When someone is sued, they have to be personally served, which means touching the servee with the papers by the servor, or by restricted certified mail, return receipt.  (only the Defendant can sign).  If the Defendant is ignoring service, then the attorney or Plaintiff can go to court, file an affidavit and based on that affidavit, get an order allowing the papers to be served by posting them on the door.  That would be good service, and if no answer is filed, he gets a default Judgment and can collect.

With that as a background, perhaps the lawyer did the latter.  No matter what, you have no obligation to do anything if you don't want to.  As a lawyer, I would appreciate a voice mail or call indicating that no one by the Defendant's name lives at your address.  Of course if he is sleezy, he won't care and will file a proof of service with the court saying the Defendant was served and then get a default Judgment. So, I guess what I am saying is, it is up to you.  Although if you don't call and they do get a Judgment and want to levy on that Judgment and think the Defendant lives at your address, you could get a sheriff showing up at some point to take your stuff to satisfy the Judgment because they think the Defendant lives there.  Why chance it, my advice is to make the call, and sent a letter to the attorney with a copy to the court for the file. It's a hassle and sucks, but protect yourself.
