Sip Registration help

Atomic Pineapple

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?

I've never used JAIN SIP so this could be wrong but the problem may be

properties.setProperty("javax.sip.OUTBOUND_PROXY", getLocalIpAddress()+":8002" + "/"
+ ListeningPoint.UDP);

In SIP terms the outbound proxy normally refers to the server you are sending to so should probably be the external server's address and port instead of your own.

Thanks Matrim, I had just come back here to say that line was the problem

Removing it completely has fixed it

argh,

have a new problem.

I can register fine but when I go to re-register the new call id method throws a null pointer exception

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

Error:

02-11 09:40:59.877: WARN/System.err(612): java.lang.NullPointerException
02-11 09:40:59.877: WARN/System.err(612): at gov.nist.javax.sip.SipProviderImpl.getNewCallId(SipProviderImpl.java:230)

Anyone come know why it would be null?


EDIT:

I figured out that the CallId should be the same with a registration with the server and not a new one each time so that fixed that.

But Now I'm getting a nullpointer here:

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

Error:

02-11 11:04:08.727: WARN/System.err(1178): java.lang.NullPointerException


Anyone any ideas?

EDIT:

Fixed that one too.

I now have a null pointer exception from this line:

inviteTid = sipProvider.getNewClientTransaction(request);

And really cant figure this one out
