The idea of voice mail is very simple. Web voice mail application creates the text and voice messages and send them to web server via HTTP by POST method. On the server side the server scripts create usual e-mail message body with text message and with link to Mp3 file (voice message). Mp3 file is stored on the server. Server script passes the e-mail message body to Mail Transfer Agent, which send it to recepient. Recepient receives the e-mail message with text and link to Mp3 file and downloads and/or play Mp3 file. Also, it is possible to save recorded audio file on the client computer and open it from there. To playback the recorded MP3 audio from the server the recording applet works in the streaming mode.
