Examples of javax.sip.Dialog.sendAck()

javax.sip.Dialog.sendAck()
Sends ACK Request to the remote party of this dialog. This method implies that the application is functioning as User Agent Client hence the underlying SipProvider acts statefully. This method does not increment the local sequence number. @param ackRequest -the new ACK Request message to send. @throws SipException if implementation cannot send the ACK Request for any reason

      CSeqHeader cseq = (CSeqHeader) responseEvent.getResponse().getHeader(CSeqHeader.NAME);
      try{
        Dialog dialog = responseEvent.getClientTransaction().getDialog();
        Request ack = dialog.createAck(cseq.getSeqNumber());
        //System.out.println("Ack sent");
        dialog.sendAck(ack);
      }catch (SipException e) {
        e.printStackTrace();
        System.err.println(e.getMessage());
      }catch (InvalidArgumentException e) {
        e.printStackTrace();
