robo-spam from Washington state about new windows

Called twice this morning ... I am in LA.  I thought this looked like a legitimate number because of no 0's at the end.  But I see it isn't.

...patio doors and entry doors all at Low-E energy efficiency... press 1 to blah blah blah... press 2 to remove your name from...

YEAH RIGHT. PRESS 2 TO ACKNOWLEDGE THAT YOU'RE A REAL PERSON SO THEY CAN SELL YOUR NUMBER TO ANOTHER TELEMARKETER.

A new illegal/scam/contractor cold-call from the state of Washington.
Washing State was the reason we purchased our first D***t**e call blocker over two years ago.
We have EVERY area code in the state of Washington blocked on our office and home lines.
We now have three D***t**e call blockers.  
Two blockers for our office lines and one for our home line.
Our phones do not ring when a blocked call comes in and our home and office are not disturbed by their calls.
When you block an entire area code, you potentially block 6,000,000 to 8,000,000 phone numbers.  Sweet!

Called this morning. I answered/hung up immediately (without speaking), hoping their robo-dialer will decide the number is dead. Hey, it's worth a shot!
