URGEND: accessing a voicemodem and playing *.wav file

[guenter]

I have to develop an notification system which dials an Phonenumber over an voicemodem and plays an *.wav ( or any other filetype ) so that the person who gets called can hear the message .

My Problem is
1. how to get a connection to the modem and
2. how to play the soundfile over the modem

I've read to access the modem there is the javax.comm Package.
But how do I manage playing the file ?

any help or suggestions welcome

thanks
