(c) Notwithstanding any other law, a business service user that owns or controls a telephone system or an equivalent system that uses Internet Protocol enabled service and provides outbound dialing capacity or access shall configure the telephone system or equivalent system to allow a person initiating a 9-1-1 call on the system to directly access 9-1-1 service by dialing the digits 9-1-1 without an additional code, digit, prefix, postfix, or trunk-access code.
(d) A business service user that provides residential or business facilities, owns or controls a telephone system or an equivalent system that uses Internet Protocol enabled service, and provides outbound dialing capacity or access shall configure the telephone system or equivalent system to provide a notification to a central location on the site of the residential or business facility when a person within the residential or business facility dials 9-1-1 if the system is able to be configured to provide the notification without an improvement to the system’s hardware. This subsection does not require a business service user to have a person available at the central location to receive a notification.

(C) if the telephone system or equivalent system does not comply with Subsection (c), that the business service user agrees to place an instructional sticker immediately adjacent to each telephone that is accessed using the noncompliant system indicating that during the waiver period the telephone is unable to directly dial 9-1-1 and providing instructions for accessing 9-1-1 in case of an emergency. The instructional sticker must be printed in at least 16-point boldface type in a contrasting color using a font that is easily readable.
