Book Description
From leading WorldCom engineers--expert guidance on how to plan for SIP implementation
Session Initiation Protocol (SIP) has gained tremendous market acceptance since it became an official IETF Internet communications standard in 1999. SIP is the technology that makes it possible for multimedia communications sessions on the Web--ones that allow voice, video, chat, interactive games, and others to run all at the same time. Now that the deployment of real SIP networks is about to take off, two leaders of the commercial rollout deliver complete guidance on this exciting new technology. Geared to IT and networking professionals and decision-makers at Internet service providers (ISPs), as well as networking (NSPs) and application (ASPs) service providers, this book helps readers sort through the available vendor offerings and services to discover how to integrate and maximize SIP's power across their networks.

From the Back Cover
A complete guide to designing and implementing SIP-based IP communication services The Session Initiation Protocol (SIP) is about to revolutionize telecommunications. This exciting protocol can be used to establish voice, video, and data sessions on the Internet, making a separate network for voice no longer necessary. The integration of voice with all other Internet services provides the greatest opportunity for innovation. Written by the authors who contributed to the development of the protocol and carrier class services based on SIP, this book explores what SIP does and the new services it enables. You’ll find a critical assessment and detailed look at how IP communications based on SIP will enrich communication on the Internet. Sinnreich and Johnston also provide you with a better understanding of how SIP can be used with several key features of legacy telephony networks such as SS7 and ISDN signaling and for H.323 networks. Softswitch solutions are also discussed. They clearly explain the multiple design and implementation issues as well as the decisions you’ll have to make in order to provide SIP-based IP communication services. Reflecting the latest developments by the IETF, this book covers: SIP-enabled communications, multimedia, and conferencing Elements of an SIP network, including user agents, servers, and location services Basics of SIP Security such as authentication, encryption, digital signatures, and firewalls Future services for SIP
