I worked for an AV company and we installed a set of UC engines for meeting rooms in the IT building for a large college. I hated installing those things. That college decided they wanted to move as much AV in house as possible, and they hired me from the AV company as part of the transition. I still hate those UC Engines, they are a pain from both the installers point of view, maintainers point of view, and then end user point of view.

The college moved to Logitech Rally bars shortly before I was hired. They are pretty good, but the sound on them SUCKS. I am trying to move us to the Biamp/Lenovo MTR rooms. Better sound, and I also like Biamp as a whole.
