This forum is for general beginner Java questions. I don't think VoIP qualifies as a beginner question. You should take a look at our other forums and choose one with a topic that better fits your question. If there is no other specialized forum where this fits, you should ask your question in the Java in General (advanced) forum.
p.s. This is a long way of saying I don't know. Sorry I can't be of much more help. [ June 19, 2005: Message edited by: Layne Lund ]
