Even though a trixbox system is a phone system, it is still a basic computer system like any other. One of the problems that we face is that extensions and VoIP service providers typically come into the system over the open Internet; this means that certain aspects of our system are wide open to the outside world. During the week that this article was written, several new scripts came out that allowed people to scan machines over the Internet, find systems that are running Asterisk, get the list of available extensions, and then hack the passwords. These tools allow a malicious hacker to get into your system and start making long-distance phone calls. There were numerous instances of companies with phone bills reaching into the thousands and even tens of thousands of dollars. Because of issues like this, it is more imperative than ever that you understand how to properly secure your trixbox server from the outside world. In this article by Kerry Garrison, we will focus on how to secure the trixbox server.Read Securing Your trixbox Server in full
