Re: [reSIProcate] generate a 183 with SDP on the server side
Thanks for your help!I have download the newest version from
svn,The 183 message with SDP have been send successfully.but I have a
new problem.
After send a 183 message with SDP. I want to connect the call, so
I call accept() method.But I see that the 200 message still have a SDP
body.
The desired senario should be as following:
Client Server
F1:INVITE(offer)
|--------------------------------->|
| F2:100 TRYING |
|<---------------------------------|
| F3:183 session process(answer) |
|<---------------------------------|
| F4:200 OK (without SDP)|
|<---------------------------------|
|.............
|
I use the following code(come from the basiccall.cxx) to do this.
------------------------------------------------------------------------------------------
virtual void onOffer(InviteSessionHandle is, const SipMessage& msg,
const SdpContents& sdp)
{
InfoLog( << name << ": InviteSession-onOffer(SDP)" );
//ServerInviteSessionHandle mSis
is->provideAnswer(*this->sdp);
mSis->provisional(183);
........................
//some operation here.
mSis->accept();
}
After call accept() method, the stack send a 200 message with SDP body.
Can anyone give me some suggestions that how I can elimanite the SDP
body in 200 message?
Thanks!!!
