A call from this invalid (and obviously spoofed) number arrived today.  When the call rolled to voice mail, the caller left no message.  This pattern is typical of robocallers who use automated dialers to place calls.  If a live person answers, the dialer transfers the call to a live, lawbreaking telemarketer.  This is why it's best to let your answering machine take calls from unfamiliar numbers.

Phone Lice. Blocked.

Receiving harrassing phone calls from this number, than changes the number. When I block it. Keeps calling me at all hours of day and evening. Sometimes I receive 4 to 5 calls a day.
