  • Patent number: 6839555
    Abstract: The present invention supports a voice messaging service in a wireless communications system. A subscriber accesses a voice messaging system (VMS) through a wireless device in order to retrieve voice messages that are deposited into the subscriber's voice mailbox. The subscriber may wish to return a call to a call sender. The call is established to the call sender's directory number through a serving mobile switching center (MSC) in concert with a service control point (SCP) and an intelligent peripheral (IP). The subscriber may return to the VMS so that the subscriber can resume the voice mail session. The subscriber ends the call or optionally enters a feature rebound code. The IP detects an associated call event and initiates a connection between the subscriber and the VMS. The IP notifies the SCP, causing the SCP to instruct the serving MSC to re-establish the connection between the subscriber and the VMS.

  • Publication number: 20020160754
    Abstract: The present invention supports a voice messaging service in a wireless communications system. The wireless communications system comprises a serving mobile switching center (MSC), a service control point (SCP), and a voice messaging system (VMS). A subscriber accesses the VMS through a wireless device to retrieve voice messages that are deposited into the subscriber's voice mailbox. When listening to a voice message that is deposited by a call sender, the subscriber may wish to return a call to the call sender. In such a case, the subscriber initiates the call by invoking a call sender option. The call is established to the call sender's directory number through the serving MSC in concert with the SCP. After completing the call to the call sender, the subscriber may return to the VMS and resume the voice mail session at a desired location corresponding with the subscriber's previous interactions with the VMS.
