In some cases they do extend the medical, so you might not get to do it. However there are cases where they might ask you to redo it since it expired. I think you should be good if they already said you passed the medical, if they havent looked at it yet, then you may get a request to do it over. It all depends on them!!!I don't think you can call them from India. I called them earlier from within Canada for my hubby and could not get through to an agent. ours is asking for more documents..his medical had expired last month but no request for a new one!..we submited on June 2016 outland..our 1st anniversary was yesterday since it was received..God help us.
