  • Patent number: 8160234
    Abstract: A technique is disclosed that optimizes the background noise experienced by a party who is calling into a call center. Working as part of an overall call-assignment algorithm, the technique considers the acoustic noise that is present in the vicinities of multiple call-center agents who are otherwise satisfactory candidates to handle a call. The technique then selects an agent to handle the call who is associated with an optimal acoustic noise. Typically, the selected agent is associated with lowest background noise level. The background noise is monitored at each call agent's station by evaluating the signals that are present at the agent's microphone. Usually, this is done when a call agent is between calls and, as a result, is not using her headset at that moment. In other words, the background noise is actually measured, and the measurements are then used to assign a call agent to the incoming call.

  • Patent number: 8000464
    Abstract: When a call offer is received by a telecommunications peering network destined for a telephone number maintained within a peering database, the telecommunications peering network attempts to route the call directly to the peering partner telecommunications (e.g., broadband, voice over internet protocol, etc.) equipment. If the route fails with a corresponding destination unreachable failure code, the telecommunications peering network can attempt to determine whether or not the telephone number has been ported to a different provider. If the telecommunications peering network determines that the telephone number has been ported, the telecommunications peering network removes the telephone number from the peering database.

  • Patent number: 7995737
    Abstract: Independent telephony systems are integrated by using symmetric forking from both systems. Calls received by either system are forked to the other system. Thus, a call can be accepted by one of the systems, using its external interfaces, and presented to all devices in both systems. Each system is enabled to leverage internal call control advanced features to enhance overall user experience. Internally inserted parameters to call requests are used between the two systems for preventing endless loop of calls between the integrated systems.

  • Patent number: RE43361
    Abstract: The present invention is a telecommunications system having separate switch fabric and switch intelligence. The system comprises a switch fabric, a switch intelligence, and a feature processor. The switch intelligence is logically separated from the switch fabric and comprises a switch fabric proxy, a facility service, a connection manager service, and a call segment instance service. The switch fabric proxy is coupled to the switch fabric via a vendor-specific first Application Programming Interface (API). The switch fabric proxy supports a second API, which is common across all vendors, representing functions supported by the switch fabric. A facility instance, which is instantiated by a facility service using a facility model, represents the bearer and signaling facilities of a party to a call, and interacts with the switch fabric proxy via the second API to communicate with the switch fabric.
