Abstract: PURPOSE: A method for supporting a voice mail using an internet phone gateway is provided for leaving voice messages using the internet phone gateway system when a receiver is unavailable. CONSTITUTION: When a user A calls a user B, a protocol processor(24A) transmits and receives a control data between an internet phone gateway A(22) connected with the user A and an internet phone gateway B(24) connected with an opponent user B and prepares a communication to match the opponent communication system and a communication protocol. A controller(24B) searches the telephone number of the user B requested by the user A from a gatekeeper(26). If the telephone number of the user B is not listed in the gatekeeper(26), the controller(24B) disconnects the communication. If the telephone number of the user B exists in the gatekeeper(26), a call request signal is transmitted to the telephone(27) of the user B through the telephone interface unit(24E).
