In this industry we use a lot of terms that we think are understood, but they aren’t. Kind of ironic for an industry that has a mission to help people communicate. My point isn’t to argue the definition of UC, but to talk about definitions. You see, all the technology in the world can’t help us communicate and/or collaborate if we can’t get past the basics of language. UC as a broad category works because we all understand it’s a broad topic whose definition varies with the beholder.
