Please give your timeline then its easy to understand.
If your medical reports are received and you have paid RPRF and even you have submitted PCC then within year you will get reply from them.
But if you have something pending then they will ask you to complete the formalities require by them.
So just wait or drop an email and ask about your status if they have not updated your status.
They generally don't update due to so much of loads.
About phone call ...........yes they will call you if it is necessary.
Even I have got call from them just to inform our status because since last year they have not updated my status, no communication was there from their side.
Hope this info will help you.
