VoIPVoice over IP, pronounced as four letters. A category of hardware and software that enables people to use the Internet as the transmission medium for telephone calls. For users who have fixed-price Internet access, Internet telephony can provide low-cost, or even free, phone service.
VoIP does not have the same quality as a typical phone line, and for Internet users the low upload speeds and high latency make telephony a less-than-wonderful experience. A variety of hardware and software products that buffer and enhance the voice signal are available, but none have shown to be better than mediocre at this time.
