Narrative:
Denver sector X handed us off two aircraft at the same altitude on collision courses at FL350 with no positive separation ensured. Aircraft X checked on at FL350 south east bound. The aircraft that was slightly behind at FL350; aircraft Y; was not on our frequency and he needed to be turned to avoid loss of separation. We reached out to denver sector Y to instruct him to turn aircraft Y to the left (apparently denver X took a point out) and denver Y said he was no longer talking to that aircraft. We broadcasted in the blind for aircraft Y. We had to turn aircraft Y while still in denver center's airspace to ensure separation! Without the turn aircraft Y would have lost separation one minute inside our airspace! This is a daily occurrence that has been going on for 30 plus years but seldom gets reported because of a lack of safety culture.
