The individual audio data flows are processed uniformly in each group in terms of the signals thereof, and said audio data flows processed in this way are superimposed in order to form audio conference data flows to be transmitted to the communication terminals.

Abstract: A method and apparatus include a first server that communicates with a second server to cause a call back request to be communicated to an endpoint so that the endpoint can initiate a call back connection with the first server or a third server. Such a call back connection may occur near real time or in substantially real time so that updates can be supplied to an endpoint running an application supported by the server quickly and efficiently. The endpoint may register with the second server such that the second server is able to utilize notification messages for providing call back request information to the endpoint to advise the endpoint of a call back request.

Abstract: A method of conveying a location information representing a physical location of a communication device to another communication device comprises acquiring by the communication device a first location information and a second location information, the second location information being acquired subsequently to the acquiring of the first location information and detecting by the communication device a deviation of the second location information from the first location information representing a change of the physical location of the communication device.

Abstract: A communication system and method for routing communications can include a communication device that is configured to route a communication connection based on empirical data relating to an attempted communication. For instance, in some embodiments the device of a communication system can be configured to utilize stored and classified empirical data for automatically determining a subject of an attempted communication made by a user via the user's communication terminal and dependencies the user for that attempted communication may have on a callee for use in establishing a connection for the caller based on the determined dependencies and determined subject of the attempted communication. Information regarding the determined subject of the communication attempt can be based on the stored empirical data. The attempted communication can also be rerouted to another user based on the empirical communication data if that attempted communication is not established within a pre-selected time period.

Abstract: The invention relates to a method for connecting at least one man-machine interface for manipulating, particularly remotely manipulating, at least one data source connected to a video conferencing system within the scope of video conferences, wherein signals generated by the man-machine interface are transmitted to the video conferencing system via a transmission channel provided for controlling a video camera. The invention further relates to an arrangement comprising means for carrying out the method.

Abstract: The invention relates to a method and a coupling device (10) for dynamically allocating USB endpoints (31, 32, 33, 34) of a USB interface (30), which can be accessed using at least two applications, comprising: a USB interface (30) that has at least two ports (P0, P2, P4), each of which comprises at least one USB endpoint (31, 32, 33, 34); and a control device (20) for dynamically allocating the USB endpoints (31, 32, 33, 34). The control device is designed so as to preconfigure each USB endpoint (31, 32, 33, 34) which is required for the at least two applications by means of an initialization process, and thus the control device can switch the allocation of the endpoints according to the access using at least one of the applications without the USB endpoints (31, 32, 33, 34) affected by the switch having to be deactivated.

Abstract: A speech communication system and a method of improving communication in such a speech communication system between at least a first user and a second user may be configured so the system (a) transcribes a recorded portion of a speech communication between the at least first and second user to form a transcribed portion, (b) selects and marks at least one of the words of the transcribed portion which is considered to be a keyword of the speech communication, (c) performs a search for each keyword and produces at least one definition for each keyword, (d) calculates a trustworthiness factor for each keyword, each trustworthiness factor indicating a calculated validity of the respective definition(s), and (e) displays the transcribed portion as well as each of the keywords together with the respective definition and the trustworthiness factor thereof to at least one of the first user and the second user.

Abstract: In a telecommunications network, an incoming connection request to a primary (mobile) device may be terminated at a selected secondary device based on location information (WiFi connectivity, GPS location, Bluetooth connection). Similarly, a user may move an existing connection from the primary device to the secondary device, and back, by simple interaction with the primary device. A Mobile Device Application (MDA) resident in the primary device may control the termination and movement of connection requests and connections.

Abstract: With the help of a key management protocol, the transmitted key information is authenticated by at least one certificate signed by the terminals, and at least one fingerprint of the public keys or certificate, which were used for authenticating the key information, is added to the useful part of an SIP message. The identity information present in the header of an SIP message is additionally copied into a region of the header or the useful part, and a signature is produced by way of the fingerprint, the datum information presented in the header of an SIP message, the copied identity information, and optionally the certificate reference information, and is inserted into a further region of the header of the SIP message. The additional signature that is produced and inserted can remain uninfluenced during a transmission across several networks of different network operators.

Abstract: Described is a method for channel management on one or more digital signal processors. The method distinguishes itself by the fact that channel management occurs at any time based on a current load utilization of each digital signal processor, taking into account an actual load requirement of each channel and a maximum total performance capacity of each digital signal processor. The invention also relates to a device for carrying out the method.

Abstract: A method for optimum utilization of a queue for calls is provided in a telecommunication system and is controlled by an application, as well as an appropriate telecommunication system. Each call that is in the queue has a particular queue property and can be assigned to an agent, to a two-way announcement that is played by an announcement memory and that is capable of interaction with a call, or to remain in the queue. The method is distinguished in that a call assigned to a two-way announcement is allocated a parameter that causes the queue property of the call to be retained.

Abstract: A temporal sequence of pictures is generated in a method for encoding of a first video stream. To do so, a synchronization signal is used which is derived from a second video stream independently of the first video stream, or the encoding of a second video stream independent of the first video stream is based on the same principle as for the encoding of the first video stream.
