ENHANCED H.323 GATEWAY WITH IVR AGENT AND H.323 GATEKEEPER

by Kanchei Loa, Mike Sugino and Dave Whittington

l INTRODUCTION

  l The present invention relates generally to method and apparatus for enhanced H.323 Gateway with IVR Agent and H.323 Gatekeeper for Voice over IP (VoIP) applications.

BACKGROUND

  l Motorola IPO has had H.323 gateway imple- mentation in the VoIP products called VIPR. However, because of the limitation of hardware and software resources within the VIPR, there is no flex- ible call routing, address translation, billing and IVR functions in the system. The VIPR only provides static call routing table, static address translation table, primitive Call Detail Record (CDR), and no IVR at all.

  The H.323 Gatekeeper is an H.323 entity on the network that provides address translation and con- trol access to the network for other H.323 entities. The Gatekeeper also provides other services such as bandwidth management and locating gateways. The call routing and bill functions can be centralized at the gatekeeper to provide flexibility and scalability to the telephony system based on H.323.

  By implementing the H.323 gatekeeper and IVR agent, the VIPR could accommodate the following features:

Settlement functions among service providers.

   Secure Web interface to the user account administration and other house keeping functions.

  l Link with VeriSign and CyberCash for Certificate and electronic fund transfer on the Internet.

Other features provided by the backend sys-

tems

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

  The preferred embodiment of the present inven- tion describes the technical requirements for the enhanced H.323 gateway interacts with the IVR agent and H.323 Gatekeeper. The underlined IP net- work supports a communication network for all components. The present invention augments ITU
H.323 protocols accommodate flexible voice func- tions through the IP network.
