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.
