The company said the server would be launched this fall as a separate product and not part of Windows Server 2003. The server, based on\u00a0Session Initiation Protocol\u00a0and SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE) standards, was originally touted as a feature of the new operating system, which ships next week. The company did not announce licensing terms, but did say a subset of the technology, namely its presence awareness capabilities for tracking users online, would be offered as a free add-on to Windows Server 2003. Microsoft also will make available a set of APIs and a SIP proxy so developers can build presence directly into their applications.CRM software maker\u00a0Siebel Systems\u00a0went on the offensive last week in an effort to quash reports that its customer satisfaction reviews were less than stellar. The reports stem from data in a confidential, Siebel-sponsored survey, which the company says was unlawfully leaked. "Someone has taken, selectively, eight pages of the 75-page report, clearly marked 'confidential,' and over the past month systematically leaked it to members of the financial community, press and analyst community," said Nitsa Zuppas, senior director of public relations at Siebel. "It was clearly stolen and leaked. It was a violation of the law, and we have the FBI looking into it."The software maker didn't dispute the authenticity of the leaked data, but says it was taken out of context. "In any given survey what we've seen is a couple of problem areas," said Steve Mankoff, senior vice president of technical services at Siebel. Mankoff stressed that overall, Siebel's customer satisfaction scores were extremely positive.Optical network vendor Ciena last week acquired privately held multiservice edge switch maker WaveSmith Networks for $158 million in stock.
