I randomly stepped through the movie and managed to stumble on an example which seems to be exactly the sort of thing FranceBB described. Maybe the intention was to illustrate how a master Jedi commands midi-chlorians to do his bidding, allowing him to warp spacetime and make space-calls where there's no carrier service.
I guess Luke's showing off and not even using a device to make the call because he wants to get laid, but he is on the phone in the sample video.
