Cisco Im and Presence Outlook / exchange integration

This is probably a simple answer but I can't seem to find a definitive answer on how Cisco jabber integrates with exchange / outlook.  Does the client communicate with the outlook client via api for presence or does it communicate with the backend exchange server some how.   For instance,  if I set my presence on jabber to away it will immediately change my presence in outlook and even Sharepoint.   Please explain to me how this integration works.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
