This app is great. It keeps me signed in and available on the iphone and iPad even when I'm not in front of my computer or logged in on the computer, and the notifications are pleasant and discreet. I use a Mac and Communicator for Mac is terribly unreliable in the way our company has configured Exchange Server and Office Communicator Server for remote employees. This app is well worth it. Don't hesitate.
