# 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
|
||||
|
||||

# 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.
