You never talk to the people that are processing the the form if all you ask about is the status. The person answering the phone just checks the status on a computer. You are not disturbing the examiner. If you have any other questions they will give you the number to contact the person doing your form.
I didn't check the status on a Form 1 I sent in for six months. When I did call I found out it had been mailed three months earlier. I had to request an official copy. The copies don't have a stamp which is kinda a bummer. So I normally check the status after about what is the normal processing time just to make sure it wasn't lost somewhere.
