If you want to check out what the buzz about the new Asterisk 1.4 is, there is one thing you got to do - download it and install it on your box. The compilation procedure is a bit different from the one of Asterisk 1.2, so we thought a brief tutorial would be helpful.

As a point of reference, we imagine you’re going to build your new Asterisk on a machine preinstalled with TrixBox; this means your machine is very easy to reinstall from scratch if anything goes wrong. This also means that you can start playing with Asterisk 1.4 in a virtual machine, so you have no risk.

The first thing you have to do is to create a working directory for Asterisk (say /src/asterisk14beta)and download the latest version of Asterisk 1.4 beta in it; we have used the following:

  • Asterisk Version 1.4.0-beta3

  • Zaptel Version 1.4.0-beta2

  • Libpri Version 1.4.0-beta1

It will also be necessary to erase your existing Asterisk system - see Removing Asterisk. Make sure neither Asterisk nor its required libs are running before attempting the installations.

You’ll also need a bit more software:

  • The C++ developement environment

  • The Iksemel library, in order to test the Google Talk integration (we sure want that!)

  • The Gnu TLS package, as needed by Iksemel


Getting all this software is fairly easy to get installed, thanks to the very powerful yum installed that ships with CentOS:

yum install gcc-g++
yum install gnutls-devel

The first command may download and update quite a lot of stuff; don’t worry and let it run.

You will then download the Iksemel v1.2 libary (first link on the left bar) and compile it like this:

tar zxvf iksemel-1.2.tar.gz
cd iksemel-1.2
make install

Installing Asterisk

The process of installing Asterisk is quite easy, as always. The most important changes have been the adoption of the standard GNU configure utility and a very nice menu configuration utility that will allow a simpler control on what you actually need to build.

tar zxvf zaptel-1.4.0-beta2.tar.gz
cd zaptel-1.4.0-beta2
make menuselect

At this point use the menuselect utility to select which zaptel hardware - if any - you have on board. Please remeber that if you want to exit keeping the changes you made, you must press x , while q will quit without saving.

The rest of the build process is as always was, so:

make install
cd ..

The Libpri library at the moment does not have the fancy new build method, so we revert to a traditional:

tar zxvf libpri-1.4.0-beta1.tar.gz
cd libpri-1.4.0-beta1
make install
cd ..

Now for Asterisk itself; the build process is simple as always. Make sure you have cleaned up your machine before proceeding, to avoid having modules compiled for 1.2 together with stuff for 1.4.

tar zxvf asterisk-1.4.0-beta3.tar.gz
cd asterisk-1.4.0-beta3
make menuselect

Have a tour with the menu select utility. This is a great step forward! it will state clearly which modules you can build and which you cannot, and why. It’s also very easy to turn off stuff you do not want, like channel drivers for protocols you do not need. See how there is a lot of new stuff in 1.4 - we’ll have to spend some time studying it in order to catch up with new stuff! :)

make install
make samples
cd ..

That’s it. Your Asterisk is now ready to rock! Start it up with

asterisk -vvvvvvvvvvvvvvc

And check the current version with the following command:

show version

Here we are. Nice experimenting!

We can try a few new things, like:
