Abstract: A call-back service is disclosed having reduced post-dial delay. When a caller (12) initiates dialing of an international number of a called party (14), a dialer (28) monitors the dialed digits. Upon detecting a code corresponding to an international number, the dialer immediately launches a call to a node (16) in the caller's local exchange (18) while retaining the digits dialed by the calling party. The node then signals a call-back service platform (24) in a call back-country via a frame relay link (22) to launch a call through an ISDN network (26) back to the dialer. Thereafter, the dialer sends the digits to the call-back service platform which then launches a second call to the called party. The first and second calls are then bridged. By launching the call from the dialer upon detecting an international code in the number dialed by the calling party, the post dial delay is reduced.

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.
