Another thing that helps is if you can make your call come from where the deer can't see. Having a ridge behind you or other terrain features that force the deer to come looking for the action.
That is probably the most critical part of calling. Doesn't matter if you're calling a buck or a turkey, they won't come in if they can see where the sound is coming from but can't see the source.
Imagine sitting in your living room hearing someone talking to you from across the room but nobody's there. It would weird you out. But if you heard that same talking coming from another room then you'd go investigate. Same thing with deer.
