This is from a very annoying carpet cleaning service that calls a few times a week.

Got a call from these guys at 6:45am.  They hung up without saying anything.

These people phone every day - at least 4 calls per day.  Blocking systems failed to stop calls.  This number finally showed up on id capture and it is a false front.  Report to local police.

Caller is not identified on Caller ID.  The text "Out of Area" appears followed by the phone number 646-792-5400.  When I called the number, an automated message plays that states "we're sorry your call cannot be completed as dialed.  Please check the area code and numbre abd dial again."
