I've received 2 calls on my cell phone from this number over the past 2 days. Since the caller doesn't bother to leave a message, I am assuming it is from someone unknown to me. I also have my cell phone number on a "do not call" list, which doesn't seem to be working.
Caller had called before and left no message. This time I picked up to find out. Caller said good morning at 4 pm and then just music. I hung up after shortly thereafter.
