Years and years of telemarketing calls from the same guy, leaving the same message.  It's whack-a-mole with him.
http://www.nbcconnecticut.com/troubleshooters ... -260436221.html  has some background on him.

We got a call from this number today at 1:42 pm and didn't answer. The caller ID was CHICOPEE MA. No voicemail message was left. It will be added to our call blocker. We got a call with the same caller ID from 413–610-2060, which is already blocked.

Criminal Telemarketing Scammer who denies that the Do Not Call Registry exists and will call you racist and bigoted names if you ask him to stop calling...all while identifying himself as a Bible-thumping Christian.

Calls and leaves a lengthy msg . Scammer
