Technical Architecture
The TextFree system consists of multiple components that ensure smooth communication:
1. Backend Infrastructure

- SIP (Session Initiation Protocol): This protocol initiates, maintains, and terminates VoIP calls.
- WebRTC: Enables real-time audio and video communication over web-based platforms.
- Encryption and Security: Uses TLS/SSL protocols to protect user data during transmission.
2. Client-Side Application
The mobile and web applications interact with the backend via APIs to send/receive messages and handle VoIP calls. Features include:
- Push Notifications: Utilizes Firebase Cloud Messaging (FCM) or Apple Push Notification Service (APNs) for real-time message alerts.
- Local Storage: Saves message history for offline access.
- User Authentication: Supports OAuth or social login mechanisms for secure access.
