I haven't the time to test this out, and I've never had any luck with Java apps of any type, but this looks interesting: https://sip-communicator.dev.java.net/ for the truly foolhardy, go right to a browser launch (linux, windows supported): http://clarinet.u-strasbg.fr/sip-communicator/download/webstart/sip-communicator.jnlp I tried with my Mac, and (amazingly!) the application launched, but none of the menu items were selectable and I couldn't change or "do" anything to the list of demo users in the presence list. I don't have the time to muck with it, but looks like something that would be worthwhile to test out against Asterisk. Perhaps someone can compile and reply to the list with their experiences? This looks pretty sharply written, and the fact I had success with a Java app at all is a miracle, so maybe on a different platform it works as expected. JT
