SIP-MCPTT-Core

# MCX-SIP-Comm ## Overview MCX-SIP-Comm is a **mission-critical communication system** built with **SIP (Session Initiation Protocol)** and **MCPTT (Mission-Critical Push-to-Talk)** technologies to ensure **secure, real-time voice communication** in high-reliability environments. This system is designed to provide **encrypted, concurrent, and scalable** communication, ideal for mission-critical applications that require the highest levels of reliability and security. ## Key Features - **SIP-based signaling**: Handles call setup, session management, and signaling using the robust SIP protocol. - **MCPTT functionality**: Implements Mission-Critical Push-to-Talk (MCPTT) for instant, reliable voice communication in high-stakes environments. - **End-to-end encryption**: Utilizes **TLS** for signaling security and **SRTP** for encrypted media, ensuring communication confidentiality. - **Multithreaded processing**: Uses **POSIX pthreads** to manage multiple concurrent calls, maximizing performance and responsiveness. - **Efficient session management**: Implements advanced **data structures** such as **linked lists**, **structs**, **enums**, and **unions** for optimal session management and scalability. - **Automated QA framework**: Includes a custom **QA automation suite** for functional and stress testing to ensure system reliability under heavy load conditions. ## Technologies & Tools Used - **SIP Stack**: Sofia-SIP, a robust open-source SIP stack. - **Multithreading**: POSIX **pthreads** for handling concurrent communications. - **Security**: **TLS** for signaling encryption, **SRTP** for media encryption. - **Programming Language**: C, leveraging low-level system capabilities for optimal performance. - **Data Structures**: Advanced use of **structs**, **enums**, **unions**, and **linked lists** for highly efficient and scalable session management. - **Testing Framework**: Custom-built automation tools for functional and stress testing. - **Docker**: Integrated Docker support to build and run the system in a containerized environment, eliminating the need for `sudo` or system-wide installations and dependencies. ## Roles - **Developer**: Responsible for implementing SIP signaling, media handling, and session management, with a focus on security and performance. - **QA Engineer**: Develops testing strategies, creates automated test scripts, and ensures the system's reliability under varying loads. ## Installation Guide 1. **Clone the Repository** Clone the repository to your local machine: ```sh git clone https://github.com/your-repo/MCX-SIP-Comm.git cd MCX-SIP-Comm 2. **Build with Docker** The project includes a Docker configuration to build the system with all dependencies pre-configured (including Sofia-SIP, OpenSSL, etc.), ensuring a smooth setup without the need for sudo or system-wide installations. ```sh make 3. **Run the application** Once the build completes, you can run the SIP server and client: ```sh # Start the SIP server ./mcx_sip_server # Start a client ./mcx_sip_client -u user1 -p 5060 ## Contributors - Vanessa Lorenzo Toquero – Developer & QA - César M.
