I have moved my main campus from an SX-200 to a 3300 and the security department notified me that they no longer have the 911 alert that they had with the SX200. Previously if any deskset dialed 911, it triggered an alert on their phone and they could see on the display which room and extension placed the 911 call. I did a search for 911 detection and reporting in the 4.0 technician handbook, but with no results. Is the feature called something else now? I really need to get this working
