I don't see any point in calling, what do you want to see on the flop?. If you hit an ace you still have to be concerned about AK,AQ,AJ and it's unlikely that your going to flop a nut flush or straight. Your more likely to flop a draw and be faced with another difficult decision post flop. So either push or fold. You are short stacked but AT is a dog against AK,AQ,AJ,AA,KK,QQ,JJ,TT. If your opponent holds any pair smaller than ten's its a coinflip. Even if he hold KQ suited your not a huge favorite. If you push and get called you do so knowing that you are at best in a coin flip but more than likely well behind.
