Today, technology has improved and VoIP does not just computer to computer calls. Today, if you have a computer and a broadband connection , you can place your computer for phone calls , which means that you can call a person who owns a regular phone from your computer. VoIP specialists consider other options as well and working on a new technology that now allows people to make computer to cell calls. This means that you can call someone on their cell phone from your computer.
