if
(m_outgInviteMsg && !m_outgInviteMsg->isInvalid()
&&
m_outgInviteMsg->isRequest()
&&
(pSession->GetState() != eUnreachable)
&&
(pSession->GetState() != eBusy)
&&
(pSession->GetState() != eDisconnected))
{
std::cout<<"CSipWorker::HangCall: Send
cancel";
resip::SipMessage* pCancelMessage =
resip::Helper::makeCancel(*m_outgInviteMsg);
resip::SharedPtr<resip::SipMessage> pShCancelMessage(pCancelMessage);
m_pDum->send(pShCancelMessage);
m_outgInviteMsg
= NULL;
DebugLog(<< "CSipWorker::HangCall: Send
cancel finished");
}
That's all
application do to signal about tear down the call.(maybe something erong here
too? :) )
Probably I
should change my app architecture to provide ability to send "some
sort of note-to-self to send a CANCEL once a provisional comes in",

What is your app doing to signal its intent to tear down the call?
Best regards,
Byron Campen
Yes,I'm using DUM ...
Any suggestions?
Best regards,

Are you using DUM? I got the impression that this was not the case.
Best regards,
Byron Campen
FYI - DUM should be handling all
of this.

Re: [reSIProcate] Fw: CANCEL before provisional recieved.
If you are going to
freeze the CANCEL transaction, it needs to be done at the TU. So, if your app
decides to end a call, it needs to put some sort of note-to-self to send a
CANCEL once a provisional comes in, and if a final response comes in, to send a
BYE.
Best regards,
Byron Campen
Sending a CANCEL before a provisional response is invalid behavior. Right now,
the stack forges a CANCEL/200 and sends it to the TU, but does not allow the
CANCEL to hit the wire. From here, if B never sends a provisional, the INVITE
transaction will time-out, causing the stack to send a simulated INVITE/408.
However, if B does respond, the call will continue normally. (This is something
a TU must be prepared to handle; just because you get a CANCEL/200 doesn't mean
the remote UAS will end the INVITE transaction.) If B does send a provisional,
but never sends a final response, it is up to A to decide at what point it
wishes to end the transaction. (The TU does this by sending a CANCEL; this will
cause the stack to put a CANCEL on the wire, and start a timer that will cause
the INVITE transaction to be torn down, if it never gets a response)
Best regards,
Byron Campen
Lets try again :)
B sends provisional,but there is large time gap between A INVITEs and B
receives this INVITE, and answers back.
I know that sending CANCEL before provisional is incorrect.
I trying to find "standart" solution for ,maybe, waiting for
provisional or "freeze" CANCEL transaction.
Maybe there is another way to deal with my problem?
Thanks.
Sorry :)
