Using components such as intermediate short message service service centers and active subscriber identity systems, it is possible to deliver a message to a subscriber at a number different from the number which was entered by the message's sender at the time the message was sent. These components can also be used to deliver the message in the event that the sender is unavailable at the time the message is originally sent. Communications between components can be performed in a variety of manners, including using proprietary IP protocols, and the components can be configured to take responsibility for retrying message delivery by providing a delivery confirmation once the message reaches them, rather than providing delivery confirmation once it reaches its ultimate recipient. |
