Synopsis
VON Publishing’s latest effort is SIP Beyond VoIP, an extraordinary 333-page effort that picks up where previous books have left off about SIP (Session Initiation Protocol), the protocol that has revolutionized the world of VoIP. The book’s three distinguished authors relate in great detail how this versatile and extensible protocol has truly “moved beyond VoIP” and is now starting to have an impact on the whole telecommunication industry, including wireless and enterprise communications. Anyone who thinks that SIP has any real competitors will come away from this book in astonishment. “SIP Events” are the glue that even now integrates communications and applications. And “SIP Presence” may well be the “dial tone” of the 21st century. The book’s advanced discussion of SIP interleaves with such associated topics as DNS (the Domain Name Service), ENUM (electronic numbering), NAT (Network Address Translation) and firewall traversal, security, Peer-to-Peer SIP (P2P SIP) networks, SIP-based conferencing/collaboration and even accessibility to communications for disabled people. This heavily illustrated, footnoted and fully-indexed book also has a foreword by Vinton Cerf, who writes: “It is my honest opinion that we have barely scratched the surface of the various applications to which SIP may be adapted. If we have seen 1% of the applications of SIP so far, then there are still 99% waiting to be invented, developed or deployed. The generality of SIP will make it a major workhorse the Internet of this century.” If you think you “know” SIP, think again. Get this book–its authors will “set you straight” about SIP, once and for all!
