SYSTEM AND METHOD FOR UNIFIED MESSAGING IN INTER/INTRANET TELEPHONY

摘要

A network telephony system is provided which enables unified messaging services. The system generally includes at least one user agent ( 102,104 ) operatively coupled to a data network ( 106 ) and a signalling server operatively coupled to the data network ( 106 ). The user agents ( 102,104 ) are telephony endpoints, such as standalone Internet telephony appliances or personal computers with appropriate telephony software. A messaging server ( 110 ) is provided which is operatively coupled to the data network ( 106 ) and is responsive to the signaling server ( 108 ). The system also includes a media server ( 112 A, 112 B) which is operatively coupled to the network and includes computer data storage media for storing message files. The media server is responsive to the messaging server ( 110 ) and, on occurrence of a message condition, is directly accessible to a calling party to store a message file for subsequent retrieval by a called party.
