Abstract
A communications system uses a World Wide Web (Web) server to provide multimedia messaging functions over the Internet. Multimedia workstations are interconnected via the public switched telephone network (PSTN). Parties are provided with multimedia mailboxes on message servers that are connected to the PSTN and the Internet. In order to identify the message server on which a called party's mailbox is located, the Web server provides the multimedia number of the called party's message server when a call is made. In addition, the Web server provides the multimedia number of the called party. When a multimedia call is unanswered, the system uses the multimedia number of the message server and the called party multimedia number provided by the Web server to record and store a message for the called party in the called party's mailbox.
