Something I've noticed: Abrams has pretty much dismissed intercoms and desktop communications terminals in favor of using the handheld communicators for pretty much all person-to-person communications purposes. Guess it makes sense since eventually the TNG-era shows effused the shipboard intercom system in favor of just using the commbadges for that sort of thing.
And it probably reflects the modern usage of cell phones.
That said, there were instances in TOS where characters used communicators for intraship contact -- starting with the very first appearance of a communicator ever, in Pike's quarters in "The Cage."
