How to send a SIP MESSAGE request ?

[big_vj]

Hi All,

How to send a SIP MESSAGE request ? I have registered 2 user-agents successfully and now i want to send a MESSAGE from one to another. Here is what am doing... I create a CSIPRequestElements objects with the AOR of the recipient, then i retrieve the CSIPMessageElements object from it. After this i set the method and content for the CSIPMessageElements object and then send it using the active connection. The problem is that at runtime its giving me a KErrArgument(-6, Bad Request) error in the SendRequestL(...) call. Can someone please tell me which argument is wrong or if i need to put in any more fields in the CSIPMessageElements object ?


// code starts ...

CSIPAddress* addr = CSIPAddress:ecodeL(_L8("sip:user2@mydomain.com"));
CSIPToHeader* aor = CSIPToHeader::NewL(addr);

CSIPRequestElements *elements = CSIPRequestElements::NewL(aor);
elements->SetMethodL(_L8("MESSAGE"));

CSIPMessageElements& msgElements = elements->MessageElements();

HBufC8* g = HBufC8::NewL(10);
g->Des().Append(_L8("Hi there!"));
CSIPContentTypeHeader* cType=CSIPContentTypeHeader::NewL(_L8("text"), _L8("plain")); // is this right ?
msgElements.SetContentL(g, cType);

CSIPClientTransaction* sipClientTransaction = iConnection->SendRequestL(elements);

// code ends.


And.. on the receiving side which callback method will be invoked when the message is received ?

Someone please help, this is really urgent for me..

Thanx in advance,

hello,

the chipflip example has a section on it's sip engine project (transactionsstates i think) which i think can help u. a bad request is usually generated when your message doesnt have all the necessary requirements (i.e. headers,sdp,etc) or contains a header with a wrong value.

u can also refer to the RFC specs of the SIP for further reading.

happy programming!

Thanks SilentSmirk!

I tried to go thru Chipflip, but its architecturing seems awfully complicated to me! Maybe becoz am a newbie! Anyway i got it rolling after adding "" to the list of accept types in the ecom plugin's resource file.

I think it's your sip server who is sending the bad request response.

I have similar code, but i'm not succeeding ind sending the message request.
I'm using the SIPExample as base code and I'm able to send Register and Invite, but when I try to send the Message request in the "ProfileRegistrationStatusChanged" after succesfully enabling the profile. The code that I'm using is:

CSIPAddress* toAddress = CSIPAddress:ecodeL(_L8("sippponent@opponentdomain.com"));
CleanupStack::PushL(toAddress);
CSIPToHeader* toHeader = CSIPToHeader::NewL(toAddress);
CleanupStack::Pop(toAddress);
CleanupStack::PushL(toHeader);

CSIPRequestElements *elements = CSIPRequestElements::NewL(toHeader);
elements->SetMethodL(_L8("MESSAGE"));
CSIPClientTransaction* sipClientTransaction = iConnection->SendRequestL(elements);

Anybody has any idea of what might be wrong?

Thanks
