SIP SUBSCRIBE problem

[teemuvr]

Hi!

I have problems sending SUBSCRIBE for presence..
Following code is executed ok, but nothing is received at the server end. Can someone help me by pointing the problem?

CSIPMessageElements* msgElem = CSIPMessageElements::NewL();
CleanupStack::PushL( msgElem );

//Get the current connection
CSIPConnection& conn = ConnectionL();

// Create user header array
RPointerArray<CSIPHeaderBase>* userHeadersArr = new(ELeave)RPointerArray<CSIPHeaderBase>;
CleanupStack::PushL( userHeadersArr );

// Create Expires Header
CSIPExpiresHeader* expiresHdr = new (ELeave)CSIPExpiresHeader(60);

CleanupStack::PushL( expiresHdr );

userHeadersArr->Append(expiresHdr);
CleanupStack::Pop( expiresHdr );

// Set the User Headers
msgElem->SetUserHeadersL(*userHeadersArr);
CleanupStack::Pop( userHeadersArr );

//Create Event Header
CSIPEventHeader* eventHdr = CSIPEventHeader::NewL(_L8("PRESENCE"));
CleanupStack::PushL( eventHdr );
userHeadersArr->Append(eventHdr);

// create an object for refresh
CSIPRefresh* iRefresh = CSIPRefresh::NewL();
CleanupStack::PushL( iRefresh );

//Getting sip username (AOR)
const TDesC8* aor = NULL;
iProfile->GetParameter( KSIPUserAor, aor );

//Creating and setting "to" header
CSIPAddress* toAddress =CSIPAddress:ecodeL(*aor);
CleanupStack::PushL(toAddress);
CSIPToHeader* toHeader = CSIPToHeader::NewL(toAddress);
CleanupStack::Pop(toAddress);
CleanupStack::PushL(toHeader);

//Creating and setting "from" header
CSIPAddress* addr = CSIPAddress:ecodeL( *aor );
CleanupStack::PushL( addr );
CSIPFromHeader* fromHeader = CSIPFromHeader::NewL( addr );
CleanupStack::Pop( addr );
CleanupStack::PushL(fromHeader);

TBuf8<128> contact;
_LIT8(kat,"@");
_LIT8(klocal, "@LOCALHOST");
TInt iNameEnd = aor->Find(kat);
contact.Copy(aor->Ptr(), iNameEnd);
contact.Append(klocal);
CSIPContactHeader* contactHeader = CSIPContactHeader::NewL(CSIPAddress:ecodeL(contact));
CleanupStack::PushL(contactHeader);

CUri8* uri8 = ConvertToUri8LC( *aor );

// create an object for CSIPSubscribeAssoc

iSubscribeDialogAssoc = CSIPSubscribeDialogAssoc::NewL
(conn, fromHeader, uri8, eventHdr, toHeader, contactHeader);

CleanupStack::Pop( ); //uri 8

CleanupStack::Pop( contactHeader );
CleanupStack::Pop( fromHeader );
CleanupStack::Pop( toHeader );

delete iClientTx;
TRAPD(err,iClientTx = iSubscribeDialogAssoc->SendSubscribeL
(msgElem, iRefresh));

if(err!=KErrNone)
{

User::Leave(err);
}

CleanupStack::Pop( iRefresh );

CleanupStack::Pop( eventHdr );
CleanupStack::Pop( msgElem );

Thank you!

Hi Teemu!

Can't see anything horrobly wrong with the code, so before checking it more carefully, please answer few questions.

You say problem is "nothing is received at the server end". How you verified this? Have you checked using network sniffing tools (like ethereal/wireshark) that sip-stack really does not send anything to network? Before trying SUBSCRIBE, do you send REGISTER? Can you see that on sniffer? And finally, you have waited sip-connection to be active? And you are 100% sure that SendSubscribeL does not leave with errorcode?

There are be plenty of working SIP examples,
maybe test if those work to see if there really is a problem in your code.

Hi,

Usually this problem may arise from not including the "loose routing" option on the to field. The symbian sip stack will then send the request to the resolved domain id rather then address you mentioned. I had a similar problem when doing sip register. May be you are facing the same problem with subscribe requests. Are you sure that your SIP Register command was completed successfully.

Hi!

Thank you all very much for answering and sorry for little delay, but I was on vacations for few days..

Yes, I am sending register before subscribe. And this registration is successful. I can see it from the SIP-settings of the device that I'm using.
For various reasons I'm not able to run my program on emulator so I have to use it in real device. (For example, using ethernet in emulator seems to be pain in the ***).
And actually only thing why I know that nothing is received is server side is because I'm observing log of my SIP server.
In one of the versions I had debug messages that verified code reaching end of this function and not going to if(err!=KErrNone)
{}.
And yes, I tested that SIP connection is active before sending SUBSCRIBE.
And yes, I have loose routing enabled in SIP-settings, if that's what vaibhavjain ment?

BR, Teemu
