Re: [reSIProcate] Rejecting media negotiation in case of SDP-less reInvite

[Francis Joanis <francis.joanis@xxxxxxxxx>]

Hi,

I just tested what I think should produce the sequence you mention
(albeit I had reSIProcate on both sides) with the current mainline of
the code.

When I call reject(code), the INVITE transaction is completed (an ACK
with no SDP is sent) then a BYE with the reason "Illegal Sdp
Negotiation" gets sent to B.

This behavior is found in ClientInviteSession:reject(...):

case UAC_Answered:{
         // We received an offer in a 2xx response, and we want to reject it
         // ACK with no body, then send bye
         sendAck();
         SharedPtr<SipMessage> msg = sendBye();
         transition(Terminated);
         mDum.mInviteSessionHandler->onTerminated(getSessionHandle(),
InviteSessionHandler::LocalBye, msg.get());
         break;
      }

Could you retest with the latest release (1.7) and/or the mainline? It
should be working.

Regards,
Francis
