Appl. No.:

08/560051

International Classification:

H04M003/42

US Classification:

370352, 37921001

Abstract:

A telephone call is originated in a reverse direction, i. e. , from a called party to a calling party, using a packet switched network. According to one embodiment of the invention, a calling party located in a first country may wish to place a call to a party in a second country having cheaper telephone rates. To benefit from the cheaper telephone rates of the second country, the calling party sends a data message—via a packet switched network—to a service provider in the second country requesting reverse call origination. The request message may be sent to an electronic mailbox maintained by the service provider and located on a global computer network, such as the Internet. The service provider of the second country, upon receiving the message, dials the destination number of the called party supplied in the request message. After reaching the called party, the service provider of the second country dials the calling party and bridges the call between the two parties. The calls thus originate from and are billed at the lower telephone rates of the second country.

International Classification:

US Classification:

379114010, 379114030, 379088010

Abstract:

An approach is provided for originating a telephone call from a country with low telephone rates to a country with high telephone rates using a non-signaling network, such as a global computer network. This can be accomplished without additional specialized telephone equipment or any modifications to switches and databases in either country. Also, the telephone call can be established without any manipulations of signaling information transmitted by a carrier in the high traffic country. Such an approach provides flexible allocation of charges for originating a telephone call from a country with low telephone rates to a country with high telephone rates.

Abstract:

Method and system for calling card validation hubbing provides a hubbed architecture for communicating validation messages relating to a calling card number to be validated between a telecommunications network which accepts a calling card call and the telecommunications network which issued the card. The hubbing system provides transport links and protocol translation between ANSI SS7, ITU CCS7 and X. 25 for each telecommunications network which is attached. When an attached telecommunications network accepts a calling card call, an authorization request including calling card number is sent to the hubbing system, translated to the protocol used by the card issuing network and transported to the card issuing network for validation. Also communicated are request responses, which indicate success or failure of validation, and call disposition messages, which provide a timely estimate of call duration and charges.
