You may be wondering what VoIP is and how exactly it works. You may have heard the words Voip broadband phone before. Well essentially it's some sort of software or hardware that lets you make calls over the internet. Because the calls are spending most of their time floating around as a digital signal handled by your VoIP for businesses, the cost to manage those calls is almost negligible. As a result you save a lot of money on phone calls.
Many people have used a computer and a microphone to record a human voice or other sounds. The process involves sampling the sound that is heard by the computer at a very high rate (at least 8,000 times per second or more) and storing those "samples" in memory or in a file on the computer. Each sample of sound is just a very tiny bit of the person's voice or other sound recorded by the computer. The computer has the wherewithal to take all of those samples and play them, so that the listener can hear what was recorded.
Voice over internet protocol services is based on the same idea, but the difference is that the audio samples are not stored locally. Instead, they are sent over the IP network to another computer and played there.
