[reSIProcate] 180 Ringing and 200 OK messages with incorrect port?

[Dien Ba Quang]

Hi,
I have problem with 180 Ringing and 200 OK messages. When I received INVITE
message, the callback function : onNewSession(ServerInviteSessionHandle sis,
InviteSession::OfferAnswerType oat, const SipMessage& msg) is called.
But two message 180 Ringing and 200 OK didn't send to Sip server (SIPX 3.6)
with the correct port 5060, they used a random port (37570, ...). Do you
know how to make them send to correct port 5060?

Below is my source code of the callback function:

void
TestUac::onNewSession(ServerInviteSessionHandle sis,
InviteSession::OfferAnswerType oat, const SipMessage& msg)
{
    cout << name << ": ServerInviteSession-onNewSession - " << msg.brief()
<< endl;
    cout << name << ": Sending 180 response." << endl;
    mSis = sis;
//sis->provisional(100);
    sis->provisional(180);
    SdpContents* msdp = dynamic_cast<SdpContents*>(msg.getContents());
sis->provideAnswer(*msdp);
sis->accept();
_status = 5; // server receive invite and sended 200 OK with SDP
Data IpAddress = msdp->session().connection().getAddress();
int port = msdp->session().media().begin()->port();
OnInviteResult(&_status, (char*)IpAddress.c_str(), &port);
}


Any help would be appreciated.
