VOIP (Voice over Internet Protocol) is a technology for transmitting voice data over the Internet Protocol (IP). Instead of using traditional telephone lines that transmit an analog signal, VOIP converts voice to digital format and transmits it over the Internet.

The main advantage of VOIP is to reduce the cost of calls, especially internationally. Since VOIP uses Internet infrastructure rather than traditional telephone networks, the cost of calls is usually significantly reduced. Voice transmission over the Internet also allows you to use a wider range of functions and capabilities compared to traditional telephony.

VOIP also has high flexibility and mobility. Users can have conversations from anywhere in the world with Internet access, and their devices can be connected to an IP telephony system. This is especially convenient for businesses and workgroups, as it allows you to connect several remote offices through a single network.

VOIP also offers a wide range of additional features such as video conferencing, multichannel communication, call forwarding, voicemail and others. This allows you to organize effective communication and improve processes within the organization.

However, VOIP also has some limitations. Sound quality and reliability may depend on the quality of the Internet connection and network bandwidth. There is also a possible security vulnerability, there is a risk of interception and unauthorized access to voice data.

In general, VOIP technology is an efficient and cost-effective solution for voice communication. It is already widely used both in the home environment and in the business sector, and offers new opportunities for communication.
