This calller is calling my parents house earl in the morning. The one time I answered noone said anything.

This number calls at all hours no message nothing.  Called at 7am this morning

Calls several times a day; never says anything when I answer; never leaves a message or voicemail when I don't answer. If I had to guess I'd say a ROBO-Dialer with no purpose.

My father keeps getting a call from this number.  When he answers, there is an automated attendant claiming that his AT&T account due date has changed and offers to take payment immediately by phone.  He does have AT&T accounts, but none are past due, so I strongly suspect this is some sort of scam.

I got a call from this number today claiming that they were ERC (Enhanced Recover Center). It's an Automated attendant voice. I told it that it sounded like a recording and hung up. I'm guessing it's some sort of debt collection number. Even if it is, I'm not talking to a recording.
