What is VoIP?
VoIP stands for Voice over Internet Protocol. As the term says VoIP is the transmission of voice communication through IP packets and, therefore, through the Internet. VoIP can use accelerating hardware to achieve this purpose and can also be used in a PC environment. Webopedia defines it as: A category of hardware and software that enables people to use the Internet as the transmission medium for telephone calls. For users who have free, or fixed-price Internet access, Internet telephony software essentially provides free telephone calls anywhere in the world. To date, however, Internet telephony does not offer the same quality of telephone service as direct telephone connections. There are many Internet telephony applications available. Some, like CoolTalk and NetMeeting, come bundled with popular Web browsers. Others are stand-alone products. Internet telephony products are sometimes called IP telephony, Voice over the Internet (VOI) or Voice over IP (VOIP) products.
VoIP (Voice over Internet Protocol) allows you to make telephone calls using a computer network, over the Internet and is an industry standard alternative to traditional landline telephone connections. VoIP converts the voice signal from your telephone into a digital signal that travels over the Internet, then converts it back at the other end so you can speak to anyone with a regular phone number.
Voice over Internet Protocol is the ability to make and acquire phone calls over your internet connection instead of using a traditional phone line. VoIP transforms your voice into small data packets (think email) over your high-speed Internet connection; you’ll hear a dial tone and dial just as you always have.
