This number called my DNC listed landline today at 1403 hours. One glance at the number was all it took for me to know it was a scam artist. I let it ring while I came here to check on which particular scam it was and the call abruptly disconnected. I don't think it even got three full rings. I guess their system gives up fast.
In my opinion DNC DOESN'T work. This came in on my cell phone. If number isn't in contact list, I never answer. These calls are increasing exponentially.
