my police dispatchers get the call, from that point they send PD over to the call, then they call ems, or fire, also depending on the call they will call in als. when i get the call over my pager in theory they give us the dispatch time. my pcr has a case number from pd, and the time the call was received. we are to fill in the rest of the times(responding, out on the call, to hospital,clear hospital and time als arrives) .my response time starts as soon as i get the page.
