USING XML EXPRESSED PRIMITIVES FOR PLATFORM AND SYSTEM-INDEPENDENT CALL MODELING

A system for providing third-party call control in a telecommunications environment is provided. The system comprises, a call-control mechanism for providing service logic and routing intelligence, a control application for providing service-logic description and command instruction for implementing third-party controlled call connections, a call-switching mechanism for providing an abstract state of switching matrix and for commutation of external and internal call legs and a commutation application for making and breaking call connections according to commands sent from the control application. The call-control mechanism, using the control application, sends primitive text commands to the call-switching mechanism, which utilizing the commutation application, receives, reads and implements the text commands containing all of the service logic and instructions required to successfully construct call connections and wherein the call-switching mechanism by virtue of the commutation application sends notification of success or failure regarding implementation of received commands back to the control application.
