Abstract
A networked telephony system and method allow users to deploy on the Internet computer telephony applications associated with designated telephone numbers. The telephony application is easily created by a user in XML (Extensible Markup Language) with predefined telephony XML tags and easily deployed on a website. The telephony XML tags include those for call control and media manipulation. A call to anyone of these designated telephone numbers may originate from anyone of the networked telephone system such as the PSTN (Public Switched Telephone System), a wireless network, or the Internet. The call is received by an application gateway center (AGC) installed on the Internet. Analogous to a web browser, the AGC provides facility for retrieving the associated XML application from its website and processing the call accordingly. The architecture and design of the system allow for reliability, high quality-of-service, easy scalability and the ability to incorporate additional telephony hardware and software and protocols.

16. A method of processing a telephone call to a call number in a networked computer telephony system, comprising:
-
providing a plurality of Extensible Markup Language (XML) documents hosted by a web server among a plurality of web servers on the Internet, each of said XML documents constituting a telephony application associated with a specified call number and including telephony-specific XML scripts with tags instructing how a telephone call to the specified call number is to be processed;
providing a plurality of application gateway centers, each capable of processing the telephone call by retrieving and processing the XML document associated with the call number of the telephone call;
periodically pinging from each of the plurality of application gateway centers to the plurality of web servers to rank the accessibility of each application gateway center to the XML document associated with the call number; and
directing the telephone call to be processed by the application gateway center with a predetermined rank.
