While sending a call to the Park Server via consultative transfer, I notice that after the Park Server receives the second INVITE (with Replaces, from the parkee, replacing the first INVITE from the parker), the Park Server cannot get the request-URI. The code it uses is:

Initial processing of the TAO message:

if (rMsg.getMsgType() == OsMsg::TAO_MSG &&
       rMsg.getMsgSubType() == TaoMessage::EVENT)
   {
      TaoMessage* taoMessage = (TaoMessage*)&rMsg;

int taoEventId = taoMessage->getTaoObjHandle();
      UtlString argList(taoMessage->getArgList());
      TaoString arg(argList, TAOMESSAGE_DELIMITER);

if (OsSysLog::willLog(FAC_PARK, PRI_DEBUG))
      {
         // Dump the contents of the Tao message.
         dumpTaoMessageArgs(taoEventId, arg) ;
      }
      UtlBoolean localConnection = atoi(arg[TAO_OFFER_PARAM_LOCAL_CONNECTION]);
      UtlString callId = arg[TAO_OFFER_PARAM_CALLID] ;
      UtlString address = arg[TAO_OFFER_PARAM_ADDRESS] ;

Separating the CONNECTION_ESTABLISHED messages:

case PtEvent::CONNECTION_ESTABLISHED:
            if (localConnection)
            {
               OsSysLog::add(FAC_PARK, PRI_DEBUG, "OrbitListener::handleMessage - Call established: callId '%s', address: '%s'",
                             callId.data(), address.data());
               
ParkedCallObject* pThisCall = NULL;
               // CallId at this point is either the callId of a normal call or the original callId
               // of a second leg of a transfer.

// Test if this is a call retrieval operation
               if (!isCallRetrievalInvite(callId.data(), address.data()))

Determining the request URI of the message:

bool OrbitListener::isCallRetrievalInvite(const char* callId,
                                          const char* address)
{
   bool bRet = false;
   
// Retrieve the request URI
   SipDialog dialog;
   mpCallManager->getSipDialog(callId,
                               address,
                               dialog);
   UtlString request;
   dialog.getRemoteRequestUri(request);
                               
OsSysLog::add(FAC_PARK, PRI_DEBUG, "OrbitListener::isCallRetrievalInvite remote request URI %s", request.data());

The typical log contents are:
