Abstract

A direct telephone dialing scheme for initiating internet telephone service from a web page is provided. The scheme allows a caller, using an internet telephone service, to place telephone call to a telephone number appearing on any web page directly from that web page. In one embodiment, a caller navigates to a desired web page on the internet and the caller dials a telephone number on that web page directly to initiate a two-way audio communication with the destination telephone number using an internet telephone service. The direct telephone dialing scheme of the present invention improves the accessibility and ease of use of internet telephone services. Furthermore, the direct telephone dialing scheme can be used with video, data, and fax a communications which are supported by the VoIP data communication standard.
