I did not answer and they did not leave a message. Tipical of the calls from many numbers calling these days. I did call the number back (206-445-6185) and received a recorded message that was like a very old computer like voice message. The message informs you that it is an opt out registry for the "Do Not Call Registry as per the FCC Regulations". It gives you instructions to follow to add hour number (I guess) and let's you know that it takes 72 hours before it actually takes affect. I am not sure if it does work, and because of that, I did not do it. I will just see if they call from that number again. Most of the time they do!
Not sure if this helps anyone else or not...
