摘要： A system and method of operating a communication system is described. A communication interface receives a first user request for a voice service from a communication device. In response to receiving the first user request, the communication interface transfers an initial message requesting access to the voice service. The communication interface receives a response to the initial message that indicates that the voice service is not available. After receiving the response, the communication interface receives a second user request from the communication device. A processing system processes the second user request to determine if the second user request indicates an emergency service. If the second user request indicates the emergency service, then the communication interface transfers a call request for the emergency service. If the second user request does not indicate the emergency service, then the communication interface notifies the communication device that the voice service is not available.

摘要： A system, a method and computer-readable media for monitoring the state of a call. A system is provided that includes a user device configured to send and receive voice packets over a bearer path and further configured to send and receive signaling messages over a signaling path. The system also includes a media gateway configured to communicate the voice packets to the user device over the bearer path. In addition, the media gateway is configured to monitor the bearer path and to generate status messages indicating whether the bearer path is still active. The system further includes a call agent configured to maintain a record of the call by attempting to communicate with the user device over the signaling path and by utilizing the status messages received from the media gateway.

摘要： Embodiments of the present invention provide methods, systems, and computer-readable media for achieving a higher call completion rate in a system experiencing a mass calling event. The present invention has several practical applications in the technical arts including optimizing use of network resources during a mass calling event. In various embodiments, a network's resources are efficiently utilized by way of sampling a network element's control processing unit utilization. Additionally, the various embodiments respond by selecting to negatively acknowledging callers in a mass calling event state in order to prevent system components from becoming overloaded. Overloaded network system components lead to such issues as dropped signaling packets, and higher percentages of call failures. Embodiments of the invention are directed to achieving optimal call completion in the case of a mass calling event.

摘要： 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.

摘要： In a packet communication system, session border controllers receive and process communication packets to detect DTMF signaling. If DTMF signaling is detected, the session border controllers determine if DTMF transcoding is required. If DTMF transcoding is required, the session border controllers transfer DTMF transcoding instructions to a DTMF transcoding server. In response to the transcoding instructions, the DTMF transcoding server transfers transcoded DTMF signaling.

摘要： A call control system comprises a communication interface and a processing system. The communication interface is configured to receive a first access request from a communication system requesting access to a voice service. The communication interface is configured to, in response to receiving the first access request, transfer a rejection to the communication system that indicates that the voice service is not available. The communication interface is configured to, in response to transferring the rejection, receive a first call request for a priority service from the communication system. The processing system is configured to process the first call request to determine if the first call request indicates the priority service. If the first call request indicates the priority service, then the communication interface is configured to transfer a second access request to a communication network in response to the first call request. The communication interface is configured to, in response to transferring the second access request to the communication network, receive a first successful response from the communication network. The communication interface is configured to, in response to receiving the first successful response, transfer a second call request to the communication network.

摘要： A packet device is disclosed for recovering timing information from packets that were transmitted over a packet network. The packet device is comprised of a buffer and a synchronization system that includes a clock. The buffer receives packets that were transmitted based on a transmitter timing signal, and fills to a target number of packets. The buffer receives a receiver timing signal from the clock, and transfers the packets based on the receiver timing signal. The synchronization system determines a measured number of the packets in the buffer at any given time. The synchronization system compares the measured number to the target number to recover timing information. The synchronization system then adjusts the second timing signal based on the timing information.
