  • Patent number: 10602241
    Abstract: The present invention discloses numerous implementations for IP-based call processing systems that can selectively control an outgoing call initiated by a source device to a destination device. The call processing system causes a Service Switching Point (SSP) associated with the source device to initiate a media connection between the IP-based call processing system and the source device. The call processing system further causes initiation of a call feature for the outgoing call using the media connection with the source device. The call feature may include a call restriction feature, a call feature for conveying an audio element to the source device, a call record feature and a call feature for conveying information to the source device. The call processing system further causes establishment of a media connection between the source and the destination devices.

  • Patent number: 8531992
    Abstract: The present invention discloses numerous implementations for IP-based call processing systems that can selectively control an outgoing call initiated by a source device to a destination device. The call processing system communicates with a Service Switching Point (SSP) associated with the source device and determines whether a media message is to be conveyed to the source device. It could determine a media message is to be conveyed to the source device for many reasons including to convey a message related to a call feature, to prompt a user to provide authorization data, to alert a user of particular information or to provide an audio element to the source device prior to establishing the outgoing call. Upon determining to effect control of the outgoing call, the call processing system causes the SSP to initiate a media connection between the source device and the call processing system. The call processing system can then utilize the media connection to convey a media message to the source device.

  • Publication number: 20110164738
    Abstract: The present invention discloses numerous implementations for conveying an audio element to a source device initiating an outgoing call while a user of the source device is waiting for a user of a destination device to answer the call. A call processing system receives a call request message from the source device, determines an audio element from a plurality of audio elements to convey to the source device and initiates conveyance of the audio element to the source device in response to receiving the call request message. The system then causes establishment of a media connection between the source and destination devices and terminates conveyance of the audio element to the source device prior to or substantially simultaneous with the establishment of the media connection between the source and destination devices. In various implementations, the source device may be implemented within the PSTN and/or an IP network.

The call processing system communicates with a Service Switching Point (SSP) associated with the source device and determines whether to effect control of the outgoing call. It could determine to effect control of the outgoing call for many reasons including to convey a media message to the source device, to implement a call feature or to manage call restrictions. Upon determining to effect control of the outgoing call, the call processing system causes the SSP to initiate a media connection between the source device and the call processing system. The call processing system can then utilize the media connection with the source device to perform functionality for the outgoing call prior to and/or during the outgoing call.
