Understanding VOIP
VOIP (Voice Over Internet Protocol) is a communication technology that allows users to make voice and video calls using the internet instead of traditional telephone networks. It converts voice signals into digital data packets and transmits them over the internet, making communication faster and more cost-effective.
Examples: Applications like Skype, WhatsApp, Zoom, and Google Meet use VOIP technology.
