Resilient application layer overlay framework for converged communication over Internet protocol networks

摘要

Methods and apparatus for providing converged communication services in a communication system are disclosed. A first endpoint of the system communicates with at least a second endpoint of the system via session initiation protocol (SIP). At least a portion of the SIP communication is controlled utilizing an application layer overlay framework which permits substantially simultaneous operation of the first endpoint in two application layer protocols, the two application layer protocols including SIP and web services protocol. The web services protocol may illustratively comprise an application layer web services transport protocol such as SOAP/HTTP. The application overlay framework comprises a web services interface, with the web services interface being configured to permit access to information associated with the SIP communication by one or more communication service applications of the system.
