title: Jain-Sip Authentication
body: <p>I'm working with the Jain Sip library, trying to create a connection to an asterisk server.  I've been working with the textclient example app from this page:
  <a href="http://www.oracle.com/technetwork/articles/entarch/introduction-jain-sip-090386.html" rel="noreferrer">http://www.oracle.com/technetwork/articles/entarch/introduction-jain-sip-090386.html</a> </p>
  
  <p>but this doesn't actually authenticate with the server.  I can send messages to users on the server, but I normally require a user/password authentication on the server.  </p>
  
  <p>As far as I can tell I have to use the "javax.sip.OUTBOUND_PROXY" property, but I can't find any documentation on how to set a username or password.  Has anyone else had any success with this?</p>
