Understanding the Session Initiation Protocol

by Alan B. Johnston

If your work involves the development and operation of voice or data networks, this ground-breaking book gives you the thorough understanding of SIP (Session Initiation Protocol) you need. It shows you how this revolutionary protocol for IP Telephony provides a highly-scalable and cost-effective way to offer new telecommunication feature sets, helping you design your ?next generation? network and develop new applications and software stacks. Discussions include SIP as a key component in the Internet multimedia conferencing architecture, request and response messages, devices in a typical network, types of servers, SIP headers, comparisons with existing signaling protocols including H.323, related protocols SDP and RTP, and the future direction of SIP.
