VoIP: Emerging Trends and Technologies describes the issues arising in deploying VoIP in emerging heterogeneous network environment. Along with a brief overview of the concepts, protocols, algorithms, and equipment involved in realizing VoIP, the book focuses mainly on two areas: the quality and performance issues in deploying VoIP over various network settings; and the new mechanisms, protocols in the emerging networks to assist the deployment of VoIP. Together,the book provides a unified view to the advances made both in the VoIP technologies and network technologies that guides the effective deployment of VoIP services.
