Descripción

This PR adds comprehensive WhatsApp call recording and management capabilities to the Baileys provider through integration with the wavoip infrastructure.

Changes Overview

New Features

1. Call Recording Infrastructure

   • Added CallRecord interface to track call metadata (ID, caller, status, duration, timestamps)
   • Implemented call history persistence as JSON metadata files
   • Support for configurable recording formats (WAV, MP3)
   • Automatic call record directory creation and management

2. Wavoip Bridge Integration

   • Established Socket.IO connection to wavoip servers for call signaling
   • Forwarded critical Baileys methods to wavoip (onWhatsApp, profilePictureUrl, assertSessions, etc.)
   • Implemented bidirectional event forwarding for connection updates and raw call packets
   • Added proper connection lifecycle management (connect, disconnect, error handling)

3. Call Management APIs

   • rejectCall(): Programmatically reject incoming calls
   • getCallHistory(): Retrieve all saved call records from disk
   • getActiveCall(): Get info about a specific active call
   • getActiveCalls(): Get all currently active calls

4. Configuration Options

   • New callRecording config object with:
     • enabled: Toggle call recording
     • path: Custom recordings directory
     • format: Audio format preference (wav/mp3)
     • autoReject: Auto-reject incoming calls
     • wavoip: Wavoip server configuration (token, logger, softwareBase)

Technical Details

• Added socket.io-client dependency for wavoip communication
• Enhanced call event handler to track call lifecycle (offer → accept/reject/timeout → terminate)
• Implemented proper cleanup of wavoip connections on provider shutdown
• Call records include duration calculation and file path references for future audio integration

Files Modified

• package.json: Added socket.io-client dependency
• src/bailey.ts: Core implementation of wavoip bridge and call recording
• src/type.ts: New TypeScript interfaces for call recording and wavoip events
• src/index.ts: Exported new types for public API

Usage Example

const provider = new BaileysProvider({
  callRecording: {
    enabled: true,
    path: './recordings',
    format: 'wav',
    autoReject: false,
    wavoip: {
      token: 'your-wavoip-token',
      logger: true
    }
  }
})

// Get call history
const history = await provider.getCallHistory()

// Reject a call programmatically
await provider.rejectCall(callId, callFrom)

// Check active calls
const activeCalls = provider.getActiveCalls()
