15 U.S. Code § 5711 - Federal Trade Commission regulations
The Commission shall by rule require a common carrier that provides telephone services to a provider of pay-per-call services to make available to the Commission any records and financial information maintained by such carrier relating to the arrangements (other than for the provision of local exchange service) between such carrier and any provider of pay-per-call services.
The rules issued by the Commission under this section shall include provisions to prohibit unfair or deceptive acts or practices that evade such rules or undermine the rights provided to customers under this subchapter, including through the use of alternative billing or other procedures.
The rules prescribed by the Commission under subparagraphs (A) and (G) of paragraph (1) may permit, in the case of publications that are widely distributed, that are printed annually or less frequently, and that have an established policy of not publishing specific prices, advertising that in lieu of the cost disclosures required by such subparagraphs, clearly and conspicuously disclose that use of the telephone number may result in a substantial charge.
A rule issued under this subsection shall be treated as a rule issued under section 57a(a)(1)(B) of this title.
The Commission shall prescribe the rules under subsection (a) within 270 days after October 28, 1992. Such rules shall be prescribed in accordance with section 553 of title 5.
Any violation of any rule prescribed under subsection (a) shall be treated as a violation of a rule respecting unfair or deceptive acts or practices under section 45 of this title. Notwithstanding section 45(a)(2) of this title, communications common carriers shall be subject to the jurisdiction of the Commission for purposes of this subchapter.
