Internet Communications Using SIP: Delivering VOIP and Multimedia Services with Session Initiation Protocol (Networking Council Series) - Tapa dura

"...a good book for what it is..." (M2 Communications, 22 April 2002)

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.
