Yes this number is from 911 operator.
Last night I accidentally called 911 last night and this number called me so I anwsered it it said "You called 911 recently " and I said it was an accident so they asked me couple questions then I was free to go. Remember don't hang up like I did when you accidentally call 911 don't hang up if you dothey will call you back and if you missed it they will send police, ambulance and firetrucks to your house.
So don't play with 911 calls

This number was left on our answering machine. Due to privacy reasons, cannot return call.

it took me a while before i figured out that by pushing any number over multiple times it goes to 911  my kids are very sneaky  on doing this

Just got two calls from this number on my cell this afternoon.  It went to voice mail and a female voice said it was 911 calling - that my cell had called them and to stay on the line if I needed help.  According to my call log its total BS.  This is either a collector going to previously unheard of nastiness or a real a***ole scammer.

yes this is the cps

Same as above.  I was suspicious and tried to call back when my phone log didn't show any 911 call going out.  Automated message says that number doesn't exist.  Tired turning off my phone.  Phone is locked on, ie they continue to listen to your phone even after they have hung up.   It felt a bit creepy so I pulled the battery.   Phone was fine after.   You could turn it on and off.  If you can't it means they've locked you phone line open so they can verify if there really is an emergency.  My daughter was  putting her children to bed at the time and that's always a sob time.  Perhaps they heard that in the background and decided to keep the line open in case.
