(This measure has not been amended since it was passed by the Senate on February 5, 2018. The summary of that version is repeated here.) Kari's Law Act of 2017 (Sec. 2) This bill amends the Communications Act of 1934 to prohibit businesses from manufacturing or importing for use in the United States, or selling or leasing in the United States, a multi-line telephone system unless it is pre-configured to allow users to directly initiate a call to 9-1-1 (without dialing any additional digit, code, prefix, or post-fix, including any trunk-access code such as the digit "9") from any station equipped with dialing facilities. Businesses are prohibited from installing, managing, or operating multi-line telephone systems without such a direct 9-1-1 call configuration. Businesses installing, managing, or operating such systems for use in the United States must configure the systems to provide a notification to a central location at the facility where the system is installed, or to another person or organization regardless of location, if the system is able to be so configured without an improvement to the hardware or software.
