A communication node and corresponding method for processing data communication passing through the node between a first data network and a second data network is described. The method includes detecting an event associated with data communication arriving at the node from the first data network, and determining whether the data communication is to be suspended for service at the node based on the detected event. Suspended data communication is processed based on information in the data communication. Return data communication arriving at the node from the second data network in response to the processed data communication from the first data network is detected. The detected return data communication is allowed to pass through the node without processing the detected return data communication.

Platform and method for providing data services in a communication network

A distributed telephone answering system has intelligence distributed to a plurality of workstations. Each workstation may connect to a plurality of long distance telephone networks. Also, each workstation is controlled by a central controller. A central resopurce such as a database of call context information may be accessed by each workstatin. A workstation may support one or more human users.

Associating call appearance with data associated with call

An agent workstation in a computer-telephony system is controlled to provide a fault tolerance technique. A telephony device driver in the workstation is controlled by a server process in the workstation. A first client process interfaces a controller to the server process. The controller is also interfaced to the server process by a second client process, the second client process serving as an alternate interface between the controller and the server process in the event of failure by the first client process. Control of the server process by the controller is transferred from the first client process to the second client process in the event of failure by the first client process.

Fault tolerant telephony control

A call management technique implemented using a call routing engine is described. The technique of the present invention may be used to advantage to implement dialed number translation techniques in a global system connected to different telephone networks.

Call management implemented using call routing engine

Techniques for associating a call appearance with data associated with the call are provided. In the techniques of the present invention, the association of the call appearance with the data is based upon matching of non-dialed number identification data.

In accordance with the present invention, a telephony control fault tolerance technique is provided. In one embodiment of the technique of the present invention, a computer-telephony agent (CTI) workstation is provided with a primary telephony control communication path between primary telephony control mechanism external to the workstation and a telephony application interface (TAPI) process, for use in controlling a telephony device in the workstation, internal to the workstation. In the event of failure of the primary path, a secondary telephony control communication path may be established between the TAPI process and a secondary telephony control mechanism that may be comprised in the workstation.

A call management technique implemented using a call routing engine is disclosed. The technique of the present invention may be used to advantage to implement dialed number translation techniques.
