Document Type and Number:
Japanese Patent JP2004506346
Kind Code:
A
Abstract:
A method for providing a pre-paid telephone calling card services to a calling party initiating a voice-based connection to a called party telephone using an internet-based IP Phone process running on a personal computer. The method comprises initiating an A-leg connection between the IP Phone process and an internet gateway utilizing a computer network connecting the personal computer and the internet Gateway, establishing a telephone connection between the internet gateway and a SCP. Once this connection is established, the SCP transmits a request to the calling party through the IP Phone process to provide account and call information. The calling party responds with the requested account and call information using the IP Phone process. The internet gateway then transmits the information to the SCP using DTMF tones. The SCP responds by transmitting an account query from the SCP to verify account and balance information for the calling party. If the account data is successfully verified, a B-leg connection is established between the SCP and the called party telephone and the A-leg and B-leg connections are connected in order to establish the voice-based connection between the calling party and the called party telephone.
