SCAM.... SCAM!!!!   215-110-0000 keeps calling my landline, however, never leaves a message.  CallerID - "Pennsylvania" and I don't answer calls from unknown numbers.  Per White Pages:  "We did not find a match.  The subscriber number for the given number is invalid" which indicates that this is a SCAM!  Number now Blocked and Reported.

Infuriating! The number calls once or twice every day. When we answer, they've already disconnected. We can't call back because it's an invalid number. What is the scam?!
