Abstract
A method and system for a truly distributed messaging architecture based on existing LAN and PC technologies. A caller using one multi-media enabled PC (MPC) attempts to connect to a called MPC via a LAN or other digital data communication network. If the called MPC is in a receive mode but no one answers after a preset time, a prepared greeting message from the called MPC (e.g., an audio or audiovisual data file) is transmitted via the LAN to the calling MPC and played to the caller. The caller may then record an audio or audiovisual outgoing message for the called MPC. The outgoing message is stored in an 'Outbox' for the caller, and a LAN message from the calling MPC starts a 'message waiting' indicator on the called MPC. Whenever the called party is ready to receive waiting messages, that party can start an application which shows envelope information for such messages. The recipient can then retrieve any outgoing message stored in the Outbox for the calling MPC, and play back such messages. The invention can also be used for 'call screening' by called parties, for sending audio or audiovisual information from a calling MPC over a LAN to many called MPCs simultaneously, and for 'conference' calls.
