Android Jain Sip - Sip Registration?

Question

Hi all,

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?

Answer 1

Thanks Nos.

Removing the outbound proxy altogether has worked

Answer 2

So, this did work, right? What about de-registration?
