Dear All,
am facing a problem with my code, am trying to initiate an RTP session. I succeeded with implementation of SIP authentication and registry but i cannot get the RTP steam ?
i would appreciate if someone can review my code and pinpoint the errors am facing.
Enclosed both Class for the RTP and the error am getting.
and would be more appreciated if someone can pinpoint a workable sourcecode or document of a complete SIP and RTP under JAVA J2ME.
package sip_server2;

public class SocketListener extends Thread{
 

   private Form outputForm;

   private boolean shutdownFlag = false;

   private StreamConnectionNotifier notifier;
 

   public SocketListener(Form outputForm){

      this.outputForm = outputForm;

   }
 

  

   private StreamConnectionNotifier createNotifier() throws IOException {

      return (StreamConnectionNotifier)

              Connector.open("socket://192.168.2.56:5062", Connector.READ_WRITE, true);
