SIP Trunking (Hardcover)

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^® 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.

這是第一本完整指南，介紹如何規劃、評估和實施高價值的SIP中繼線解決方案。

大多數大型企業已經轉換到IP電話，服務提供商的骨幹網絡也大多轉換為VoIP傳輸。但是，還有一個關鍵的缺失環節：大多數企業仍然通過老式、僵化的TDM中繼線連接到服務提供商。現在，三位思科專家將展示如何使用會話初始協議（SIP）中繼線來消除遺留的互連，並獲得端到端VoIP的全部好處。

本書針對企業決策者、網絡架構師、顧問和服務提供商撰寫，對SIP中繼線技術和趨勢進行了解說，並為從TDM到SIP互連的過渡帶來了前所未有的清晰度。作者們將SIP中繼線的真正好處與迷思區分開來，並幫助您系統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，包括如何確定實際可實現的節省。

《SIP中繼線》還介紹了優化網絡設計和安全性的基本技術，介紹了實施的成熟最佳實踐，並通過一個從頭到尾的案例研究展示如何應用這些技術。
