Starscream answers the phone…
Even if Shockwave won’t.
…. So on the way to Arizona a while ago, we stopped in an (unexpectedly really nice!) Rt. 66 motel…and there was…this phone. It didn’t work, of course, and was in the room just as some vintage decoration.
Also, the handset on this thing was really heavy, and could easily have been used to knock someone unconscious. (People must have been generally stronger to make phone calls back in the day.) This took quite a bit of careful balancing so as not to squash little Screams.
