Impossible to use, crashes with no reason, almost constantly when coming back to the app, desktop chats dont appear in the current chats, avoid if you can. Unfortunately my company made the choice of Cisco for our internal telephony and IM tool, you might have to live with it. I dont think I ever used an application that frustrating on the phone, with the waste of time that goes with typing long messages again.
