Heads up TechNet Online subscribers!!! I was digging out a product ID in the TechNet Online are for some installs I'm doing and low and behold I see a nice new nugget in the download area. Sure enough, Office Communication Server (OCS) 2007 Standard Edition is now available for download.
If you aren't familiar with the product, here's the blurb from the FAQ:
Office Communications Server 2007 builds on the foundation of Presence and Instant Messaging, Federated Communications and Remote Call Control delivered by Live Communications Server 2005 and Microsoft Office Communicator 2005. Key new features include a number of improvements to Instant Messaging and Presence capability such as integration with Microsoft Exchange Server distribution lists as well as the addition of software-powered VoIP, allowing users to make, receive and manage voice (phone) calls using Office Communicator 2007 running on their computer and multi-party on-premise audio/video and Web conferencing. Office Communications Server 2007 also supports the ICE framework of protocols, allowing users to take advantage of these communications capabilities from wherever they are without needing to establish a VPN connection.
