In Office Communicator 2007 and Office Communications Server 2007, Microsoft has completely overhauled its Live Communications family of software. With new PBX connectivity, the new suite pulls the public telephone network into the equation, making it possible for people on landlines and cell phones to join VoIP-based conversations and data conferences. "Presence" detection is also a major theme in the new software suite.
