IP Telephony Interconnection Reference: Challenges

Addressing the growth of IP telephony service offerings within the corporate and residential realm, IP Telephony Interconnection Reference: Challenges, Models, and Engineering examines the technical and regulatory issues related to IP telephony interconnection at the large scale. It describes business and interconnection models, reviews emerging architectures such as IMS and TISPAN, identifies commonly-encountered issues, and supplies solutions to technical issues.

The authors offer a detailed overview of SPEERMINT activity and proposed architecture, the current work undertaken in i3 Forum, and the use of ENUM for interconnection—describing practices in both fixed and mobile networks. Among the first books to present information on interprovider communications and interconnection of IP telephony clouds, the text supplies a clear and up-to-date picture of the VoIP protocol jungle.

• Provides detailed guidance on how to implement VoIP interconnect services
• Presents an overview of deployed architectures in fixed and mobile networks used for interconnection and roaming purposes
• Enumerates regulatory issues with a focus on Europe and the United States
• Proposes interconnection models
• Suggests viable solutions to technical issues

This reference supplies an overview of interconnection practices in PSTN/mobile. It proposes solutions for overcoming service engineering issues and includes a set of recommendations to ease the proliferation of interconnection agreements and schemes. Keeping you up to speed with recent developments in IP telephony, the book facilitates the understanding of the technical and regulatory requirements needed to provide global services to your customers and successfully navigate the upcoming migration to a completely IP-based model.

Maria Isabel Borges received a degree in Electronics and Telecommunications engineering from Aveiro University, Portugal, in 1989 and the MSc from the same University in 1998. From October 1989 to September 1990 she accomplished a post-graduation degree at the same University, and was involved in training students at the laboratory of propagation. From October 1990 to February 1991 she worked at TEKA Portuguesa on a Television Receiver Only system. She joined the PT Inovação, S.A. (PTIN), formerly Centro de Estudos de Telecomunicações, in 1991, working on applied research on optical communications, until 1995. Since then, she has been involved in several national and international R&D programs, namely in the area of development and integration of broadband access networks technologies, ATM, IP networking and Services, and VoIP systems. She is involved in training actions and consulting services. She is author or co-author of several publications on the above-mentioned subjects and a reviewer of IEEE Communications Magazine.

Pedro Neves received his B.S. and M.S. degrees in Electronics and Telecommunications Engineering from the University of Aveiro, Portugal, in 2003 and 2006 respectively. Since 2007 he has also been pursuing a Ph.D. in Computer Engineering and Telecommunications at the same University. After graduation, he became a research fellow of the Telecommunications Institute, where he worked on European funded projects on broadband wireless access networks. In June 2006 he joined PT Inovação, working on heterogeneous wireless environments in the context of European and Eurescom funded projects. In 2010 he began his research activities in the area of cloud computing, with emphasis on the relationship of this paradigm with telecom operators. He participated in more than 10 international collaborative projects, is co-author of five international books, and has published more than 30 articles in journals and conference proceedings.

Ólafur Páll Einarsson received a BSc degree in Electical Engineering from the University of Iceland in Reykjavik in 2005. From there he moved to Copenhagen to continue his education in Telecommunication Engineering at the Technical University of Denmark (DTU) and received an MSc degree in 2007. Following his education he started to work for Icelandic Telecom (Siminn) in R&D where he participated in several national and international research projects. Some of the main areas of specialty are SIM development, mobile security, and integrating a national mobile PKI architecture in Iceland.
