I think this is a call. I don't know how much there is already in the middle, but he is shortstack and could be just shoving to steal the blinds and antes, and his stack is comfortable to put pressure on stacks like yours because if you call and lose you would lose half of your stack.
If you can think about his range and figure that he is shoving Ax 44 is good to call. Make a quick calculation and find the pot odds
, you'll have the odds to call a lot of the time here. You have to take some risks to win more chips.
It's important to think about his range though. With what hands do you think he goes allin to steal? I think that in this situation his range is pretty wide and 44 is ok to call.
