Who called from 4055367379

Well, it looks like I've been added to this "idiot's" list of callers. Rang twice, then no one on the line when I answered.

First call from this number today.  ID said Oklahoma, hung up when I answered call.  I Called back and their answering machine said "This number temporary disconnected."  Is someone casing my house?  Same name on my ID 2/19/13 at 1:46pm it was -Integritas Estate Services.  Could it be the same company/person?

I would like to know who this is.

This person calls my home and when I answer they hang up and when I call back it sales number be disconnected, this number is 405-536-7379

I keep receiving calls from this number, but when I answer.  No one from the other side of the line says anything.  After afew seconds, the other person hangs up, or I get mad and hang up.

The caller never leaves a message in my voice mailbox in case I miss this call.
