Deer make a wide variety of vocal sounds. many of them change meaning depending on body language or other communication activity such as a foot stomp or tail twitch.
Calling may be prodctive, counter productive or produce no results at all. Much depends on the caller knowing what vocal sound to make, how to make it, when to make and when, most important of all, to shut up.
I have been calling deer for about 35-years. I have learned a great deal about it. What I do most of the time now, is nothing. Deer, just as it is with turkeys or elk, become call shy. I occasionally use a friction call, doe contact call during the pre-rut and that is about it.
I mostly shoot does having gotten my fill of trophy hunting and have no need to call them. However, last year, just for fun, I started fooling with two small, 2.5-year old bucks. They would respond to a young buck grunt, a doe bleat, a fawn bleat, both doe and buck mews and a doe contact call.
I don't believe you will find that true of a mature buck.
