I noticed a call from this number.

I can only tell you that it is a fax number for a company that describes itself as a "Leading publicly traded commercial real estate firm".  It is listed as the fax number for sending resumes to on CareerBuilder.com.  It doesn't list the name of the company only that it is located somewhere in Charlotte. I was looking up the number to see if I could find out where exactly it was in Charlotte and I found your post.  Hope this helps.
