What is VoIP?
VoIP: VoIP (Voice over Internet Protocol) is technology that converts voice into digital data packets and transmits them over the internet — replacing traditional phone lines. Instead of a copper wire circuit, your voice travels as data alongside emails and web traffic.
How It Works
When you speak into a VoIP phone or app, the software samples your voice thousands of times per second, compresses it into data packets using codecs (like G.711 or Opus), and sends them over your internet connection. At the other end, the packets are reassembled and converted back to audio. This happens in milliseconds, creating a real-time conversation indistinguishable from a traditional call.
Business Use Cases
Businesses use VoIP to replace expensive traditional phone systems (PBX) with cloud-based platforms that include call routing, voicemail, conferencing, and analytics — all for a fraction of the cost. Remote teams use VoIP apps on laptops and phones to stay connected without desk phones. Contact centers use VoIP to handle thousands of simultaneous calls with no hardware investment.
