We've just announced the availability of an important new book for our client, VON Publishing, "SIP beyond VoIP," written by three distinguished authors: Henry Sinnreich, Alan B. Johnston and Robert J. Sparks. The foreword by Vint Cerf, the co-inventor of the TCP/IP protocol on which the Internet is based, attests to the world class quality of the book.
"SIP beyond VoIP" Defines the Shift To Internet Communications’ Global Open Standards
“We are in a period where many vendors, service providers, and end users are facing the transition from closed and proprietary VoIP or instant messaging (IM) systems, to SIP based systems,” observed Richard Grigonis, Editor in Chief of VON Magazine. “The authors collectively succeed in educating the reader about a global open Internet standard, the Session Initiation Protocol (SIP) that provides not only VoIP, but also instant messaging, presence, video, mobility, integration with applications and many other features. This raises the question: Why have separate voice and IM communications, separate conferencing, collaboration and mobility services, separate applications and communications?”
