How VoIP Works?

With VoIP, analog voice calls are converted into packets of data. The packets travel like any other type of data, such as e-mail, over the public Internet and/or any private Internet Protocol (IP) network.

Using a VoIP service, you can call landline or cell phones. You can also call computer-to-computer, with both parties speaking into a computer microphone and listening through computer speakers or headsets.

When evaluating, it's worth noting that you can make or receive calls using landline telephones. All you need is an analog telephone adapter connected to your network. Also, to ensure the best voice quality and security, consider using your VoIP or other communications system on a private IP network.
