VoIP stands for Voice over Internet Protocol.
Aliases: IP telephony & voice over IP.
VoIP is replacing outdated copper telephone lines in homes and businesses because it is simple and cheaper. The system transfers your voice and data through an Internet connection instead.
Sound confusing? VoIP is much simpler than it sounds.
VoIP users can make calls similar to using a digital telephone. The user interface often looks just like a smartphone’s contact list.
Where VoIP stands out is behind the scenes: all of the digital information required to signal, establish a channel, digitize an analog voice, and encode a call is sent as “IP packets” (more on that later) over a packet-switched network.
VoIP is far more efficient than a circuit-switched network – which reserves a route and associated bandwidth – hence the lower costs!
VoIP is available over phones, personal computers, tablets – any device connected to the Internet can use VoIP. The beauty of VoIP is that a single service provider can deliver any kind of communication – whether voice, video, or text.
