§ 717-a. Direct dialing to public service answering points. 1. For purposes of this section, "public building" shall mean any building belonging to the state, county, town, village, school district or any other political or civil subdivision of state or local government.

2. For purposes of this section, "multi-line telephone system" shall mean any system comprised of common control units, telephone sets, control hardware and software, and adjunct systems which enables users to make and receive telephone calls using shared resources such as telephone network trunks or data link bandwidth. This term includes, but is not limited to, network-based and premises-based systems such as Centrex service, premises-based, hosted and cloud-based VoIP, as well as PBX, Hybrid and Key Telephone Systems, as classified by the FCC under Part 68 of its rules.

3. All public buildings which operate on a multi-line telephone system in this state must configure their multi-line telephone system hardware to allow any call to 911 on the system to be directly connected to a public service answering point; provided however, that in the case of public buildings governed by section three hundred fifty-five or six thousand two hundred four of the education law which have on-campus emergency answering points, such public buildings may route such 911 calls to their on-campus answering points.

4. The requirements of subdivision three of this section shall not apply to any public building operating on a multi-line telephone system that would be required to upgrade the hardware of their telephone network to meet said requirement. However, every telephone in any exempt public building operating on a multi-line telephone system shall place an instructional sticker on or immediately adjacent to each telephone informing users of the phone's inability to directly dial 911 and the procedures to follow to connect to a 911 public service answering point, or in the case of public buildings governed by section three hundred fifty-five or six thousand two hundred four of the education law which have on-campus emergency answering points, such on-campus answering points, in case of an emergency.
