Abstract:
1. A method to facilitate web service access to telephony functionality, comprising: allowing a user to enter a request for a telephony action through a web browser over the Internet, wherein the web browser is capable of viewing a web site and allowing access to the functionality provided by a web server; receiving the user request at a web server to access the telephony functionality on a public switched telephone network (PSTN) through a Voice Over Internet Protocol (VOIP) network, and wherein the VOIP network comprises a session initiation protocol (SIP) network which comprises a plurality of SIP servlets that are members of a SIP servlet container, sending the user request to a web service, wherein the web service provides a service not directly available to the web server; in response to the request, selecting an interface between the web service and the VOIP network, wherein selecting the interface comprises identifying and selecting a SIP servlet for processing the request; allowing the SIP servlet to initiate the telephony action specified in the user request on the VOIP network; allowing the telephony action to cause a communication between the VOIP network and the PSTN, and a communication between the PSTN and a telephone; routing the telephony functionality to the PSTN through the interface; and accessing the telephony functionality on the PSTN over the VOIP network.
