This is an In-Coming Call only from The Remand Centre (Jail) in Winnipeg, Manitoba it must mean an inmate from this centre is trying to contact you.  You cannot call the number back but you can call the centre's general line at 204-945-3540 to either reach the person who is contacting you or block the floor of that number from contacting you.  In order to block the call you must prove with a phone statement the 204-942-9511 is calling your phone once the number has been blocked from contacting you your number will never be able to be contacted again.  Hope this helped !
