VoIP, short for Voice over Internet Protocol, is a technology that lets you make phone calls using the internet instead of traditional telephone lines. When you talk on a VoIP call, your voice is turned into digital data and sent over the internet, just like an email or a message. This makes communication faster, cheaper, and more flexible, especially for businesses and people who need to talk to others across cities or countries.
VoIP is used in many services like WhatsApp, Zoom, Skype, and even office phone systems. It allows voice, video, and messaging to be integrated in one system. VoIP works well on computers, smartphones, or special internet phones. It reduces the cost of long-distance calls and adds features like call forwarding, voicemail, video calls, and more—making it a modern and smart way to communicate.
