[reSIProcate-users] 200 response after BYE.

From: Gustavo Sícoli <sic.thesage@xxxxxxxxx>
Date: Tue, 31 Aug 2010 16:48:45 -0300

Hello,

I've alterated DUM behavior to work with my B2B app and it is not automatically sending 200 after receiving a BYE anymore. Instead, I created a new callback "onTerminatedConfirmed" to be called when I receive a 200 message from B so I can send a 200 to A. To send this 200 message I use DUM::send(my200), the problem is that for some reason my message is not sent, it is instead discarded. Could you help me understanding why is it being discarded?

follows a simplified sample of how I'm building/sending the message. Note that caller is a struct I stored some usefull information and that the response is constructed based on response I receive from B side, therefore some parameters has to be altered to match A side:
   NameAddr contact;
   contact.uri() = dum->getMasterProfile()->getPublicGruu();
   Helper::makeResponse(rsp, msg, 200,contact);
   rsp.remove(h_To);
   rsp.remove(h_From);

   rsp->header(h_To) = caller->to;
   rsp->header(h_From) = caller->from;
   rsp->header(h_CallId).value() = caller->mSis->getCallId();
   rsp->header(h_Vias).front().remove(p_branch);
   rsp->header(h_Vias).front().param(p_branch) = caller->via.param(p_branch);

   dum->send(rsp);

Here is debug output from the moment I receive BYE from A side:
