How VoIP Works - WBF Video

Learn how Voice Over IP (VoIP) works in the short technical overview from our Whiteboard Friday video series.

How Does Voice Over IP Work?

Let's talk about Voice Over IP (VoIP) and how Voice Over IP works. This is just a basic introduction. Imagine you have a couple different phones. There's a phone on our left and a phone on the right. Voice Over IP takes an analog signal and it converts it into a digital signal and sends it over an IP network.

Different pieces of the conversation are sampled and turned it into a set of ones and zeroes. The ones and zeros are the computer language translation of the human conversation. Those ones and zeroes are the content that is transmitted over the IP network.

That translation goes over the wide area network or the local area network coded into the IP format (the internet protocol). Then, on the other side, the opposite happens. The ones and zeros are decoded and we turned back into the content that you would hear on the handset.

In review: an analog signal is coded into an IP format, then the IP format is decoded on the other side using a Codec. A Codec is what is used in Voice Over IP to code and then un-code the audio signal.

What You Need to Make VoIP Work for You

In order to make this system function properly you need a system that's able to interpret the Codec signals and turn them into a call. That's where Voice Over IP is utilized in services like VoiceMaxx or VoiceMaxx CE, which is the West Unified Communications Services solution for hosted PBX, applications in the cloud.
