What you need to make a VoIP cal

To make a VoIP call, the consumer user requires VoIP software and a broadband connection to the Internet. The software will handle the call routing to make sure the call reaches the intended destination as well as providing the codec. The software can be installed on a variety of hardware devices including traditional telephone handsets (using an adaptor that plugs into the telephone) or a PC or wireless device such as a Personal Digital Assistant (PDA). This use of software-enhanced end-user devices is one of the key distinguishing features of VoIP. Whereas the traditional telephone system contains its 'intelligence' within the network, VoIP makes use of the Internet model of intelligence at the edge of the network. This is often known as the end-to-end principle.

In order to make a call, an account with a VoIP service provider is also required. Different types of VoIP service are available, including services from traditional telephone carriers such as BT, and from specialized VoIP providers such as US firm Vonage and Luxembourg-based Skype. Some VoIP providers provide support only for PC-to-PC calls, while others provide the ability to make and receive calls from IP-enabled devices to users on the PSTN and on mobile networks.

To use VoIP, all you need is:

· High speed internet service (like cable or DSL)

· A credit card account w/ a US or Puerto Rico shipping address (no PO boxes)

· A touch-tone phone

Your connection needs a minimum upstream and downstream capacity of 90kb/s. If you're not sure if you have this, you can contact your service provider to find out.

Of course, these are just the minimum requirements. Many customers benefit from having an expandable cordless phone system. This will allow you to place a phone is any room you desire without running wires, etc.
