If you do receive that result, it means your firewall is either not configured properly or insecure. Having port 5060 open leaves your equipment vulnerable to hacking. If your VoIP service won't work any other way, then you should set your port number to a high/random number between 20000 and 65535.
Is your router as secure as you think it is? Find out with this simple test: http://toao.net/580
