Why did he hang up? Was it a fence, ditch, creek, brush line he had to cross or a bunch of hens? If it was the geography of the land then you could circle around and get in front of him. It is a lot easier to call a turkey in the direction he wants to go than somewhere else. Knowing the lay of the land and turkey movement can put the odds in your favor. Even if they are henned up. Sometimes if you call to aggressively the boss hen will go the other direction and this in turn takes the gobbler with her. Giving the impression that he hung up. Try him a little later in the day as the hens may go the the nest. Call a little lower in volumn. Call to the hen in a non chalantly mode just so she'll come to see what's going on. Each situation is different, but without knowing why he hung up, it is hard to suggest a specific thing to try.
Now the being on property where you can't hunt is a tough nut to crack, as far as getting around on a bird. I've had similar problems hunting in Kansas where strick attention had to be paid to property borders. The key to getting birds there was persistence. We could hunt all day and it proved to be the later hours that the toms were receptive to our calls. But the trick still is to know why he hung up. Tomorrow use a different call. That somtimes does the trick also.
Good luck in solving the puzzle.
