With the sip port, there is a carrier-exclusive option that will make the system reject and sip packets that don't come from the server defined in the carrier options (or that resolves by a DNS lookup in the case of a dns name for the proxy/auth server address's)

Indeed, you can change the admin account password via the web interface, but the root account is still lurking on the system. I've not checked anything after 4.6 to see if the root account password was changed along with the admin password.
It's shocking how bad the implementation is if some random packets to the IP stack can cause the entire system to fall over, there are other implementaion fails too - not being able to install certificates to prevent man-in-the-middle attacks is near the top of the list.

I too have come across this issue, with a client that has 5 7100's and 1 7200S, I'm proposing a VPN solution to the client, they only use SPNet between sites so SIP trunks are not an issue, I'm planning on using PC Engines ALIX 2D13 single board computers at all locations, running pfSense and utilizing OpenVPN for the tunnels. I've successfully run about 8 tunnels at a time on these little router boxes without issue.... The idea being, make it so the Samsungs are only reachable from WITHIN the VPN tunnels, NO Port Forwards. For remote admin access, I'll simply enable the PPTP VPN server on each of the firewalls, so the only way to access the Samsung switches from outside would be to establish a PPTP VPN session with the router at that site.
