Book Description
This book provides an introduction to the different types of private telephone systems, how they operate and common call processing features they offer. Private telephone systems are communication equipment and software that are owned, leased or operated by the companies that use these systems. Private telephone systems are converting from company unique (proprietary) circuit switched systems to industry standard packet data voice (IP Telephony) systems. You will learn the basics of IP Telephony voice over Internet protocol (VoIP) and why it is so important to private telephone systems. The fundamental parts of private telephone systems are described including telephone stations, local wiring, switching systems, and numbering plans are described and explained. The high growth market for private telephone systems and the key trends are covered providing you with an understanding of which system types are growing the fastest and how some systems are evolving to better compete in the industry. Covered are the different types of private telephone systems. You will discover how multiline key telephone systems (KTS) operate and why they are converting from mechanical systems to automated electronic controlled networks. You will learn how automatic switching systems are used by private branch exchange (PBX) systems to provide features and services not offered by public telephone companies. Explained are the ways private telephone systems can be operated (hosted) by other companies (Hosted PBX/Centrex) and how these systems can provide services similar to PBX telephone systems. Discover how telephone systems can be combined with company information systems using computer telephony integration (CTI). You will learn how IP PBX (iPBX) systems operate and why IPTX is the fastest growing area in private telephone systems. You will learn some of the ways private telephone systems are adding wireless capabilities and industry standard wireless private branch exchange (WPBX) systems. Important call processing features including distinctive ringing, call hold, call transfer, call pickup, line hunting and other features are described. Advanced private telephone system features are explained including automated attendant systems, automatic call distribution (ACD), Interactive voice response (IVR) and Voice mail (VM). A basic introduction to call centers is also included.

Book Description
"This book is like a good tour guide.It doesn't just describe the major attractions; you share in the history, spirit, language, and culture of the place." --Henning Schulzrinne, Professor, Columbia University Since its birth in 1996, Session Initiation Protocol (SIP) has grown up. As a richer, much more robust technology, SIP today is fully capable of supporting the communication systems that power our twenty-first century work and life. This second edition handbook has been revamped to cover the newest standards, services, and products. You'll find the latest on SIP usage beyond VoIP, including Presence, instant messaging (IM), mobility, and emergency services, as well as peer-to-peer SIP applications, quality-of-service, and security issues--everything you need to build and deploy today's SIP services. This book will help you * Work with SIP in Presence and event-based communications * Handle SIP-based application-level mobility issues * Develop applications to facilitate communications access for users with disabilities * Set up Internet-based emergency services * Explore how peer-to-peer SIP systems may change VoIP * Understand the critical importance of Internet transparency * Identify relevant standards and specifications * Handle potential quality-of-service and security problems

Book Description
A complete and systematic treatment of signal processing for VoIP voice and fax This book presents a consolidated view and basic approach to signal processing for VoIP voice and fax solutions. It provides readers with complete coverage of the topic, from how things work in voice and fax modules, to signal processing aspects, implementation, and testing. Beginning with an overview of VoIP infrastructure, interfaces, and signals, the book systematically covers: Voice compression Packet loss concealment techniques DTMF detection, generation, and rejection Wideband voice modules operation VoIP Voice-Network bit rate calculations VoIP voice testing Fax over IP and modem over IP Country deviations of PSTN mapped to VoIP VoIP on different processors and architectures Generic VAD-CNG for waveform codecs Echo cancellation Caller ID features in VoIP Packetization—RTP, RTCP, and jitter buffer Clock sources for VoIP applications Fax operation on PSTN, modulations, and fax messages Fax over IP payload formats and bit rate calculations Voice packets jitter with large data packets VoIP voice quality Over 100 questions and answers on voice and more than seventy questions and answers on fax are provided at the back of the book to reinforce the topics covered throughout the text. Additionally, several clarification, interpretation, and discussion sections are included in selected chapters to aide in readers' comprehension. VoIP Voice and Fax Signal Processing is an indispensable resource for professional electrical engineers, voice and fax solution developers, product and deployment support teams, quality assurance and test engineers, and computer engineers. It also serves as a valuable textbook for graduate-level students in electrical engineering and computer engineering courses.

Book Description
Translates technical jargon into practical business communications solutions This book takes readers from traditional voice, fax, video, and data services delivered via separate platforms to a single, unified platform delivering all of these services seamlessly via the Internet. With its clear, jargon-free explanations, the author enables all readers to better understand and assess the growing number of voice over Internet protocol (VoIP) and unified communications (UC) products and services that are available for businesses. VoIP and Unified Communications is based on the author's careful review and synthesis of more than 7,000 pages of published standards as well as a broad range of datasheets, websites, white papers, and webinars. It begins with an introduction to IP technology and then covers such topics as: Packet transmission and switching VoIP signaling and call processing How VoIP and UC are defining the future Interconnections with global services Network management for VoIP and UC This book features a complete chapter dedicated to cost analyses and payback calculations, enabling readers to accurately determine the short- and long-term financial impact of migrating to various VoIP and UC products and services. There's also a chapter detailing major IP systems hardware and software. Throughout the book, diagrams illustrate how various VoIP and UC components and systems work. In addition, the author highlights potential problems and threats to UC services, steering readers away from common pitfalls. Concise and to the point, this text enables readers—from novices to experienced engineers and technical managers—to understand how VoIP and UC really work so that everyone can confidently deal with network engineers, data center gurus, and top management.
