Hello I downloaded 3CXPhone for VoIP Providers ver 2.0.5 from "play store". It seems the "out of office" works intermittently. For some reason it only works once. To make it work again, I have to go back un-check and check and save "out of office" in my profile. But it only works for one time every time. I am running Android 4.1.2. Also, it would be nice, if the phone is in "out of office" state, it should have an "icon" indicating "out of office" state.
