In order to use Asterisk you are going to have to use Linux. If you are a Linux ‘guru’ then you might want to skip this section and just take a look at the dependencies. This section deals with installing a Linux system for use with Asterisk. I make no excuses or arguments for the [...]

The order we compile the applications is important. Compiling them out of order would mean that some of the dependancies of an application might not be fulfilled and things wont work as expected. You will need to be inside the actual directory of the source you are trying to install Compiling libpri Libpri dnt have [...]

Because we are installing from source, they (the source files) will rely on other components of the operating system. The build environment sets up those other components so there wont be errors during the building of the source. Install build environment aptitude install linux-source aptitude install kernel-package aptitude install g++ aptitude install libncurses5-dev aptitude install [...]

We will be using the default install of Debian and installing Asterisk from source and compiling. Debian in my opinion is the best Linux distribution, Asterisk is the best PBX available to us. I have used both of these things in the past and find them a great combination as do many others. We really [...]

Let’s begin our journey into the world of ASTERISK. While Asterisk is the most widely used open source PBX solution, it hasn’t been easy for the average user to take advantage of it. A good, basic knowledge of Linux is a fundamental requirement, as is the ability and nerve to handle the telephony hardware and [...]

So in the last post, you saw how DoS attacks and eavesdropping would be big concerns this year.

“There’s no such thing as a bulletproof VoIP system, but there are things you can do to make your setup more secure” At its heart, a VoIP system is a data network. This means VoIP deployments are vulnerable to the same internal and external threats that plague any enterprise data local area network (LAN) or [...]

In the recent months, VOIP services have gotten more and more attention – both for individual and business purposes. Sometimes, though, we get all caught up in the hype that we may not really see the details. Is VOIP really all that it is made out to be? Does it really bring about advantages? If [...]

VoIP is traditionally thought of as an alternative to the plain-old-telephone system (a.k.a. “POTS” or public switched telephone network). True, it’s usually cheap and would require none of the usual expensive switching equipment that telephone companies usually use. However, users of traditional telephone systems may not be aware that their telcos are ripping them off [...]

Here is something for all Asterisk users out there. Though we may all be very enthusiastic about Asterisk and the service it provides, we have to be practical and keep our eyes open for vulnerabilities. Even the people over at Digium do not act like ostriches and keep their head buried in the sand – [...]
