Receiving transaction termination notifications

A TU (transaction user) can register to be notified of transaction terminations. To enable it, call SipStack::registerForTransactionTermination() on your SipStack object.

When transactions terminate, the SipStack will pass a TransactionTerminated TransactionMessage up to the TU through the TUfifo. This is retrieved by the TU through a call to SipStack::receiveAny(). The message indicates if the transaction is client or server and also provides the associated transaction id.

      TransactionTerminated(const Data& tid, bool isClient, TransactionUser* tu) : 
         mTransactionId(tid), 
         mIsClient(isClient)
      {
         setTransactionUser(tu);         
      }
      virtual const Data& getTransactionId() const { return mTransactionId; }
      virtual bool isClientTransaction() const { return mIsClient; }
      virtual std::ostream& encode(std::ostream& strm) const { return encodeBrief(strm); }
      virtual std::ostream& encodeBrief(std::ostream& str) const;
      
      Data mTransactionId;
      bool mIsClient;
 };
