# 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**

## 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
