When calling 911 during an emergency, always be prepared to provide your location in as much detail as possible. While the technology has improved, calling 911 from a cell phone still does not provide the same location information as calling from a traditional landline phone. Even current technology can have a range of a few meters to a few hundred meters when providing location information for your 911 call from a cell phone. This technology also does not provide altitude information, so while the specific building you are in may be determined, whether you are on the 1st or 5th floor may not.
When calling 9-1-1 from a VoIP or landline phone in most UW owned buildings (off-campus buildings may go to Dane County), the call will be answered by the dispatchers at the UW-Madison Police Department. If you call 911 from your cell phone, the call will be answered by the Dane County 911 Center.
