Abstract

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.

Claims

1. A system for providing third-party call control in a network-enabled telecommunications environment comprising:

a call-control mechanism connected to the Network for providing service logic and routing intelligence for initiating call connections;

a control application running on the call-control mechanism, the control application providing the service-logic description and connection request command instruction for implementing third-party controlled call connections; and

a call-routing entity operating at a public network level accessible to the call-control mechanism;

characterized in that the call-control mechanism using the control application sends primitive text commands to the call-routing entity, which receives, reads and implements the text commands containing all of the service logic and instructions required to successfully construct call connections at the public network level, and wherein the call-routing entity sends notification of success or failure regarding implementation of received commands back to the control application.

2. The system of claim 1, wherein the telecommunications environment includes a voice over Internet protocol (VoIP) network.

3. The system of claim 1, wherein the call-control mechanism is a computer-telephony-integration (CTI) server.

4. The system of claim 1, wherein the call-routing entity is a PBX telephony switch.

5. The system of claim 1, wherein the call-routing entity is an ACD telephony switch.

6. The system of claim 2, wherein the call-routing entity is a voice over Internet protocol (VoIP) gateway.

7. The system of claim 1, wherein the control application contains a call model, the attributes thereof defined in low-level descriptor language.

8. The system of claim 7, wherein the low-level descriptor language is extensible markup language (XML).

9. The system of claim 7, wherein the application comprises a representation of a switching matrix, the attributes thereof defined in low-level descriptor language.

10. The system of claim 9, wherein the low-level descriptor language is extensible markup language (XML).

11. The system of claim 1, wherein the telecommunications environment is an enterprise communications center connected for communication to a dedicated telephone network and to a data-packet-network.

12. The system of claim 11, wherein the telephone network is a public switched telephone network (PSTN) and the data-packet-network is the Internet network.

31. The method of claim 2, wherein the control application contains a call model, attributes thereof defined in low-level descriptor language.

32. The method of claim 31 wherein the low-level descriptor language is extensible markup language (XML).

33. The method of claim 31 wherein the control application comprises a representation of a switching matrix, the attributes thereof defined in low-level descriptor language.

34. The method of claim 33 wherein the low-level descriptor language is extensible markup language (XML).

13-24. -24. (canceled)

25. In a system having a call-control mechanism connected to a network, a control application running on the call-control mechanism, the control application providing service-logic description and connection request command instruction for implementing third-party controlled call connections, and a call-routing entity operating at a public network level accessible to the call-control mechanism, a method for providing third-party call control, comprising steps of:

(a) sending primitive text commands containing service logic and instructions required to successfully construct call connections at the public network level, to the call-routing entity from the control application;

(b) receiving, reading and implementing the text commands at the call-routing entity; and

(c) sending notification of success or failure regarding implementation of received commands back to the control application by the call-routing entity.

26. The system of claim 25 wherein the network comprises a voice over Internet protocol (VOIP) network.

27. The method of claim 25 comprising a computer-telephony-integration (CTI) server.

28. The method of claim 25 wherein the call-routing entity is a PBX telephony switch.

29. The method of claim 25 wherein the call-routing entity is an ACD telephony switch.

30. The method of claim 26 wherein the call-routing entity is a voice over Internet protocol (VoIP) gateway.

35. The method of claim 25 comprising an enterprise communications center connected for communication to both a dedicated telephone network and to a data-packet-network.

36. The method of claim 35 wherein the telephone network is a public switched telephone network (PSTN) and the data-packet-network is the Internet network.
