Internet Telephony Service Provider

The insider's guide to IP-based telephony: development, network deployment, testing, and beyond Now that virtually every leading telecommunications service provider has committed to delivering IP-based telephony services, communications professionals face the enormous challenge of implementation. This hands-on guide brings together today's best-known answers and solutions for delivering Voice Over IP (VoIP) services with the quality customers demand. No other book covers the combined issues of protocol signaling, media transport methodology, reference topological considerations, and voice quality testing in service offerings. Bill Douskalis presents systematic coverage of every aspect of IP-based telephony: Coverage includes: A realistic reference topology for implementing and benchmarking voice quality in IP telephony Detailed explanations of call setup using each major competing technology Signaling, bearer transport, and other key network elements In-depth network and service performance analysis in both "normal" and impaired scenarios State-of-the-art traces and performance measurements taken from actual IP networks No matter what your role in delivering VoIP services, IP Telephony delivers the specifics you need to speed deployment, improve reliability, ensure quality, and simplify troubleshooting. Precise, thorough, and based firmly in the real world, it is simply indispensable. The accompanying CD-ROM contains Hewlett-Packard Internet Advisor software that runs off-line--view live VoIP traffic examples! It also includes sample capture files of the H.323, MGCP, and SIP protocols; the latest IETF Working Group documents for VoIP; and an assortment of whitepapers and application notes that provide a real-world view of IP telephony.

Never before have communications technologies moved so quickly or changed so dynamically. The use of standard computing hardware and the influence of the Internet have lead to so-called next-generation networks. This book explores the evolution to the new world of 'Next-Generation Networks' and services: The telecommunications industry is facing one of its toughest challenges yet - the transition from circuit-switched to packet-switched voice networks. Companies need to seize the opportunity of the convergence of voice networks and the Internet to deliver exciting and useful services. "Next Generation Network Services" explains technologies that have, and will influence this change, and brings together technologies such as softswitching, IP telephony, network directories and application frameworks. Features: Fixed and wireless telephony. Internet technologies. Standards. Understanding business goals in implementing a next-generation telecommunications network. A forward look at future services via telecommunications networks and their implications. Network-based services and hosted solutions for customers from computer telephony integration (CTI) through to the rise of the Application Service Provider.This book will interest telecommunications professionals as well as engineers who are working on current circuit-switched and future networks.
