RE: [reSIProcate] SipMessage and RTP

[Scott Godin <slgodin@xxxxxxxxxxxx>]

Oops I misunderstood - I thought you wanted to store the SDP Contents from
the invite - not create an SDP response.  

By the way - you shouldn't modify the To/From fields like you are doing
  response->header(h_To) = msg->header(h_From);
  response->header(h_From) = msg->header(h_To);

The To and From in a response is always supposed to be the same as the
request.  The message returned from makeResponse should be right already.

I figured it out but did it slightly differently.

void SipHandler::handleInvite(SipMessage* msg) {
  assert(isInvite(msg));
  NameAddr addr(mLocalUri);
  NameAddrs contact;

  // sendResponse(msg,200);

  SipMessage* response = resip::Helper::makeResponse(*msg, 200);
  SdpContents* contents = createSdpContents();
  response->setContents(contents);
  contact.push_front(addr);

  response->header(h_Contacts) = contact;
  response->header(h_To) = msg->header(h_From);
  response->header(h_From) = msg->header(h_To);
  send(*response);
  delete response;
  delete contents;
}

SdpContents* SipHandler::createSdpContents () {
  SdpContents* sdp = new SdpContents();
  sdp->session() = createSdpContentsSession();
  return sdp;
}

SdpContents::Session SipHandler::createSdpContentsSession () {
  SdpContents::Session session;
  Data ip(mLocalUri.host());

  resip::SdpContents::Session::Origin origin = session.origin();
  origin.setAddress(ip);
  origin.user() = "obr3";

  resip::SdpContents::Session::Connection
con((resip::SdpContents::AddrType)1,ip);

  session.addMedium(createMedium());
  session.name() = "mysession";
  session.connection() = con;
  session.origin() = origin;

  return session;
}

SdpContents::Session::Medium SipHandler::createMedium () {
  Data name("audio");
  Data protocol("RTP/AVP");
  SdpContents::Session::Medium med(name,5004,0,protocol);

  med.addCodec(resip::SdpContents::Session::Codec::ULaw_8000);
  med.addCodec(resip::SdpContents::Session::Codec::ALaw_8000);
  med.addCodec(resip::SdpContents::Session::Codec::G729_8000);
  med.addCodec(resip::SdpContents::Session::Codec::TelephoneEvent);
  return med;
}
