You won't get any interesting information out of that phone call, guaranteed. They won't say "oh, that's Bob, we call him the slow-cooker, cause he is the slowest at opening his envelopes."
What kind of information would you think you get out of this anyways?
There is only one appropriate thing to do after submitting your application: Wait at least 2-3 months. If by then nothing has happened, you might want to consider some action.
Don't start comparing yourself with others who submitted some days before or after you. That's like waiting in line at the supermarket and always checking if one of the other lines is going faster. Except in this case it is worse since you can't change the line even if you wanted to.
