Hello,
With libpjproject 2.5, my application crashes on every incoming
call with `../src/pjsip-ua/sip_inv.c:2321: pjsip_inv_answer:
Assertion `inv->last_answer' failed.`
For example the example pjsip-apps/src/samples/pjsua2_demo.cpp;
running mainProg1() from that file (adjusted to connect to my
server) and making a call gives me:
-------------------------------------------------------------------------------

------------------------------------------------------------------------
The call handler ist:
-------------------------------------------------------------------------
virtual void onIncomingCall(OnIncomingCallParam &iprm)
{
Call *call = new MyCall(*this, iprm.callId);
CallInfo ci = call->getInfo();
CallOpParam prm;
std::cout << "*** Incoming Call: " << ci.remoteUri << " ["
<< ci.stateText << "]" << std::endl;
calls.push_back(call);
prm.statusCode = (pjsip_status_code)200;
call->answer(prm);
}
---------------------------------------------------------------------------
Any idea what to do here?
thank you
Gabriel
