VoIP, or Voice over Internet Protocol, is a technology that allows people to make voice calls using the Internet instead of traditional telephone lines. It converts sound into digital data and transmits it over the Internet, making it possible to communicate through services like Skype, WhatsApp, or Zoom. VoIP offers a more cost-effective way to make local and international calls, as it typically requires only an Internet connection rather than a phone network. It can be used on computers, smartphones, or specialized devices.
