Went from usable to terrible. I get multiple instances of the same one incoming phone call, then the call drops completely. No matter the setting, none of the calls ring. Even if you have the application set to run in the background, and set to use data regardless, the app disconnects completely everytime the window is minimized. You can have the app open, staring at it, and you'll get an automatic missed call when it never even rang. Don't waste your time or your company's money.

There are so very few things you can adjust with this app & I dislike the layout, the fact that my phone can't control the settings, and as of a few days ago I don't even get the whole screen to come up when a call cones in. On the tiny ribbon I get, it takes forever for the data to scroll so I can see who is calling. If I had another option, I'd use it!!!

I've tried this app and the legacy app on several different phones and it just won't connect. It registers and shows my name but can't answer calls, or make calls, only see who's calling. One if my coworkers has the legacy app on his phone and it actually works. The rest of us can't get it to work in any of our devices. It seems like they need to make it a little more universal for more devices.
