What is VoIP and How Does It Work?

VoIP, an abbreviation for Voice over Internet Protocol, is nothing less than a revolution in digital communication. This advanced technology allows users to make voice calls over the Internet instead of conventional telephone networks. By converting voice signals into digital data packets, VoIP makes it possible to make calls from anywhere in the world as long as there is a reliable internet connection.

The use of VoIP has fundamentally changed digital communication. Instead of relying on the traditional PSTN (Public Switched Telephone Network), VoIP allows individuals and businesses to increase their global accessibility while reducing telecommunication costs. At Virtual-Call, we are proud to offer our VoIP services based on the SIP protocol, which is a specialty among VoIP technologies and is specifically designed to establish, manage and terminate calls.

While VoIP is the general term for any type of voice communication over the Internet, SIP (Session Initiation Protocol), which is used exclusively for VoIP calls, is a specification within this broad technology. Together, VoIP and SIP are contributing significantly to the revolutionary change in the communications landscape, which is becoming increasingly digitalized.
