title: Java VOIP framework
body: <p>I have standalone application written on Java/SWT. And now i required to implement softphone functionality in this app.  Is there any ready to use VOIP framework written fully on java, which let me develop softphone fast without messing with low-level sip/rtp packets and media codecs?</p>
  
  <p>So far i tried:  </p>
  
  <ul>
  <li><code>jain-sip + jmf</code>: sound quality is real horrible  </li>
  <li><code>c-library pjsip with jni</code>: it did the trick, but library doesn't yet support 64bit and jni is such pain with this random jvm crashes.</li>
  </ul>
  
  <p>Now i am studying peers library, but maybe there is some easy to use frameworks?</p>
  
  <p>P.S. application should work with asterisk, and able to manage calls(transferring, conference e.t.c)</p>
