摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for implementing real-time transport control protocol to obtain an end-to-end encryption and security status of a communication session. The system collects real-time transport control protocol messages associated with a communication session, wherein the real-time transport control protocol messages are generated by devices in the communication session, and wherein the real-time transport control protocol messages include security information associated with the communication session. Then, based on the real-time transport control protocol messages, the system determines a security status associated with the communication session. The system can also generate an indication of the security status associated with the communication session. Further, the system can generate an indication of the security status of a communication session on a per participant basis.

摘要： Systems, methods, and non-transitory computer-readable storage media for implementing real-time transport control protocol (RTCP) to obtain end-to-end session information. The system receives an RTCP extension that is associated with an RTCP packet in a communication session. The RTCP extension may include an instruction for transmitting RTCP data based on a triggering event. The RTCP extension can be configured to propagate along the communication session. Next, in response to the triggering event, the system can transmit the RTCP data to an address defined by the instruction as a destination address for receiving information associated with the triggering event.

摘要： A method is disclosed for acoustic feedback attenuation at a telecommunications terminal. A speakerphone equipped with a loudspeaker and two microphones is featured. Signals from the two microphones are subjected to a calibration stage and then to a runtime stage. The purpose of the calibration stage is to match the microphones to each other by advantageously using both magnitude and phase equalization across the frequency spectrum of the microphones. During the runtime stage, the microphones monitor the ambient sounds received from sound sources, such as the speakerphone's users and the loudspeaker itself, during a conference call. The speakerphone applies the generated set of filter coefficients to the optimized microphone's signals. By combining the signal from the reference microphone with the filtered signal from the optimized microphone, the speakerphone is able to attenuate the sounds from the loudspeaker that would otherwise be transmitted back to other conference call participants.

摘要： A method and apparatus for providing a differential microphone with a desired frequency response are disclosed. The desired frequency response is provided by operation of a filter, having an adjustable frequency response, coupled to the microphone. The frequency response of the filter is set by operation of a controller, also coupled to the microphone, based on signals received from the microphone. The desired frequency response may be determined based upon the orientation angle and the distance between the microphone and a source of sound. The frequency response of the filter may comprise the substantial inverse of the frequency response of the microphone to provide a flat response. In a preferred embodiment, the gain of the differential microphone is adjusted so that the output level is effectively independent of microphone position relative to the source. In particular embodiments, the controller may determine, based on the distance from the sound source, whether to operate the differential microphone in a nearfield mode of operation or a farfield mode of operation.
