Sec.  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.
