Definitions

  • the invention generally relates to voice services over computer and/or data networks.

  • the present invention allows an Internet voice call or other data voice call to be terminated at a local exchange carrier (LEC) or local access provider (LAP) so that a live voice connection can be established between a PC and a plain regular telephone. Due to lack of an accepted term, this service is hereinafter called Terminating Internet Voice Call Service, or TIVC. While this specification prominently mentions “Internet”, the architecture according to the invention is equally applicable to any data network. It should also be noted that in the field of telephony, "terminating a call” involves several consequential steps which are performed at a terminating LEC or LAP, such as generating a ring signal, generating a busy signal, responding to a receiver going off-hook, etc., so that a proper telephone connection is established between two parties.
  • LEC local exchange carrier
  • LAP local access provider
  • the TIVC service would be a significant growth enabler for voice traffic on Internet or other data networks in that it eliminates the three major growth inhibiting problems stated above.
  • the TIVC service also offers a new terminating access service opportunity to LEC's (local exchange carriers) and LAPs (local access providers), consequently increasing network traffic and service revenues.

  • This terminating service will generate new revenue for the LEC /LAP service providers.
  • the TIVC service will allow LEC /LAP to minimize lost revenue from pure Internet PC to PC voice calling, and expand the terminating reach for Internet voice callers to existing plain telephone subscribers around the world.
