If your work involves the development and operation of voice or data networks, SIP (Session Initiation Protocol) is beginning to change the way you do business. Here's a ground-breaking book that quickly gives you a thorough understanding of this revolutionary protocol for IP Telephony. It shows how SIP provides a highly-scalable and cost-effective way to offer new and exciting 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 (Session Description Protocol) and RTP (Real-time Transport Protocol), and the future direction of SIP. Detailed call flow diagrams illustrate how this technology works with other protocols such as H.323 and ISUP.
