This text is an effort to demystify Session Initiation Protocol (SIP) trunking and illustrate how to use it to eliminate older interconnects and get the full benefits of VoIP. Topics include: an overview and trends in IP telephony, transitioning to SIP trunks, cost analysis, SIP trunking models, interworking, deployment scenarios and best practices, case studies, and the future of unified communications. Authors are Hattingh and Swapan (Access Routing Technology Group, Cisco) and Sladden (product manager, Cisco). Annotation 漏2010 Book News, Inc., Portland, OR (booknews.com)
Publisher Summary 2
The first complete guide to planning, evaluating, and implementing high-value SIP trunking solutions聽Most large enterprises have switched to IP telephony, and service provider backbone networks have largely converted to VoIP transport. But there's a key missing link: most businesses still connect to their service providers via old-fashioned, inflexible TDM trunks. Now, three Cisco庐experts show how to use Session Initiation Protocol (SIP) trunking to eliminate legacy interconnects and gain the full benefits of end-to-end VoIP. 聽Written for enterprise decision-makers, network architects, consultants, and service providers, this book demystifies SIP trunking technology and trends and brings unprecedented clarity to the transition from TDM to SIP interconnects.聽 The authors separate the true benefits of SIP trunking from the myths and help you systematically evaluate and compare service provider offerings. You will find detailed cost analyses, including guidance on identifying realistic, achievable savings. 聽SIP Trunking also introduces essential techniques for optimizing network design and security, introduces proven best practices for implementation, and shows how to apply them through a start-to-finish case study.聽Christina Hattingh, member of the technical staff in the Cisco Access Routing Technology Group (ARTG), has been involved with Cisco VoIP technologies from their inception and continues to consult and deliver training in these areas. Darryl Sladden, a Cisco Senior Product Manager, has been a key architect of the Cisco Unified Border Element and the Cisco SIP Trunking strategy as well as a key contributor to the AS5000 product, and several other Cisco VoIP technologies. ATM Zakaria Swapan, Cisco ARTG member of technical staff, has been a key contributor to the Cisco SIP development, Cisco Unified Border Element, VoIP Gateway, Secure Unified Communications, Wireless Voice, QoS & Call Admission Control and several other VoIP technologies.聽鈥⒙?Discover the advanced Unified Communications solutions that SIP trunking facilitates 鈥⒙?Systematically plan and prepare your network for SIP trunking鈥⒙?Generate effective RFPs for SIP trunking 鈥⒙?Ask service providers the right questions-鈥揳nd make sense of their answers鈥⒙?Compare SIP deployment models and assess their tradeoffs鈥⒙?Address key network design issues, including security, call admission control, and call flows鈥⒙?Manage SIP/TDM interworking throughout the transition聽This IP communications book is part of the Cisco Press庐聽Networking Technology Series.
