The best way to handle calls from this number is, unless you live in the same area code, when you see a call coming from this area code or North Carolina, that you don't recognize, just DON'T ANSWER IT and go on with your life.D
I have gotten 7 calls from this number in the past week. No one responds when I answer the phone, and they do not leave a message. The calls come in on my work-issued cell phone, which I do not give out my number for (I only receive phone calls from clients and contacts on it - no outgoing calls).
