Question

I am creating a J2ME real time streaming audio player with RTP and through SIP connection. Also I am new for these things. I want to take look deeply those things. If any one know a good working sample code demonstrating an audio player streaming with RTP (That means how to send a REGISTER message to the server through SIP to get registered and send an INVITE message and get the response & play). Please let me know, highly appreciated.

Also I looked here

if

My server port is 6060
ip 111.111.111.1
id is myid password 123

Have I used the code correctly? If I am wrong, please make me correct.

public void doRegister(String username, String password, String realm) {

  SipClientConnection scc = null;  
  SipConnectionNotifier scn = null;  
  String contact = null;    
  try {   
      scn = (SipConnectionNotifier) Connector.open("sip:5080");   
      contact = new String("sip:myid:123@"+scn.getLocalAddress()+":"+scn.getLocalPort());   
      scc = (SipClientConnection) Connector.open("sip:111.111.111.1+"transport=tcp")  ; 
      scc.initRequest("REGISTER", scn);  
      scc.setHeader("From", "sip:myid:123@"+scn.getLocalAddress()+":5080");  
      scc.setHeader("To", "sip:myid:123@111.111.111.1");  
      scc.setHeader("Contact", contact);  
      scc.send();  
      boolean handled = false;  
      int scode = 0;        
      while(!handled) {
          SipHeader sh; 
          scc.receive(30000);
          scode = scc.getStatusCode();
          switch(scode){  
              case 401:
                  sh = new SipHeader("WWW-Authenticate",
                     scc.getHeader("WWW-Authenticate"));
                  realm = sh.getParameter("realm");                
                  scc.setCredentials(username, password, realm);
                  break;

              case 407:
                  sh = new SipHeader("Proxy-Authenticate", 
                  scc.getHeader("Proxy-Authenticate"));
                  realm = sh.getParameter("realm");                
                  scc.setCredentials(username, password, realm);
                  break;

              case 200: 
                  handled = true;
                  break;
              default:  
                handled = true;
          }  
      }
      scc.close();
  } catch(Exception ex) {
      // handle Exceptions
  }
 }

I got a respond with 180 Rigging message. Also let me know what is realm here. scc.setCredentials(username, password, realm);
