Got the same thing tonight. Used to get it a few months ago, but it suddenly stopped. Started again. Got it twice today. It's a very eerie robotic voice.
they seem to call every day. The first day it happened, I answered and got that creepy recording. I tried calling the number from my cell phone (all the while blocking my number) all you get is a recording that this is a non-working number. I called the police & they told me to keep track of it, and if it continues to come up & file a report. Apparently others are receiving the same call. very creepy!!!!!!!
