UNIVERSAL INTERNET TELEPHONE SYSTEM

摘要

There is described a method for setting up a call over the Internet between a Web-based phone and a phone device. The Web-based phone is loaded on a Java-- enabled computing device. The call involves a Web application hosted on an external server capable of communication with a SIP Server on which the Web-based phone is pre-registered. Upon request from the computing device, the external server sends an HTTP message to a SIP Switch which in turn forwards a SIP NOTIFY message to the computing device through the SIP Server. The Web-based phone then pops up on the computing device and the call initiation can be confirmed. There is also described a platform independent Web-based phone as well as a Web application for auto- -populating a contact directory from contacts on a social networking Web site.
