This spoofed invalid number calls almost every day, despite being blocked. It is an invalid number because number prefixes cannot end with "11", like 911, 711, etc, so it is almost certainly a scammer making these calls.
This number repeatedly calls our house. We have learned to leave our home phone unanswered. It is ridiculous the amount of telemarketers considering we are supposedly on the "do not call list!"
Fools keep calling, never leaving a message. Oh wait! They don't get that far since my call blocking service hangs up on em! 10:07 am today. Caller ID said "CALIFORNIA"
