Yhe its the same for me. I dont know who is this unknown caller. I still replied them once like dont call back.

But still i get the call during some critical situations.I got a call when i was in a interview.

Just answered a call from this number(home phone number, not on any Do Not Call lists).
Said "hello hello" a couple of times and then the other party hung up.
Looked at this site and did not bother to call them back.

Being on Do Not Call doesn't protect you from charities.   They are allowed to call you.
I have had several calls from this number but do not answer it.  They do not leave a message.

We have had calls from this number at the same time on the last three days,they do not leave a message on our answer service. We are registered but these people still call how is that
