Re: [reSIProcate] generate a 183 with SDP on the server side
Thanks for your suggestion, but when I call provideAnswer () method like this:
------------------------------------------------------
mSis->provideAnswer (somesdp);
mSis->provisional(183);
-----------------------------------------------------
an exception will throwed and a warning message will be printed like this:
"Can't provideAnswer when not in Connected state",
which is located on InviteSession.cxx.
It seems that provideAnswer() method can't not be called here.So what will I do?
