Almost 5 months have been passed but no Medical call under class 175

Hi,

I have lodged the VISA application along with my ACSunder general migration skills on 1 Mar, 2011. The eVisa status is showing the receipt of fee as well on the particular date. I have lodged all the necessary documents of myself, my wife and my baby excpet my wife's IELTS test result which is still to be gone through. But from that date there is no status update on my profile. I am still waiting for my medical call or any proceede. Can anybody help me out in this regard pls?
