They call & let ring & then don't leave a Voice Mail.

Looks like they have a whole bank of phone numbers they call from...

360-322-6685
360-322-6708
360-322-6737

No such thing as a reverse call trace, so go ahead make the death threats to them.  I also record them without their consent!!! When they call the police, and if they do, you get their information, and you can let the police know that they are breaking the law by trespassing on your telephone.  

My worthless police department won't bother to take a report unless I am a business.  I recorded such fact with the Microsoft Scammers.  Terrorists are welcome in Austin, Texas says Austin Police Department.

Isn't it interesting that all of these calls come from Blue States?

Port your number to Callcentric, and selectively call forward all calls from that area code to your Senator's office!!! Look at the campaign finance reports and see if you get his or her's home phone number, and forward it there.

Diane Fienstein and Nancy Pelosi get some of the calls made from Cardholder Telephone Terrorists.
Turbin Durbin needs some of the calls too!

I set the account up with call centric to block 1-360* (blocking all 360 area code numbers!)  I don't know or want to know anybody from Nazington (formally Washington)

Especially Austin Police Department.  They are worthless.
