Abstract
The present invention relates to a method for providing delivery confirmation of message deliveries made in a telephone network. In a network of the present invention, subscriber-specific information is maintained to determine whether a subscriber has a message delivery service available that allows delivery of subscriber-specific messages. Upon delivery of confirmation of the availability of a subscriber message delivery service, a confirmation addressed to a subscriber is routed to the message delivery service on the basis of the subscriber-specific information. This and other aspects of the method of the present invention reduce extra network traffic that cannot be charged, and reduces the complications associated with other telephone network systems that require information to be provided by pushbutton dial to the system.
