§  52.34   Obligations regarding local number porting to and from
interconnected VoIP or Internet-based TRS providers.

   (a) An interconnected VoIP or VRS or IP Relay provider must facilitate
   an end-user customer's or a Registered Internet-based TRS User's valid
   number portability request, as it is defined in this subpart, either to
   or from a telecommunications carrier or an interconnected VoIP or VRS
   or IP Relay provider. “Facilitate” is defined as the interconnected
   VoIP or VRS or IP Relay provider's affirmative legal obligation to take
   all steps necessary to initiate or allow a port-in or port-out itself
   or through the telecommunications carriers, if any, that it relies on
   to obtain numbering resources, subject to a valid port request, without
   unreasonable delay or unreasonable procedures that have the effect of
   delaying or denying porting of the NANP-based telephone number.

   (b) An interconnected VoIP or VRS or IP Relay provider may not enter
   into any agreement that would prohibit an end-user customer or a
   Registered Internet-based TRS User from porting between interconnected
   VoIP or VRS or IP Relay providers, or to or from a telecommunications
   carrier.

   (c) Telecommunications carriers must facilitate an end-user customer's
   valid number portability request either to or from an interconnected
   VoIP or VRS or IP Relay provider. “Facilitate” is defined as the
   telecommunication carrier's affirmative legal obligation to take all
   steps necessary to initiate or allow a port-in or port-out itself,
   subject to a valid port request, without unreasonable delay or
   unreasonable procedures that have the effect of delaying or denying
   porting of the NANP-based telephone number.
