Received a call from this telephone number. No message was left. Anonymous callback reached a Verizon Core recording saying that my call could not be completed as dialed.

Follow up post....This is another one of those IRS scammers. Ignore all calls from this number!

Called our spam line twice once at 8:30 and then again at 9:30 AM. We haven't answered that line since January but they keep trying. They got to talk to our fax machine and now they are blocked.  You'd think they would be working on a new scam since most people know about India's take over of IRS collections in the US. lol.

We too got a such a call.  No message.  Another annoying junk caller.
