The first thing you don't do is spook any birds in the process of trying to roost them. Don't use any turkey calls, just locator calls after fly-up. I have had good success with a coyote howler, just make the howl short so you can hear the bird. In my experience they gobble soon after the first sound you make and if your howls are long you won't hear the gobble.
