On a traditional land line your voice travels as an analog signal along telephone cabling from you to your caller. Basically, it’s a sound wave. With VoIP, a special adapter is used to convert your analog voice to a digital signal which can then be transmitted through the internet as digital data – just like any other information that travels the net. When it gets to the other end – the digital data is converted back to analog and your voice comes out the earpiece, just as it went in. There’s no time lapse, no weird beeps and clicks – it’s just like you called on a regular phone.
