AnnexAFormatelementofservicedefinitions Abstract
Covers the general principles and basic operational requirements of the voice-mail store-and-forward services given by service providers by means of computer-controlled voice-mail systems and Voice-mail Store-and-Forward Units (Voice SFU). Defines minimum service requirements for permitting international extension of the service, which is achieved by interconnecting one or more other Voice SFUs, across national boundaries by means of automated transit facilities for delivering and transferring voice-mail messages.
