The Microsoft Office Communications Server 2007 (OCS) software runs on large server systems and allows people using Microsoft's Office software to manage voice calling from their personal computers and in combination with email, instant messaging and other communications.
The software can allow a user with a headset to make a phone call from a PC, by clicking on a name in a contact list. But it includes far more advanced features, such as being able to add people to a conference call by using a mouse to drag and drop their names across the computer screen.
In addition to the core server software, Microsoft is introducing a companion desktop product, Office Communicator, and a new version of its Live Meeting videoconferencing software. It is also making available its RoundTable videoconferencing device with a 360-degree camera and recording abilities.
Microsoft predicted within five years most offices will rely on the software.
