Weiss said they could've just as easily made the call from the library but Ruby wanted to see the CCT itself.

Also, I'm pretty certain it's the same exact building and not just a relay/side station, considering it's the same place that Cinder infiltrated, and they also told us that the CCT is on Beacon's campus, along with the fact that it's part of Ozpin's tower.
