On February 16th, 2018 the law to be formally known as Kari’s Law was passed by Congress. Kari’s Law requires that multi line phone systems (MLTS) need to be configured to allow people to contact 911 without having to dial any additional numbers, code, prefix or post-fix. The overall goal of Kari’s Law is to avoid and remove any roadblocks that would keep people from contacting emergency services in a timely manner when an emergency arises.

Whether you operate or simply use an MLTS, it’s important to ensure your system is compliant. Compliance with Kari’s Law could require software and core system upgrades, but not necessarily hardware replacement or additional phone lines.

Michigan is one of twenty states that currently has E-911 legislation that requires interconnected VoIP service providers to offer E-911 services to their customers. Providers must ensure that all 911 calls, as well as a callback number and location information, are automatically delivered to the local Public Safety Answer Point. In addition to a physical address, location information could include more detailed information, such as a floor, office or conference room. This eliminates the pressure on distressed callers to have to explain their location to a 911 operator.

The deadline to be compliant with these criteria in the State of the Michigan is currently set for December 31st, 2019. If operators are found to be in violation, they may be assessed a fine by the Michigan Public Utilities Commission.
