Have anyone used Jain Sip to do a Sip registration on Android?

I'm currently using Jain Sip on Android and I'm trying to get a SIP registration working.

I can put the registration SIP message together ok but after sending the message it seems to just get sent back to my application and my applications processRequest() method is run.

Here is the code I'm using :

public void init(TextView tv) throws Exception {
SipFactory sipFactory = null;
sipStack = null;
sipFactory = SipFactory.getInstance();
sipFactory.setPathName("gov.nist");
Properties properties = new Properties();
properties.setProperty("javax.sip.OUTBOUND_PROXY", getLocalIpAddress()+":8002" + "/"
+ ListeningPoint.UDP);
properties.setProperty("javax.sip.STACK_NAME", "Sip Test");
// Create SipStack object
sipStack = sipFactory.createSipStack(properties);
tv.setText("sipStack = " + sipStack);
headerFactory = sipFactory.createHeaderFactory();
addressFactory = sipFactory.createAddressFactory();
messageFactory = sipFactory.createMessageFactory();
lp = sipStack.createListeningPoint(getLocalIpAddress(),
8002, ListeningPoint.UDP);

sipProvider = sipStack.createSipProvider(lp);
sipOnOffFlag = true;
tv.append("\n jain sip stack started on " + getLocalIpAddress() + ":" + myPort + "/" + ListeningPoint.UDP);
sipProvider.addSipListener(this);

String fromName = "019078020";
String fromSipAddress = "216.234.148.28";
String fromDisplayName = "Donal";

String toSipAddress = "216.234.148.28";
String toUser = "16784732970";
String toDisplayName = "Server";

// create >From Header
SipURI fromAddress = addressFactory.createSipURI(fromName,
getLocalIpAddress());

Address fromNameAddress = addressFactory.createAddress(fromAddress);
fromNameAddress.setDisplayName(fromDisplayName);
FromHeader fromHeader = headerFactory.createFromHeader(
fromNameAddress, null);

// create To Header
SipURI toAddress = addressFactory
.createSipURI(toUser, toSipAddress);
Address toNameAddress = addressFactory.createAddress(toAddress);
toNameAddress.setDisplayName(toDisplayName);
ToHeader toHeader = headerFactory.createToHeader(toNameAddress,
null);

// create Request URI
SipURI requestURI = addressFactory.createSipURI(toUser,
"216.234.148.28");

// Create ViaHeaders

List<ViaHeader> viaHeaders = new ArrayList<ViaHeader>();
String ipAddress = lp.getIPAddress();
ViaHeader viaHeader = headerFactory.createViaHeader(ipAddress,
lp.getPort(),
lp.getTransport(), null);

// add via headers
viaHeaders.add(viaHeader);

// Create ContentTypeHeader
ContentTypeHeader contentTypeHeader = headerFactory
.createContentTypeHeader("application", "sdp");

// Create a new CallId header
CallIdHeader callIdHeader = sipProvider.getNewCallId();

// Create a new Cseq header
CSeqHeader cSeqHeader = headerFactory.createCSeqHeader(1L,
Request.REGISTER);

// Create a new MaxForwardsHeader
MaxForwardsHeader maxForwards = headerFactory
.createMaxForwardsHeader(70);

// Create the request.
Request request = messageFactory.createRequest(requestURI,
Request.REGISTER, callIdHeader, cSeqHeader, fromHeader,
toHeader, viaHeaders, maxForwards);
// Create contact headers

SipURI contactUrl = addressFactory.createSipURI(fromName, getLocalIpAddress());
contactUrl.setPort(8002);
contactUrl.setLrParam();

// Create the contact name address.
SipURI contactURI = addressFactory.createSipURI(fromName, getLocalIpAddress());
contactURI.setPort(sipProvider.getListeningPoint(lp.getTransport())
.getPort());

Address contactAddress = addressFactory.createAddress(contactURI);

// Add the contact address.
contactAddress.setDisplayName(fromName);

contactHeader = headerFactory.createContactHeader(contactAddress);
request.addHeader(contactHeader);

// You can add extension headers of your own making
// to the outgoing SIP request.
// Add the extension header.
Header extensionHeader = headerFactory.createHeader("Expires",
"0");
request.addHeader(extensionHeader);

Log.d("SIP", "" + request.toString());
// Create the client transaction.
registerTid = sipProvider.getNewClientTransaction(request);

// send the request out.
registerTid.sendRequest();

dialog = registerTid.getDialog();
}

So the message gets built ok but when sendRequest() is run it doesn't appear to get sent to the server but rather back to my application and the applications processRequest method is run.

Should I be doing something extra with inviteTid or the dialog?

Do I need to create a socket or something to sent the request out?
