  § 64.2201   Ringing indication requirements.

   (a)  A long-distance voice service provider shall not convey a ringing
   indication to the calling party until the terminating provider has signaled
   that the called party is being alerted to an incoming call, such as by
   ringing.

   (1) If the terminating provider signals that the called party is being
   alerted and provides an audio tone or announcement, originating providers
   must cease any locally generated audible tone or announcement and convey the
   terminating provider's tone or announcement to the calling party.

   (2) The requirements in this paragraph apply to all voice call signaling and
   transmission technologies and to all long-distance voice service providers,
   including local exchange carriers as defined in § 64.4001(e), interexchange
   carriers as defined in § 64.4001(d), providers of commercial mobile radio
   service as defined in § 20.3 of this chapter, providers of interconnected
   voice over Internet Protocol (VoIP) service as defined in 47 U.S.C. 153(25),
   and providers of non-interconnected VoIP service as defined in 47 U.S.C.
   153(36) to the extent such providers offer the capability to place calls to
   or receive calls from the public switched telephone network.

   (b) Intermediate providers must return unaltered to providers in the call
   path any signaling information that indicates that the terminating provider
   is alerting the called party, such as by ringing.

   (1) An intermediate provider may not generate signaling information that
   indicates  the  terminating  provider is alerting the called party. An
   intermediate provider must pass the signaling information indicating that
   the called party is being alerted unaltered to subsequent providers in the
   call path.

   (2) Intermediate providers must also return unaltered any audio tone or
   announcement provided by the terminating provider.

   (3) In this section, the term “intermediate provider” has the same meaning
   as in § 64.1600(f).

   (4) The requirements in this section apply to all voice call signaling and
   transmission technologies.

   (c) The requirements in paragraphs (a) and (b) of this section apply to both
   interstate  and  intrastate  calls, as well as to both originating and
   terminating international calls while they are within the United States.
