Mobile Record the voice as one buffer or file in AMR codec.</FONT></DIV> <DIV><FONT size=2>    2. Client A, send this data to Client B （maybe put the data into special message stanza）, the data should be sent to the server first (as all message will through server transfer to another client)</FONT></DIV> <DIV><FONT size=2>    3. The XMPP server will not directly send the data to Client B first, but story the data, and notify the Client B, now there is one voice data coming to you(including Client As's JID, time stamp, and maybe voice message ID, etc)</FONT></DIV> <DIV><FONT size=2>    4. Client B if want to receive the voice message, then send the request to the XMPP server, then the XMPP server will push the voice data to Client B.</FONT></DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2>    This is our idea, but we didn't know how we can do and use which protocols. is anybody can help us. Thanks very much.</FONT></DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2>Regards</FONT></DIV> <DIV><FONT size=2>Charles</FONT></DIV> <DIV><FONT size=2></FONT> </DIV></BODY></HTML>
