Office Communications Server 2007

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.
