July 20, 2016, 1:29 PM - prerecorded home security call from "410-290-0220 Columbia MD" to my landline which is on the national DNC list. Prerecorded call in a woman's voice that started with saying "Hello, this is . . . the FBI reports a break in every ... minutes. " and "If you will let us place a sign in your yard, we will give at absolutely no cost to you . . " The message eventually gave button options.
Third party blocking service seems to intercept calls from this number.
We got a call from this number with CID name set to "VINTAGE" on August 1, 2016. It rang only once and did not call back. Our third party blocking service (rhymes with SlowNoHobo) intercepts calls after the first ring if the caller ID number is on their blacklist or triggers their "Advanced Robocall Detection" algorithm(s,) so it's likely they're already clamping down on calls from this number.
I check 800notes when the blocking service nixes a call in case there's a mistake. My thanks to folks for their posts above; seems the service did its job well this time. I'm posting about my recent call in case knowing this CID number is already on the service's radar helps anyone else.
