Abstract: A method is disclosed that breaks the “one line, one location” paradigm of teleconferencing in the prior art. The teleconference bridge in the illustrative embodiment is able to utilize more than one audio channel from each location. By having access to more than one audio channel from a teleconference location's sound field, the bridge is able to create a multi-channel effect during a conference call. When more than one microphone is present in the first sound field, they can be used to create a multi-channel effect in a second or other sound field involved in a conference call that has more than one loudspeaker. With the bridge mimicking the multi-channel imaging in one room with the multi-channel imaging in another, the conference call participants can experience audio depth during a conference call and can experience two-dimensional imaging, depending on the microphone or speaker separation that is present.

Abstract: The present invention discloses a method for a network to choose an authentication mode, wherein the key lies in that, according to the received authentication information in the authentication vector request message from S-CSCF as well as according to type of the requesting subscriber, HSS returns authentication information of the Early-IMS-based authentication vector to S-CSCF, or returns authentication information of the Full-IMS-based authentication mode to S-CSCF, or directly returns failure information to S-CSCF. If it is under the former two situations, the subscriber will be authenticated by adopting the corresponding authentication mode, and then S-CSCF will return access-allowed or access-rejected information to the subscriber according to authentication result. If it is in the latter situation, S-CSCF will directly send access-rejected information to the subscriber.

Abstract: A call waiting notifying apparatus including a discriminating circuit to discriminate to see if a call reception has been generated from a digital line to an analog terminal in communication or not; and a transmitting circuit to transmit a predetermined tone to the analog terminal if the generation of the call waiting is determined by the discriminating circuit. The discriminating circuit discriminates the generation of the call waiting on the basis of a command received through a control channel of the digital line.

Abstract: An interface adapter is disclosed for utilization with a conventional toll operator position system having a keyboard, video display and controller which interface adapter interface with the TOPS position and external data bases and audio response units in a manner to permit the TOPS position to additionally perform such functions as directory assistance, order entry and line message delivery. The interface adapter includes first and second switching means to intercept the keyboard and video data paths of the TOPS position to isolate the controller and includes a control processor in communication with the external data bases and audio response units which is programmed to respond upon command from the keyboard to access the external data bases and audio response units as required and to communicate such data or audio response to the appropriate terminus.
