Multi Line Telephone Systems (MLTS):
Earlier this year an amended version of the MLTS law was signed into law. The new law, PA 30 of 2019, extends the compliance requirement to December 31, 2020 and makes some additional exemptions for certain entities. The purpose of these MLTS requirements is that when someone dials 911 from a MLTS phone and is unable to give their exact location, dispatch needs to be better able to provide responding agencies with the most accurate location possible. Ie. Building address, floor number, room number, area of building, etc. We have had instances in the past where a robbery was occurring at a local branch of a bank, 911 was called, but responders were sent to an area 20 minutes away because 911 received the location of the bank headquarters where the phone line was registered, not the actual location of the phone that was calling 911.
