United States E911 Requirements by State for PBX and MLTS

Posted on: September 28, 2017

V1 VoIP stays on top of 911 regulations changes and continually notifies our United States clients of them as we become aware of them.

Many states are adopting legislation to regulate 9-1-1 service as it applies to Multi Line Telephone Systems (MLTS) or PBXs (Private Branch Exchanges). Some states now require enterprises and/or residential MLTS operators to ensure that when a user calls 9-1-1 on their system, ANI (Automatic Number Identification) and ALI (Automatic Location Identification) are provided to the PSAP (Public Safety Answering Point).

For our V1 VoIP United States clients, the following are general summaries of applicable state legislation and/or regulations, as well as links to the legislation or regulations themselves. These summaries should not be taken as official records of state law, but are instead for informational use only.
