- [ ] Train users on softphone features

+# Softphone Implementation with Twilio & OpenAI Realtime
+
+## Overview
+
+This implementation adds comprehensive voice calling functionality to the platform using Twilio for telephony and OpenAI Realtime API for AI-assisted calls. The softphone is accessible globally through a Vue component, with call state managed via WebSocket connections.
+
+## Architecture
+
+### Backend (NestJS + Fastify)
+
+#### Core Components
+
+1. **VoiceModule** (`backend/src/voice/`)
+   - `voice.module.ts` - Module configuration
+   - `voice.gateway.ts` - WebSocket gateway for real-time signaling
+   - `voice.service.ts` - Business logic for call orchestration
+   - `voice.controller.ts` - REST endpoints and Twilio webhooks
+   - `dto/` - Data transfer objects for type safety
+   - `interfaces/` - TypeScript interfaces for configuration
+
+2. **Database Schema**
+   - **Central Database**: `integrationsConfig` JSON field in Tenant model (encrypted)
+   - **Tenant Database**: `calls` table for call history and metadata
+
+3. **WebSocket Gateway**
+   - Namespace: `/voice`
+   - Authentication: JWT token validation in handshake
+   - Tenant Context: Extracted from JWT payload
+   - Events: `call:initiate`, `call:accept`, `call:reject`, `call:end`, `call:dtmf`
+   - AI Events: `ai:transcript`, `ai:suggestion`, `ai:action`
+
+4. **Twilio Integration**
+   - SDK: `twilio` npm package
+   - Features: Outbound calls, TwiML responses, Media Streams, webhooks

+## Advanced Features
+
+### AI-Assisted Calling
+
+The OpenAI Realtime API provides:
+
+1. **Real-time Transcription** - Live speech-to-text during calls
+2. **AI Suggestions** - Contextual suggestions for agents
+3. **Tool Calling** - CRM actions via AI (search contacts, create tasks, etc.)
+
+### Tool Definitions
+
+The system includes predefined tools for AI:
+
+- `search_contact` - Search CRM for contacts
+- `create_task` - Create follow-up tasks
+- `update_contact` - Update contact information
+
+Tools automatically respect RBAC permissions as they call existing protected services.
+
+### Call Recording
+
+- Automatic recording via Twilio
+- Recording URLs stored in call records
+- Accessible via API for playback
+
+## Security
+
+1. **Encryption** - All credentials encrypted using AES-256-CBC
+2. **Authentication** - JWT-based auth for WebSocket and REST
+3. **Tenant Isolation** - Multi-tenant architecture with database-per-tenant
+4. **RBAC** - Permission-based access control (future: add voice-specific permissions)
+
+## Limitations & Future Enhancements
+
+### Current Limitations
+
+1. **Media Streaming** - Twilio Media Streams WebSocket not fully implemented
+2. **Call Routing** - No intelligent routing for inbound calls yet
+3. **Queue Management** - Basic call handling, no queue system
+4. **Audio Muting** - UI placeholder, actual audio muting not implemented
+5. **RBAC Permissions** - Voice-specific permissions not yet added
+
+### Planned Enhancements
+
+1. **Media Streams** - Full bidirectional audio between Twilio ↔ OpenAI ↔ User
+2. **Call Routing** - Route calls based on availability, skills, round-robin
+3. **Queue System** - Call queuing with BullMQ integration
+4. **Call Analytics** - Dashboard with call metrics and insights
+5. **RBAC Integration** - Add `voice.make_calls`, `voice.receive_calls` permissions
+6. **WebRTC** - Direct browser-to-Twilio audio (bypass backend)
+
+## Troubleshooting
+
+### WebSocket Connection Issues
+
+- Verify `BACKEND_URL` environment variable
+- Check CORS settings in backend
+- Ensure JWT token is valid and includes tenant information
+
+### Twilio Webhook Errors
+
+- Ensure webhook URLs are publicly accessible
+- Verify Twilio credentials in integrations config
+- Check backend logs for webhook processing errors
+
+### OpenAI Connection Issues
+
+- Verify OpenAI API key has Realtime API access
+- Check network connectivity to OpenAI endpoints
+- Monitor backend logs for WebSocket errors

+# Twilio Setup Guide for Softphone
+
+## Prerequisites
+- Twilio account with a phone number
+- Account SID and Auth Token
+
+## Basic Setup (Current - Makes calls but no browser audio)
+
+Currently, the softphone initiates calls through Twilio's REST API, but the audio doesn't flow through the browser. The calls go directly to your mobile device with a simple TwiML message.
+
+## Full Browser Audio Setup (Requires additional configuration)
+
+To enable actual softphone functionality where audio flows through your browser's microphone and speakers, you need:
+
+### Option 1: Twilio Client SDK (Recommended)
+
+1. **Create a TwiML App in Twilio Console**
+   - Go to https://console.twilio.com/us1/develop/voice/manage/twiml-apps
+   - Click "Create new TwiML App"
+   - Name it (e.g., "RouteBox Softphone")
+   - Set Voice URL to: `https://yourdomain.com/api/voice/twiml/outbound`
+   - Set Voice Method to: `POST`
+   - Save and copy the TwiML App SID
+
+2. **Create an API Key**
+   - Go to https://console.twilio.com/us1/account/keys-credentials/api-keys
+   - Click "Create API key"
+   - Give it a friendly name
+   - Copy both the SID and Secret (you won't be able to see the secret again)
+
+3. **Add credentials to Settings > Integrations**
+   - Account SID (from main dashboard)
+   - Auth Token (from main dashboard)
+   - Phone Number (your Twilio number)
+   - API Key SID (from step 2)
+   - API Secret (from step 2)
+   - TwiML App SID (from step 1)
+
+### Option 2: Twilio Media Streams (Alternative - More complex)
+
+Uses WebSocket to stream audio bidirectionally:
+- Requires WebSocket server setup
+- More control over audio processing
+- Can integrate with OpenAI Realtime API more easily
+
+## Current Status
+
+The system works but audio doesn't flow through browser because:
+1. Calls are made via REST API only
+2. No Twilio Client SDK integration yet
+3. TwiML returns simple voice message
+
+To enable browser audio, you need to:
+1. Complete the Twilio setup above
+2. Implement the frontend Twilio Device connection
+3. Modify TwiML to dial the browser client instead of just the phone number
+
+## Quick Test (Current Setup)
+
+1. Save your Account SID, Auth Token, and Phone Number in Settings > Integrations
+2. Click the phone icon in sidebar
+3. Enter a phone number and click "Call"
+4. You should receive a call that says "This is a test call from your softphone"
+
+The call works, but audio doesn't route through your browser - it's just a regular phone call initiated by the API.
