Called our land line today which is on state and federal DNC.  As one might expect, the scammers didn't bother to leave a voicemail message.  Caller ID showed "Silverdale WA".

Same here.

Caller ID showed "Silverdale WA". No message. Blocked #

They again called our land line today.  No message - naturally.  Low-life scammers won't leave a message since they are illegal calls anyway.  It has been our experience that any phone call that displays a city and state on caller ID is illegal and/or a scam anyway.
