Abstract
An adjunct message system, coupled to a global telecommunications network, provides a roaming subscriber with roaming access to messages left at the subscriber's home mailbox by transferring such messages to a temporary roaming mailbox at a roaming node when the subscriber first calls to retrieve his/her messages. In addition, messages left at any node in the system will be transferred to the subscriber's home node. In both cases, international voice transport costs will be saved.
