I recommend if you are calling to corral a friend to hunt with you then you can watch your back down wind side easier. Do not call for more that 30 minutes at the most. Look your area over carefully before you pack up to leave so you don't educate them. Yes if there is one there are more.
Do not over call the area either.

A lot more information can be found here.
