One of the major implementation of the VoIP is in the Internet Protocol phones. Their appearance is similar to the normal phones with buttons, handset and a cradle. In addition, the IP phones use the RJ-45 Ethernet cables instead of the standard RJ-11 connectors. The phones are directly connected the router and have the necessary software and hardware to make the IP call. In addition, the existence of Wi-Fi phones permit subscribers to make VoIP calls near Wi-Fi hot spots. Finally, the Computer-to-computer calls is certainly one of the easiest method of using VoIP. This method uses a certain software that is provided at a very low cost by several companies (Wallingford, 2005).
The only needed items are a speaker, sound card microphone and a preferably fast internet connection. Computer-to-computer calls normally have no charges apart from the monthly ISP fee.
