Abstract

A communication system includes a voice subsystem and a multimedia subsystem. The voice subsystem couples to the PSTN and services a voice communication received by the communication system from a caller. The multimedia subsystem couples to the voice subsystem, supports multimedia communications and provides a multimedia interface to the caller upon receipt of the voice communication from the caller. When the call originates from a phone that supports multimedia communications, the multimedia subsystem directs the multimedia interface to the phone but, when the call originates from a phone that does not supports multimedia communications, the multimedia interface is directed to an associated multimedia enabled device. The voice subsystem provides call processing and routing functions as well as messaging functions and extended services. The multimedia subsystem includes an information posting subsystem and an information access subsystem that allow callers to post information and to access information. The multimedia subsystem may also include an application program interface subsystem that allows the caller to initiate execution of an application program on the multimedia subsystem. A universal inbox subsystem that receives, stores and delivers inbox items including voice messages, text messages and video messages via standard interchange protocols and languages. In operating the universal inbox, the multimedia subsystem supports delivery of all inbox items from the universal inbox subsystem to the caller via a standard transfer protocol. In such operation, the universal inbox subsystem converts inbox items to a standard format upon receipt. Methods of operation proceed according to the communication system described herein.
