<p>An intelligent network architecture is employed to handle calls placed to a network subscriber who has changed telephone numbers from an old telephone number to a new telephone number. In a preferred embodiment two call handling procedures are available: a call forwarding procedure, in which calls to the old number are automatically forwarded to the new number; and a messaging procedure, in which an announcement is played to the caller and the caller is invited to leave a message for the subscriber. Through a phone call the subscriber may switch call handling procedures, change the forwarding number, and/or change the messaging announcement. <IMAGE></p> |
