Received a strange number of calls to the system voice phone, help me analyze the situation?
This number is like a fixed phone, coupled with the landlord said after the connection is a voice, rather than live, probably a hoax. The above is just my personal point of view, only for the landlord reference.
My dad today also received a such a phone (phone number 5381513, and you said exactly the same), said the package has drugs, gave him a call, let him hit this number alarm.
