Who called from 2020445497

I got a call, purportedly from this number, which is not even an assignable number. The message left was two seconds of dead air.

Yes, this is not a valid number. I suspect it might be related to the "fake IRS" calls I've had this week, so I didn't answer and they didn't leave a message.

Rec'd and no answer

I've received at least three calls in the past couple of days. I do not pick up, and they do not leave a message.

044 is an invalid exchange number.  Called at 8PM and was automatically blocked.  Called 20 seconds later and blocked again.
