A Model for Emergency Service of Voip Through Certification and Labeling‪.‬

I. INTRODUCTION Voice over Internet Protocol ("VoIP") promises to upend a century-old model of voice telephony by creating a more dynamic marketplace and by changing the point of control from the central office switch to the end user's device. The transformation to VoIP is only in its very early stages, and it will ultimately impact all sectors of the telecommunications services industry, including traditional incumbent local exchange carders, cable providers, wireless service providers, and emergency service providers. In fact, all of the relevant stakeholders affected by VoIP (e.g., service providers, hardware and software vendors, customers, and governmental agencies) share a great need to analyze the issues raised by the transition from the traditional Public Switched Telephone Network ("PSTN") to a packet-switched, Internet Protocol-based ("IP") architecture. For example, service providers and hardware and software developers are struggling to understand and take advantage of opportunities in this area involving new technology prospects (e.g., integrated messaging and mobile collaboration). Moreover, business, governmental, and residential consumer users of telecommunications equipment and services are seeking guidance on when and how to upgrade to a new technological frontier. Finally, governmental agencies are struggling to ensure that social policy concerns will be addressed in this very different technological environment.
