Voice over Internet Protocol (VOIP) refers to the transmission of speech across data-style networks. This form of transmission is conceptually superior to conventional circuit switched communication in many ways. However, a plethora of security issues are associated with still-evolving VOIP technology. This publication introduces VOIP, its security challenges, and potential countermeasures for VOIP vulnerabilities.
