They called my business line at 2:41 AM. The Caller ID shows "Out of Area" and they didn't leave a message. I am unable to call back as a recording says, "Unable to complete number as dialed".
Just received a silent call from this number. I have been receiving numerous silent calls directly to my office number and toll free number. I have blocked CA and AZ on my toll free number and stopped many of those but can't block states/area codes on my office line.
