"With the advent of multimedia, the Internet has been converted into a revolutionary communication system that allows people to see and speak to one another, work together collaboratively, and send messages in real time. Despite the widespread and groundbreaking ramifications of this phenomenon, there is a general lack of understanding about the underlying protocol technologies that make it possible. Internet Multimedia Communications Using SIP addresses this deficiency by covering multimedia from both a conceptual and practical point of view. Using UML sequence diagrams and essential code snippets, focus is first placed on the technical aspects of a number of imperative communication protocols including session initiation protocol (SIP), session description protocol (SDP), real-time transport protocol (RTP), and message session relay protocol (MSRP). The book then proceeds to demonstrate theory with practical examples by helping the reader to construct a functional IP soft-phone while referring to the latest research being conducted in IETF and 3rd Generation Partnership Project (3GPP)."--Jacket.
