A client-server network for managing internet protocol voice data packets includes a client terminal, for receiving internet protocol voice data packets; a graphical display, for conveying information to a client terminal user; a client terminal controller, for controlling the client terminal; a terminal proxy server, responsive to the internet protocol voice data packets, for sending synchronized signals to the client terminal and the client terminal controller to notify a client terminal user of the voice data packets, the client terminal controller, in response to the synchronized signal, adapted to retrieve information about the incoming caller and convey the information to the client terminal user on the graphical display; and a graphical user interface, displayed on the graphical display, for receiving instructions from the client terminal user, the client terminal controller, in response to instructions received from the user through the graphical user interface, adapted to perform at least one data manipulation task on the voice data packets.

Client-server network for managing internet protocol voice packets

The present invention enhances synchronization when frames are transmitted over an intermediate network by incorporating a synchronization code along with a data frame in a transport frame used to transport the data frame over an intermediate network. The synchronization code is generated and used to check framing and correct framing errors when the data frames are extracted from the transport frames.

A method and system for integrating a computer and a telephone. A stimulus messaging device, such as an analog telephone, is provisioned as a functional messaging device, such as an ISDN telephone, at a switch. The switch communicates with the telephone through a loop interface device. The loop interface device translates ISDN messages destined for the telephone received from the switch into analog signals for the telephone. The loop interface device also sends the ISDN messages received from the switch to a computer associated with the telephone. The loop interface device translates analog signals received from the telephone into ISDN messages for transmission to either the switch and/or the computer. The present invention enhances call control information for an analog telephone and allows tight integration between a telephone and a computer.

The present invention provides a method and apparatus used in an AO/DI networking service that automatically changes thresholds that increase or decrease bandwidth to cause a corresponding change in the rate of data transfer capacity. The AO/DI networking service uses apparatus that comprises a circuit switched network having an end office with a network management center that monitors the circuit switched network. A computer and a packet switched network are connected to the circuit switched network. An ISP connected to the packet switched network and the end office is used for determining the status of telephone circuits in the circuit switched network serving both the computer and the ISP. Once this status is determined, the AO/DI automatically changes thresholds for increasing and decreasing bandwidth thereby effecting a corresponding change in the rate of data transfer capacity for an AO/DI subscriber.

Method and apparatus for transferring a call leg in a telecommunication network and releasing it to free up resources, while allowing retrieval at a later time under specified conditions. Message extensions are provided for interfaces used between service nodes and host switches in a telecommunication networks. The invention is appropriate for use in an integrated services digital network (ISDN), in an internet protocol (IP) telephony network, or in any other type of telecommunication network. The service node sends a transfer request and retrieval conditions -to the switch. The switch stores the conditions and transfers the channel with the appropriate call leg, but can retrieve the call leg when one of the conditions is met.

Channel transfer with retrieve

A call servicing system permits service agents to service customer calls over a data network. The call servicing system includes customer switches that direct calls to and from the customers, agent terminals for use by the service agents in servicing the customer calls, a network switch, a call translation unit, and an Automatic Call Distribution (ACD) server. The network switch receives the customer calls and transfers the calls to the call translation unit under direction of the ACD server. The call translation unit routes the calls to selected service agents. The ACD server selects the service agents to service the calls, and controls the call translation unit to forward the calls to the agent terminals associated with the selected service agents over the data network.
