Abstract: An IP origination point and method to determine transcoding in packet communications are provided. The IP origination point in one example embodiment includes a communication interface configured to exchange packet communications with a media transport path, a storage system configured to store an origination communication, payload data for the origination communication, integrity information for the origination communication that is configured to be modified by one or more transcoding operations, and returned integrity information that may have been modified by the one or more transcoding operations. A processing system generates and transmits the origination communication into the media transport path, compares the returned integrity information to the integrity information, and determines a transcoding level of transcoding that occurred in the media transport path if the returned integrity information is not equal to the sent integrity information.

Abstract: A Dual Tone Multi Frequency (DTMF) circuit for relaying DTMF digits includes a communication interface, a storage system configured to store a sampling window size, a DTMF test sequence, a returned DTMF sequence, and one or more DTMF digits, with the one or more DTMF digits to be transferred to a second DTMF circuit by the DTMF circuit, and a processing system. The processing system receives the one or more DTMF digits via the communication interface and an input sampling window, generates the DTMF test sequence and transmits the DTMF test sequence to the second DTMF circuit, compares the DTMF test sequence to a returned DTMF sequence received back from the second DTMF circuit, and if the returned DTMF sequence is not the same as the DTMF test sequence, adjusts the sampling window size of the input sampling window.

Abstract: An originating device coupled to an originating network requests a media call to a terminating device coupled to a terminating network. In between the originating and terminating networks, a tandem network receives a signaling message for the media call transferred by the originating network. The tandem network retrieves and processes numbers for the originating device and the terminating device from the signaling message to determine a loss adjustment for the media call and to select the originating device or the terminating device to make the loss adjustment. The tandem network transfers a loss instruction indicating the loss adjustment to the originating network or the terminating network for delivery to the selected device. The selected device receives the loss instruction and responsively makes the loss adjustment.

Abstract: A method for operating a control module to allocate traffic exchanges between an intermediate network and a plurality of carrier networks in a communication system is provided. The method includes monitoring first traffic transferring from the intermediate network to a first carrier network to determine an amount of outbound traffic, and monitoring second traffic transferring from the first carrier network to the intermediate network to determine an amount of inbound traffic. The method also includes determining a supplemental amount based on the amount of outbound traffic and the amount of inbound traffic, and transmitting a control message that identifies the supplemental amount to a second carrier network instructing the second carrier network to transfer supplemental traffic in an amount less than or equal to the supplemental amount.
