Abstract: A global communication internet telephone system is a new software Web Call structure, in which the system user only requires a computer with Windows 98® or above, a duplex sound card, a display interface and internet access, and logging directly into a GTD Web 800 web page thereafter, receiving a automatic number dispensing function and GTD automatic number skipping function. The characteristics of the system lies in that a signature which can be linked to the GTD Web 800 web pages for browsing is added into an e-mail of a user computer. As long as an e-mail receiver clicks on the signature file of the e-mail, he can be linked to the web pages and conduct a VoIP dialog with the e-mail sender. If a computer at a sending side is not powered on the sending side can freely choose whether to forward incoming calls to a designated cellular phone or local phone by automatically appointing a number.
