Always call during 1am STOP please

Called at 3 AM in the morning.  No message.

Thankfully, I had the ringer turned off in my bedroom, but they called at 2:45 AM this morning. The call generated a message on my recorder, and it sounded like someone was there, but they didn't say anything and hung up. Possibly a tv or music in the background, I really couldn't tell. Something needs to be done. I welcome a call at this hour if it's an emergency family situation, but not from some randomness.

Called at 4:00 am.  No one responded. Just background noise. We are on the do not call list.

Same experience as above, but got two calls in a row mid-day.  Then the one at 1:45 CDT.  I head the background noise and at first thought it was a pocket dial, but then the robo voice came on.  It almost sounded like we could make a pass through call so the recipient's caller id would show a bogus number.  Calls back to the -1007 number result in a recording that this is not a working number
