Program aborts and crashes of course. But resip was generating this
log. At least I'm getting this far. I just need to know what this means.
The distant SIP server did NOT get the initial Invite request by the way.
I also found out I don't have to send the OPTIONS command prior to
INVITE for our server.
Program received signal: "SIGABRT".
Program crashed as usual in the parse part.
Stack trace follows (if anyone cares).

partial code that created the "sdp" record is below.
called "Create_sdp" - see my earlier posting.
// Make a "to" NameAddr
NameAddr to(myDestURI);
Data host(to.uri().host());
const char *ipadr = [mBridge getMyIP];
int result = sprintf(sdpstr, "v=0\n\
o=0 0 IN IP4 %s\n\

c=IN IP4 %s\n\

txt = new Data(sdpstr);
hfv = new HeaderFieldValue(txt->data(), txt->size());
Mime type("application", "sdp");
sdp = new SdpContents(hfv, type);
Partial code that sent the invite is here... I commented out the OPTIONS
send.
Our sip server don't need it.
// Create the SDP record with the IP I get from the InfoServer.
myUAC->Create_sdp(myToCString);
char *myRecipient = [recipient UTF8String];
NameAddr toRecipient(myRecipient);
if (!startedCallFlow) {
startedCallFlow = true; // instance var
// Kick off call flow by sending an OPTIONS request then an INVITE
// request from the UAC to the UAS
// Should probably add Allow, Accept, Accept-Encoding,
Accept-Language and Supported
// headers - but this is fine for testing/demonstration
//cout << "UAC: Sending Options Request to UAS." << endl;
//clientDum->send(clientDum->makeOutOfDialogRequest(*from,
OPTIONS, new myAppDialogSet(*clientDum, Data("UAC(OPTIONS)"))));
// Make an invitation Message, by asking the DUM to do it.
cout << "UAC: Sending Invite Request to UAS." << endl;
clientDum->send(clientDum->makeInviteSession(toRecipient,
myUAC->sdp, new myAppDialogSet(*clientDum, "UAC(INVITE)")));
}
So, is it obvious to anyone what it is I'm doing wrong? And why the
parser is gagging on my
"sdp" record?
This is the exact SDP record the Windows client has to send for the
invite...
Does the resip stack not like something about it? I know from sniffing
the Windows application I'm porting from, that the Windows client
sends this exact "sdp". Why is resip rejecting it?
