VoIP, or Voice over Internet Protocol, is a comprehensive methodology and collection of technologies designed to facilitate the transmission of voice communications and multimedia sessions over Internet Protocol (IP) networks.

This innovative approach allows users to make voice calls using a broadband Internet connection instead of a traditional analog phone line. VoIP converts voice signals into digital data packets, which are then transmitted over the internet or other IP-based networks.

This technology supports a wide range of communication services, including voice calls, video calls, and conferencing, as well as the integration of various multimedia elements such as text, images, and video. VoIP is widely used in both personal and business settings due to its cost-effectiveness, flexibility, and the ability to integrate with other internet services.

It enables features such as call forwarding, voicemail, caller ID, and call waiting, often at a lower cost than traditional telephony services. Additionally, VoIP can be used on various devices, including computers, smartphones, and dedicated VoIP phones, making it a versatile solution for modern communication needs.
