The phone is ringing, and I don't recognize the number, All Caller ID says is, "NAME UNAVAILABLE".
Please help me figure out who is calling and what they want
The concept of number spoofing has apparently not made its acquaintance with you.
FCC on Caller ID and Spoofing
Someone called me from this number asking about a certain car. Then asked me if I was at work.I just found out now that this could be someone cloning the number and only wanted to know if I was out of the house! Can someone really mask his real number using another existing number?
