One of our home users has cable Internet with SHAW and their modem is not compatible with VoIP. Even after port forwarding tinkering they still complain constantly. They are also not tech savy so debugging this issue has become a bit of a nightmare. The only thing that seems to work is putting the VoIP phone in the DMZ and I need to know how dangerous this is for us.
The phone GUI is visible on the public and open to potential hackers. We put a 30 character user and admin passcode on the phone to protect it but I am still a bit worried. If hackers were to breach the phone they could probably make calls in this account but that's about it. No?
Any comments?
