Abstract
A voicemail apparatus comprises a voicemail database for storing messages awaiting retrieval by a subscriber, wherein each stored message comprises a message header and message data, the message header including a calling party phone number and calling party network information. A voicemail controller is coupled to the voicemail database for handling an incoming call from a calling party to the subscriber. The voicemail controller compares the calling party phone number of the incoming call with calling party phone numbers of each of the stored messages for the subscriber. If the calling party phone number of the incoming call matches at least one calling party phone number of the stored messages then the incoming call is authenticated by comparing the calling party network information for the incoming call with calling party network information stored for the calling party phone number matching messages. If authenticated, then an option is presented to the calling party of the incoming call to alter those stored message for which the calling party network information matches.
