VoIP is highly praised for its wonderful savings when it comes to long distance phone calls. VoIP is the acronym for Voice Over Internet Protocol. This refers to the transmission of audio, over the Internet, to an awaiting PC user or other VoIP user. Calls may even be routed from a computer to a standard landline phone.

VoIP is changing the way the world looks at telephone services. Because VoIP is neither PSTN (the public switched telephone network) nor Circuit Switching Networks, it is a new technology complete to itself. VoIP is referred to as Packet Switching, because the audio is transferred as a packet then sent over the Internet.

When VoIP began to surface on the Internet there were many programs that you could download to your computer, absolutely free, and then place long distance calls. Some of the more familiar programs include Dialpad and Skype.
