A Word about Product Names

From time to time solutions providers change the names of their products or bundle several products as a new offering. A new name does not imply that the original product is no longer available or is no longer supported by the manufacturer/developer. Since this book went to print Avaya has announced a number of name changes reflecting the evolution of their technologies, but will continue to use both old and new names for the convenience of long-time customers. If you have any questions about products mentioned in this book, please contact your Avaya sales representative.
