商品描述
The first complete guide to planning, evaluating, and implementing high-value SIP trunking solutions 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(R) experts show how to use Session Initiation Protocol (SIP) trunking to eliminate legacy interconnects and gain the full benefits of end-to-end VoIP. 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. 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. 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. 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. - Discover the advanced Unified Communications solutions that SIP trunking facilitates - Systematically plan and prepare your network for SIP trunking - Generate effective RFPs for SIP trunking - Ask service providers the right questions--and make sense of their answers - Compare SIP deployment models and assess their tradeoffs - Address key network design issues, including security, call admission control, and call flows - Manage SIP/TDM interworking throughout the transition This IP communications book is part of the Cisco Press(R) Networking Technology Series. IP communications titles from Cisco Press help networking professionals understand voice and IP telephony technologies, plan and design converged networks, and implement network solutions for increased productivity.

第一本完整的指南，規劃、評估和實施高價值的SIP中繼解決方案
大多數大型企業已經轉向IP電話，而服務提供商的骨幹網絡也大多轉換為VoIP傳輸。但有一個關鍵的缺失環節：大多數企業仍然通過老式、不靈活的TDM中繼連接到其服務提供商。現在，三位Cisco(R)專家展示了如何使用會話啟動協議（Session Initiation Protocol, SIP）中繼來消除舊有的互連，並獲得端到端VoIP的全部好處。
本書是為企業決策者、網絡架構師、顧問和服務提供商撰寫的，揭開了SIP中繼技術和趨勢的神秘面紗，並為從TDM到SIP互連的過渡帶來前所未有的清晰度。作者將SIP中繼的真正好處與神話區分開來，幫助您系統性地評估和比較服務提供商的產品。您將找到詳細的成本分析，包括識別現實可實現的節省的指導。
SIP中繼還介紹了優化網絡設計和安全性的基本技術，提供了實施的最佳實踐，並通過一個從頭到尾的案例研究展示如何應用這些技術。
Christina Hattingh，Cisco接入路由技術組（Access Routing Technology Group, ARTG）的技術人員，從Cisco VoIP技術的起源開始參與，並持續在這些領域提供諮詢和培訓。Darryl Sladden，Cisco高級產品經理，是Cisco統一邊界元素（Unified Border Element）和Cisco SIP中繼策略的主要架構師，也是AS5000產品及其他幾個Cisco VoIP技術的主要貢獻者。ATM Zakaria Swapan，Cisco ARTG的技術人員，是Cisco SIP開發、Cisco統一邊界元素、VoIP網關、安全統一通信、無線語音、QoS和呼叫接納控制及其他幾個VoIP技術的主要貢獻者。

作者簡介
Christina Hattingh is a member of the technical staff in the Access Routing Technology Group (ARTG) of Cisco. The ARTG router product portfolio, including the Cisco 2800, 3800, 2900, and 3900 Series integrated services routers and their predecessors, was one of the first Cisco platforms to converge voice and data starting in the late 1990s by offering TDM voice interfaces, WAN interfaces, and critical QoS features. Over time sophisticated call control and routing elements were integrated into the router-based platform making stand-alone VoIP deployments and wide inter-vendor VoIP network interoperability possible. In this role, Christina trains Cisco sales staff and customers and consults widely on voice network deployment and design. She is a long-time speaker of the Cisco Networkers and CiscoLive conferences. Christina holds a graduate degree in mathematical statistics and computer science from the University of Pretoria, South Africa. Darryl Sladden is a product manager at Cisco and has been with Cisco for more than ten years. Currently, Darryl is a member of the ARTG at Cisco. The ARTG responsibilities include the Cisco ISR and ISR G2, AS5000, and the Cisco Unified Border Element (CUBE). Darryl has been a key contributor to the AS5000 product, CUBE, and several other VoIP technologies at Cisco for several years. The CUBE and the AS5000 product lines are widely used by service providers and enterprise customers as border elements between SIP, H.323, and TDM networks. Darryl has worked with many service provider and enterprise customers who use CUBE to implement SIP Trunks into both Cisco Unified Communications Manager (CUCM) and Cisco Unified Communications Manager Express (CUCME) solutions. Darryl has a degree in mathematics from the University of Waterloo and holds a patent in the use of voice-based network management, and several other patents are under consideration. ATM Zakaria Swapan is a member of the technical staff in the ARTG at Cisco. The ARTG responsibilities include the Cisco 2800, 3800, 2900, and 3900 Series integrated services routers and the CUBE. ATM has been a key contributor to SIP, Secure Unified Communications, Wireless Voice, Network Intelligence, Network Virtualization, RSVP, and many other developments. ATM has also worked with service providers and enterprise customers who use CUBE to implement SIP Trunks into both CUCM and CUCME solutions. ATM holds an M.S. degree in computer science from Texas A&M University and a B.S. degree in computer science and engineering from Bangladesh University of Engineering and Technology (BUET).
