Who called from 4049206777

They call and when you answer no one says anything

this number calls frequently and when I answer it is silent

I called them back and the response was a recording asking me to enter my code for a conference call

Looked up the number. At least three search engines show Our Church, Science Church in Georgia.  Calls 2-3 times a day on my phone ID.  Tried calling, but up with some tele con and asks for a conference #.  Can't reach anyone to tell them to put us on do not call list.

calls and then hangs up after saying hello

I got a call from this number 404-920-6777, it is some Church in Victoria B.C., with Phone in Church Service.  It is a scam.  They give you a conference call number and code to call in on their website.  I did a google search and that is what I came up with.
