Session Initiation Protocol (SIP) is a signaling protocol used to initiate, maintain, modify, and terminate real-time communication sessions involving video, voice, messaging, and other communications applications. It operates predominantly in the application layer of the Internet Protocol Suite and is essential for facilitating the setup and management of multimedia communication sessions over IP networks.

Video communication

Voice communication is the transmission of spoken information between parties and is fundamental to human interaction, leveraging both verbal and non-verbal cues to convey messages effectively. It encompasses various technologies and methods, from traditional telephony to modern digital platforms, enabling real-time, clear, and efficient exchanges across distances.

The Application Layer is the topmost layer in the OSI model, responsible for facilitating communication between software applications and ensuring that they can effectively use network services. It provides protocols and services that directly support user applications, such as web browsers and email clients, enabling them to interpret and present data to end-users.

The Internet Protocol Suite, commonly known as TCP/IP, is the fundamental set of communication protocols used for the Internet and similar networks, enabling diverse devices to connect and exchange data. It organizes data transmission into layers, with each layer serving specific functions, ensuring reliable and efficient communication across interconnected networks.

IP Networks are a fundamental component of the internet, enabling the routing of data packets between devices using the Internet Protocol (IP). They ensure efficient communication by assigning unique IP addresses to each device and using routers to direct data along optimal paths to its destination.
