    There are a few Java API for working with telephone applications, like JTAPI but I think those assume VOIP types of phones.
    I'm not even sure they still make 'voice' modems built into data modems any more.
    But my theory is, you could get one of those digium cards from digium (a pci card that provides a POTS land line termination, and then run asterisk PBX on your box, and then a SIP peer, for which you would connect a SIP soft phone to.

    Note however, this is a multi-product and not just java solution.
    Im sure if there was a desire to make a single java-to-voice-modem telephone application, it would need to make use of native system libraries and OS device drivers thru JNI, but I don't now of any direct applications like that.

    And also I think it's possible to built up VOIP communication using Java Sound API as well, full-duplex may be. Check on the Suns' official web site, you can find the link.
